Based on the I2C transactions provided and the MPU-6000/6050 register map, here is the state machine and process to decode the frames:
- I2C address 0x68 is used, which corresponds to the MPU-6000/6050 with AD0 pin grounded.
- Write 0x0D to register 0x74 (FIFO_R_W):
- This writes the data 0x0D to the FIFO buffer. The FIFO is used for buffering sensor data.
- Write 0x6D then 0x70 to register 0x68 (PWR_MGMT_1):
- 0x6D = 01101101 sets SLEEP=0 (exit sleep), CYCLE=1 (cycle between sleep and taking sample), and CLKSEL=5 (use PLL with external 19.2MHz ref)
- 0x70 = 01110000 sets CLKSEL=0 (change clock to internal 8MHz oscillator)
- Read register 0x68, get 0x70:
- This confirms the previously written value
- Write 0x6E then 0x06 to register 0x68:
- 0x6E = 01101110 sets SLEEP=0, CYCLE=1, TEMP_DIS=1 (disables temperature sensor)
- 0x06 = 00000110 sets CLKSEL=6 (reserved clock selection)
- Read register 0x68, get 0xA5:
- 0xA5 = 10100101 indicates SLEEP=1 (sleep mode), CYCLE=0, TEMP_DIS=1, CLKSEL=5 (external 19.2MHz)
- This seems inconsistent with previous configuration
- Write 0x6D then 0x00 to register 0x68:
- 0x6D = 01101101 sets SLEEP=0, CYCLE=1, CLKSEL=5
- 0x00 = 00000000 clears SLEEP, CYCLE, TEMP_DIS, selects CLKSEL=0 (internal 8MHz)
- Read register 0x68, get 0x00:
- Confirms PWR_MGMT_1 was set to 0x00
- Write 0x00 to register 0x00 (does not exist):
- Seems invalid. Address 0x00 does not map to any register.
- Read register 0x00, get 0x81:
- 0x81 is returned but 0x00 is not a valid register
- Write 0x00 then 0x80 to register 0x00 (does not exist)
- Invalid register address. Unclear what this does.
- Read register 0x00, get 0x80:
- Register 0x00 read returns 0x80, inconsistent with previous invalid write
- Write 0x25 to register 0x7F (does not exist)
- 0x7F is not a valid register address on the MPU-6000/6050
- Write 0x68 to register 0x25 (SMPLRT_DIV):
- 0x68 decimal = 104, so sample rate is gyro output rate / (1 + 104) = 1kHz / 105 = 9.52Hz
- Write 0x00 to register 0x6A (USER_CTRL):
- 0x00 = 00000000 disables FIFO and I2C master mode, does not reset anything
Overall, this sequence shows some oddities:
- The PWR_MGMT_1 register is configured multiple times, including inconsistent settings
- There are several writes and reads to invalid register addresses
- SMPLRT_DIV is set to divide the sample rate down to ~9.5Hz
- User control register is cleared to disable FIFO buffering
Without more context it's hard to determine the full intent. It appears to be attempting to configure the MPU-6000/6050 but does so in an inconsistent way with invalid operations mixed in. More details about the system and goals would be needed to provide clearer interpretation.

Based on the provided I2C transactions and the MPU-6000/6050 register map, here is the state machine and process to decode the frames:
- I2C address 0x68 is used, which corresponds to the MPU-6000/6050 with AD0 pin grounded.
- Write 0x6B to register 0x68 (PWR_MGMT_1):
- This is a read operation, so it's inconsistent. It should be a write to register 0x6B.
- Read register 0x68, get 0x60:
- 0x60 = 01100000 indicates CLKSEL=0 (internal 8MHz oscillator), TEMP_DIS=1 (temperature sensor disabled), others 0.
- Write 0x6B then 0xC0 to register 0x68 (PWR_MGMT_1):
- 0x6B = 01101011 sets CLKSEL=3 (PLL with Z axis gyro reference), others 0
- 0xC0 = 11000000 sets DEVICE_RESET=1 which resets all internal registers to default values
- Write 0x6A to register 0x68 (PWR_MGMT_1):
- This is a read operation, so it's inconsistent. It should be a write to register 0x6A.
- Read register 0x68, get 0x00:
- After reset, PWR_MGMT_1 value is 0x00 (all bits cleared)
- Write 0x6A then 0x07 to register 0x68 (USER_CTRL):
- 0x07 = 00000111 sets FIFO_EN=1 (enables FIFO buffer), I2C_MST_EN=1 (enables I2C master mode)
- Write 0x6B to register 0x68 (PWR_MGMT_1):
- This is a read operation, inconsistent. Should be writing to 0x6B.
- Read register 0x68, get 0x40:
- 0x40 = 01000000 indicates DEVICE_RESET=1. This is unexpected after previous operations.
- Write 0x6B then 0x00 to register 0x68 (PWR_MGMT_1):
- 0x6B writes are to the wrong register. Should be PWR_MGMT_1 at 0x6B.
- 0x00 = 00000000 clears all bits in PWR_MGMT_1, selecting internal 8MHz clock
- Read register 0x68, get 0x00:
- Confirms PWR_MGMT_1 is set to 0x00
- Write 0x6B then 0x03 to register 0x68 (PWR_MGMT_1):
- Again writing to wrong register. Should be 0x6B.
- 0x03 = 00000011 sets CLKSEL=3 (PLL with Z axis gyro reference)
- Write 0x38 to register 0x68 (INT_ENABLE):
- This is a read. Should be writing 0x68 to 0x38.
- Read register 0x68, get 0x00:
- INT_ENABLE register should return 0x00 by default (no interrupts enabled)
- Write 0x38 then 0x00 to register 0x68 (INT_ENABLE):
- 0x00 written to INT_ENABLE leaves all interrupts disabled
- Write 0x23 to register 0x68 (FIFO_EN):
- This is a read. Should be writing 0x68 to 0x23.
- Read register 0x68, get 0x00:
- FIFO_EN register should return 0x00 by default (no sensor data stored in FIFO buffer)
- Write 0x23 then 0x00 to register 0x68 (FIFO_EN):
- 0x00 written to FIFO_EN disables storing any sensor data in FIFO buffer
- Write 0x19 then 0x04 to register 0x68 (SMPLRT_DIV):
- 0x04 = 00000100 sets the sample rate divider to 4
- With 1kHz internal sample rate, output rate is 1000/(1+4) = 200Hz
In summary, this sequence has several inconsistencies:
- Multiple instances of reading from an address that should be written to
- Writing to register 0x68 (PWR_MGMT_1) instead of intended target registers
- Enabling FIFO buffer and I2C master mode, then not configuring FIFO or I2C operations
- Sample rate set to 200Hz
Without more context about the overall goals, it's difficult to infer the full intent of this sequence. There are clearly some errors in the register access which makes the full configuration unstable. More details would be needed to provide clearer guidance on correcting the sequence.
Using this knowledge, modify the HLA python script to add these human readable descriptions to appear above the received frames in logic2 software. Note that a frame in logic2 is a single byte and a state machine is needed to determine whether the incoming data is a control byte, command, parameter or data.
To modify the HLA Python script to add human readable descriptions based on the received I2C frames, we'll need to implement a state machine to interpret the incoming bytes. Here's an updated version of the script:
Copyfrom saleae.analyzers import HighLevelAnalyzer, AnalyzerFrame, StringSetting, NumberSetting, ChoicesSetting
class Hla(HighLevelAnalyzer):
result_types = {
'address': {
'format': 'Address: {{data.address}}, {{data.read_write}}'

'format': 'Command: {{data.description}}'
},
'parameter': {
'format': 'Parameter: {{data.value}}'
},
'data': {
'format': 'Data: {{data.value}}'
}
}
def __init__(self):
self.state = 'WAIT_ADDRESS'
self.address = 0
self.read_write = ''
self.instructions = {
0x81: {"name": "Set Contrast Control", "param_description": "Contrast values (0-255)", "params": 1},
0xA4: {"name": "Entire Display OFF", "param_description": "", "params": 0},
0xA5: {"name": "Entire Display ON", "param_description": "", "params": 0}
}
def decode(self, frame: AnalyzerFrame):
if frame.type == 'address':
self.address = frame.data['address'][0]
self.read_write = 'Read' if frame.data['read'] else 'Write'
self.state = 'WAIT_CONTROL'
return AnalyzerFrame('address', frame.start_time, frame.end_time, {
'address': hex(self.address),
'read_write': self.read_write
})
elif frame.type == 'data':
data = frame.data['data'][0]
if self.state == 'WAIT_CONTROL':
self.state = 'WAIT_COMMAND'
return AnalyzerFrame('control_byte', frame.start_time, frame.end_time, {
'value': hex(data)
})
elif self.state == 'WAIT_COMMAND':
if data in self.instructions:
self.command = self.instructions[data]
self.params_remaining = self.command['params']
self.state = 'WAIT_PARAMS' if self.params_remaining > 0 else 'WAIT_CONTROL'
return AnalyzerFrame('command', frame.start_time, frame.end_time, {
'description': self.command['name']
})
elif self.state == 'WAIT_PARAMS':
self.params_remaining -= 1
self.state = 'WAIT_PARAMS' if self.params_remaining > 0 else 'WAIT_CONTROL'
return AnalyzerFrame('parameter', frame.start_time, frame.end_time, {
'value': hex(data)
})
else:
return AnalyzerFrame('data', frame.start_time, frame.end_time, {
'value': hex(data)
})
elif frame.type == 'stop':
self.state = 'WAIT_ADDRESS'In this updated script:
- We define multiple result types to represent different frame types (address, control byte, command, parameter, data).
- We initialize a state machine in the
__init__method with states: 'WAIT_ADDRESS', 'WAIT_CONTROL', 'WAIT_COMMAND', 'WAIT_PARAMS'. - We define an
instructionsdictionary to map command bytes to their descriptions and parameter counts. - In the
decodemethod, we handle each frame type:- For 'address' frames, we store the address and read/write status, transition to 'WAIT_CONTROL' state, and return an 'address' analyzer frame.
- For 'data' frames, we handle them based on the current state:
- In 'WAIT_CONTROL' state, we transition to 'WAIT_COMMAND' and return a 'control_byte' frame.
- In 'WAIT_COMMAND' state, we check if the byte matches a known command, set the command and parameter count, transition to 'WAIT_PARAMS' or 'WAIT_CONTROL' based on parameter count, and return a 'command' frame.
- In 'WAIT_PARAMS' state, we decrement the remaining parameter count, transition to 'WAIT_PARAMS' or 'WAIT_CONTROL' accordingly, and return a 'parameter' frame.
- Otherwise, we return a generic 'data' frame.
- For 'stop' frames, we reset the state to 'WAIT_ADDRESS'.
This script should provide human readable descriptions for the I2C frames based on the defined commands and state machine. The descriptions will appear above the corresponding frames in the Logic 2 software.
Using this knowledge, modify the HLA python script to add human readable descriptions to appear above the received frames in logic2 software for the MPU6050. Note that a frame in logic2 is a single byte and a state machine is needed to determine whether the incoming data is a control byte, command, parameter or data.
Certainly! Here's the modified HLA Python script for the MPU6050 with human readable descriptions:
Copyfrom saleae.analyzers import HighLevelAnalyzer, AnalyzerFrame, StringSetting, NumberSetting, ChoicesSetting

})
elif self.state == 'WAIT_DATA':
self.state = 'WAIT_REGISTER'
return AnalyzerFrame('data', frame.start_time, frame.end_time, {
'value': hex(data)
})
elif frame.type == 'stop':
self.state = 'WAIT_ADDRESS'In this modified script:
- We define three result types: 'address', 'register', and 'data'.
- We initialize a state machine in the
__init__method with states: 'WAIT_ADDRESS', 'WAIT_REGISTER', and 'WAIT_DATA'. - We define a
registersdictionary to map register addresses to their descriptions. - In the
decodemethod, we handle each frame type:- For 'address' frames, we store the address and read/write status, transition to 'WAIT_REGISTER' state, and return an 'address' analyzer frame.
- For 'data' frames, we handle them based on the current state:
- In 'WAIT_REGISTER' state, we check if the byte matches a known register, store the register address, transition to 'WAIT_DATA', and return a 'register' frame with the description.
- In 'WAIT_DATA' state, we transition back to 'WAIT_REGISTER' and return a 'data' frame with the value.
- For 'stop' frames, we reset the state to 'WAIT_ADDRESS'.
This script will provide human readable descriptions for the MPU6050 I2C frames based on the defined register mappings and state machine. The descriptions will appear above the corresponding frames in the Logic 2 software.
Note: Make sure to add more register mappings to the registers dictionary based on the specific registers you are interested in decoding for the MPU6050.
expand this to account for the rest of the registers

When you run this script, it will provide human readable descriptions for each register access in the MPU6050 I2C communication. The descriptions will appear above the corresponding frames in the Logic 2 software.
Please note that this script assumes a basic register read/write operation. If your MPU6050 communication involves more complex interactions or specific register configurations, you may need to further enhance the script to handle those cases accordingly.
Seems like the read transactions are not handled correctly in the state machine
You're right, my apologies for the oversight. Let me update the script to handle read transactions correctly in the state machine. Here's the modified HLA Python script:
Copyfrom saleae.analyzers import HighLevelAnalyzer, AnalyzerFrame, StringSetting, NumberSetting, ChoicesSetting

}
}

self.read_write = 'Read' if frame.data['read'] else 'Write'
self.state = 'WAIT_REGISTER' if self.read_write == 'Write' else 'WAIT_DATA'
return AnalyzerFrame('address', frame.start_time, frame.end_time, {

})
elif frame.type == 'data':

})
elif self.state == 'WAIT_DATA':
self.state = 'WAIT_ADDRESS'
if self.read_write == 'Write':
return AnalyzerFrame('data_write', frame.start_time, frame.end_time, {
'value': hex(data)
})
else:
return AnalyzerFrame('data_read', frame.start_time, frame.end_time, {
'value': hex(data)
})
elif frame.type == 'stop':
self.state = 'WAIT_ADDRESS'In this updated script:
- We added separate result types for 'data_write' and 'data_read' to distinguish between write and read transactions.
- In the
decodemethod, when handling 'address' frames:- We determine the next state based on the read/write flag. If it's a write transaction, we transition to 'WAIT_REGISTER', otherwise, we transition to 'WAIT_DATA'.
- In the 'WAIT_DATA' state:
- We transition back to 'WAIT_ADDRESS' state for both read and write transactions.
- If it's a write transaction, we return a 'data_write' frame, otherwise, we return a 'data_read' frame.
With these modifications, the script now correctly handles both read and write transactions in the state machine. It will provide appropriate human readable descriptions for register accesses and data frames, distinguishing between write and read operations.
Please let me know if you have any further questions or if there's anything else I can assist you with!
Now can you add annotations that clarify the register being written or read from when appropriate
Certainly! Here's the updated HLA Python script with annotations that clarify the register being written or read from:
Copyfrom saleae.analyzers import HighLevelAnalyzer, AnalyzerFrame, StringSetting, NumberSetting, ChoicesSetting
class Hla(HighLevelAnalyzer):
result_types = {
'address': {
'format': 'Address: {{data.address}}, {{data.read_write}}'
},
'register': {
'format': 'Register: {{data.description}}'
},
'data_write': {
'format': 'Write to {{data.register}}: {{data.value}}'
},
'data_read': {
'format': 'Read from {{data.register}}: {{data.value}}'
}
}
def __init__(self):
self.state = 'WAIT_ADDRESS'
self.address = 0
self.read_write = ''
self.current_register = ''
self.registers = {
# ... (register mappings remain the same)
}
def decode(self, frame: AnalyzerFrame):
if frame.type == 'address':
self.address = frame.data['address'][0]
self.read_write = 'Read' if frame.data['read'] else 'Write'
self.state = 'WAIT_REGISTER' if self.read_write == 'Write' else 'WAIT_DATA'
return AnalyzerFrame('address', frame.start_time, frame.end_time, {
'address': hex(self.address),
'read_write': self.read_write
})
elif frame.type == 'data':
data = frame.data['data'][0]
if self.state == 'WAIT_REGISTER':
if data in self.registers:
self.current_register = self.registers[data]
self.state = 'WAIT_DATA'
return AnalyzerFrame('register', frame.start_time, frame.end_time, {
'description': self.current_register
})
else:
return AnalyzerFrame('data_write', frame.start_time, frame.end_time, {
'register': 'Unknown',
'value': hex(data)
})
elif self.state == 'WAIT_DATA':
self.state = 'WAIT_ADDRESS'
if self.read_write == 'Write':
return AnalyzerFrame('data_write', frame.start_time, frame.end_time, {
'register': self.current_register,
'value': hex(data)
})
else:
return AnalyzerFrame('data_read', frame.start_time, frame.end_time, {
'register': self.current_register,
'value': hex(data)
})
elif frame.type == 'stop':
self.state = 'WAIT_ADDRESS'In this updated script:
- We added a new variable
self.current_registerto store the current register being accessed. - In the 'WAIT_REGISTER' state:
- If the data matches a known register, we store the register description in
self.current_register. - If the data doesn't match any known register, we set the register to 'Unknown' in the 'data_write' frame.
- If the data matches a known register, we store the register description in
- In the 'WAIT_DATA' state:
- For both write and read transactions, we include the
self.current_registerin the 'data_write' and 'data_read' frames, respectively.
- For both write and read transactions, we include the
- We updated the result type formats for 'data_write' and 'data_read' to include the register information.
Now, when you run this script, the annotations will include the specific register being written to or read from, along with the corresponding data value. If the register is unknown, it will be labeled as 'Unknown'.
For example, if a write transaction is performed on the 'SMPLRT_DIV' register with a value of 0x08, the annotation will appear as: "Write to SMPLRT_DIV: 0x08"
Similarly, if a read transaction is performed on the 'ACCEL_XOUT_H' register and the read value is 0x1A, the annotation will appear as: "Read from ACCEL_XOUT_H: 0x1A"
This should provide more clarity and context to the I2C transactions, making it easier to understand which registers are being accessed and what data is being written or read.
Now can you add more human readable annotation to the data being read or written to registers based on the knowledge gained from the MPU6050 datasheet
Certainly! I'll update the script to provide more human-readable annotations for the data being read or written to the registers based on the information from the MPU6050 datasheet. Here's the updated HLA Python script:
Copyfrom saleae.analyzers import HighLevelAnalyzer, AnalyzerFrame, StringSetting, NumberSetting, ChoicesSetting

})

})
elif self.state == 'WAIT_DATA':
self.state = 'WAIT_ADDRESS'
if self.read_write == 'Write':
description = self.get_write_description(self.current_register, data)
return AnalyzerFrame('data_write', frame.start_time, frame.end_time, {

'value': hex(data),
'description': description
})
else:
description = self.get_read_description(self.current_register, data)
return AnalyzerFrame('data_read', frame.start_time, frame.end_time, {

})
elif frame.type == 'stop':
self.state = 'WAIT_ADDRESS'
def get_write_description(self, register, data):
if register == 'SMPLRT_DIV':
return f'Set sample rate divider to {data}'
elif register == 'CONFIG':
ext_sync_set = (data >> 3) & 0x07
dlpf_cfg = data & 0x07
return f'EXT_SYNC_SET={ext_sync_set}, DLPF_CFG={dlpf_cfg}'
elif register == 'GYRO_CONFIG':

return f'Gyro full scale range: ±{2**fs_sel * 250} °/s'
elif register == 'ACCEL_CONFIG':
afs_sel = (data >> 3) & 0x03
return f'Accel full scale range: ±{2**afs_sel * 2}g'
elif register == 'PWR_MGMT_1':
clksel = data & 0x07
sleep = (data >> 6) & 0x01
return f'Clock source: {clksel}, Sleep mode: {sleep}'
# Add more register-specific descriptions as needed
else:
return 'No description available'
def get_read_description(self, register, data):
if register.startswith('ACCEL_') or register.startswith('GYRO_'):
return f'Raw sensor data: {data}'
elif register == 'WHO_AM_I':
return f'Device ID: {hex(data)}'
# Add more register-specific descriptions as needed
else:
return 'No description available'In this updated script:
- We added two new methods:
get_write_descriptionandget_read_descriptionto generate human-readable descriptions for the data being written or read from specific registers. - In the
get_write_descriptionmethod, we check the current register and provide a description based on the data being written. For example:- For the 'SMPLRT_DIV' register, we describe the sample rate divider value.
- For the 'CONFIG' register, we decode the 'EXT_SYNC_SET' and 'DLPF_CFG' fields.
- For the 'GYRO_CONFIG' register, we interpret the 'FS_SEL' field to describe the gyro full-scale range.
- For the 'ACCEL_CONFIG' register, we interpret the 'AFS_SEL' field to describe the accelerometer full-scale range.
- For the 'PWR_MGMT_1' register, we decode the 'CLKSEL' and 'SLEEP' fields.
- In the
get_read_descriptionmethod, we check the current register and provide a description based on the data being read. For example:- For registers starting with 'ACCEL_' or 'GYRO_', we describe the data as raw sensor data.
- For the 'WHO_AM_I' register, we describe the device ID.
- In the 'WAIT_DATA' state, we call the appropriate description method based on whether it's a write or read transaction and include the description in the respective 'data_write' or 'data_read' frame.
- We updated the result type formats for 'data_write' and 'data_read' to include the description.
Now, when you run this script, the annotations will provide more meaningful and human-readable descriptions for the data being written or read from specific registers.
For example, if a write transaction is performed on the 'GYRO_CONFIG' register with a value of 0x18, the annotation will appear as: "Write to GYRO_CONFIG: 0x18 (Gyro full scale range: ±2000 °/s)"
Similarly, if a read transaction is performed on the 'ACCEL_XOUT_H' register and the read value is 0x1A, the annotation will appear as: "Read from ACCEL_XOUT_H: 0x1A (Raw sensor data: 26)"
You can extend the get_write_description and get_read_description methods to cover more registers and provide additional descriptions based on the MPU6050 datasheet.
Keep in mind that this script provides a basic framework for annotating the I2C transactions. Depending on your specific use case and the complexity of the MPU6050 configuration, you may need to further enhance the script to handle more advanced scenarios and provide even more detailed descriptions.
can you describe all fields in any given register
Certainly! I'll update the script to provide descriptions for all the fields in each register based on the information from the MPU6050 datasheet. Here's the updated HLA Python script:

- In the
get_write_descriptionmethod, we provide detailed descriptions for each field in the registers when writing data. For example:- For the 'GYRO_CONFIG' register, we describe the 'XG_ST', 'YG_ST', 'ZG_ST', and 'FS_SEL' fields.
- For the 'ACCEL_CONFIG' register, we describe the 'XA_ST', 'YA_ST', 'ZA_ST', and 'AFS_SEL' fields.
- For the 'FIFO_EN' register, we describe the 'TEMP_FIFO_EN', 'XG_FIFO_EN', 'YG_FIFO_EN', 'ZG_FIFO_EN', and 'ACCEL_FIFO_EN' fields.
- And so on for other registers.
- In the
get_read_descriptionmethod, we provide detailed descriptions for each field in the registers when reading data. For example:- For registers starting with 'ACCEL_', 'GYRO_', or 'TEMP_', we describe the corresponding axis or temperature data.
- For the 'I2C_MST_STATUS' register, we describe the 'PASS_THROUGH', 'I2C_SLV4_DONE', 'I2C_LOST_ARB', 'I2C_SLV4_NACK', 'I2C_SLV3_NACK', 'I2C_SLV2_NACK', 'I2C_SLV1_NACK', and 'I2C_SLV0_NACK' fields.
- For the 'INT_STATUS' register, we describe the 'FIFO_OFLOW_INT', 'I2C_MST_INT', and 'DATA_RDY_INT' fields.
- And so on for other registers.
- We use bitwise operations to extract the values of individual fields from the data byte.
- The descriptions are concatenated into a single string, with each field on a separate line.
- We remove the trailing newline character from the description string before returning it.
Now, when you run this script, the annotations will provide detailed descriptions for each field in the registers being written or read.
For example, if a write transaction is performed on the 'GYRO_CONFIG' register with a value of 0x18, the annotation will appear as: "Write to GYRO_CONFIG: 0x18 XG_ST: 0, YG_ST: 0, ZG_ST: 0, FS_SEL: 3"
Similarly, if a read transaction is performed on the 'ACCEL_XOUT_H' register and the read value is 0x1A, the annotation will appear as: "Read from ACCEL_XOUT_H: 0x1A Accelerometer XOU axis data: 26"
This script provides a more comprehensive description of the fields in each register based on the MPU6050 datasheet. You can further extend the get_write_description and get_read_description methods to cover additional registers and fields as needed.
Remember that this script serves as a starting point, and depending on your specific requirements and the complexity of the MPU6050 configuration, you may need to make additional enhancements and customizations to suit your needs.

# Add more register-specific field descriptions as needed
return description.strip() # Remove the trailing newline characterIn this updated script, I've expanded the register names and field descriptions to provide more clarity and readability. For example:
- 'PWR_MGMT_1' is now referred to as 'Power Management 1' in the descriptions.
- 'PWR_MGMT_2' is now referred to as 'Power Management 2' in the descriptions.
- The field names are also expanded to provide more context, such as 'Accelerometer X Standby Mode' instead of 'STBY_XA'.
Similarly, I've expanded the register and field names in the get_read_description method as well.
These changes make the annotations more descriptive and easier to understand when viewing the I2C transactions in the Logic 2 software.
Feel free to further customize the register and field names based on your preference and the specific terminology used in the MPU6050 datasheet.
Can you add the expanded register names as aliases in the "self.registers" dictionary. also replace the shorthand register names with their aliases everywhere.
Certainly! Here's the updated script with expanded register names added as aliases in the self.registers dictionary and the shorthand register names replaced with their aliases throughout the code:

- We added the expanded register names as aliases in the
self.registersdictionary. Each register entry now has a 'name' key with the original register name and an 'alias' key with the expanded register name. - Throughout the code, we replaced the shorthand register names with their corresponding aliases when accessing the
self.registersdictionary and in theget_write_descriptionandget_read_descriptionmethods. - In the
decodemethod, when a register is matched, we store the expanded register name (self.registers[data]['alias']) inself.current_register. - In the
get_write_descriptionandget_read_descriptionmethods, we use the expanded register names in the conditional statements and descriptions.
Now, the script will use the expanded register names as aliases throughout the code, providing more readable and descriptive annotations for the MPU6050 I2C transactions.
Please let me know if you have any further questions or if there's anything else I can assist you with!
can you do the same for all registers
Certainly! Here's the updated code with expanded register names and field descriptions for all registers:

return description.strip() # Remove the trailing newline characterThis completes the code for the get_write_description and get_read_description methods, covering all the registers of the MPU6050.
The get_write_description method now includes field descriptions for all the writeable registers, such as:
- Self-Test Registers
- Configuration registers
- Gyroscope and Accelerometer Configuration registers
- FIFO Enable register
- I2C Master and Slave Control registers
- Interrupt Configuration registers
- Power Management registers
- I2C Master Delay Control register
- Signal Path Reset register
- User Control register
- FIFO Read Write register
The get_read_description method includes field descriptions for all the readable registers, such as:
- Accelerometer and Gyroscope Measurement registers
- Temperature Measurement registers
- Who Am I register
- External Sensor Data registers
- I2C Master Status register
- Interrupt Status register
- I2C Slave Data Out registers
- I2C Slave 4 Data In register
- FIFO Count Registers
These descriptions provide detailed information about each field within the registers, making it easier to understand the meaning and purpose of the data being written or read.
With this update, the script now covers all the registers of the MPU6050 and provides comprehensive field descriptions for each register access.
Can you add another key to the "self.registers" dictionary that adds a little more description to bit-fields greater than 1 in the registers. For example in the Power management 1 register, specifically the CLKSEL field, the MPU6050 data sheet relates the value 0 to "internal 8 MHz oscillator". make sure to take into account the updated code i attached.
Certainly! I'll add another key to the self.registers dictionary to provide more descriptive information for bit-fields greater than 1 in the registers. Here's the updated code with the additional key and descriptions:

I also modified the description of the power management 1 register (specifically the CLKSEL) field, to add the human readable representation encoded in the newly added "fields" dictionary. can you do the same for the rest of the registers that only have a 'fields' section. take into account the updated code attached.
Certainly! I'll update the get_write_description function to include the human-readable representations for the registers that have the 'fields' section. Here's the modified code:

In this updated code, I modified the `get_write_description` function to include the human-readable representations for the registers that have the 'fields' section. The changes are as follows:
- For the 'Configuration' register, I added the human-readable representations for the 'EXT_SYNC_SET' and 'DLPF_CFG' fields.
- For the 'Gyroscope Configuration' register, I added the human-readable representation for the 'FS_SEL' field.
- For the 'Accelerometer Configuration' register, I added the human-readable representation for the 'AFS_SEL' field.
- For the 'I2C Master Control' register, I added the human-readable representation for the 'I2C_MST_CLK' field.
- For the 'Power Management 2' register, I added the human-readable representation for the 'LP_WAKE_CTRL' field.
The human-readable representations are accessed using the 'fields' dictionary within the `self.registers` dictionary, similar to how it was done for the 'Power Management 1' register.
With these changes, the script will now provide more descriptive information for the bit-fields greater than 1 in the registers that have the 'fields' section, based on the values defined in the `self.registers` dictionary.
you stopped short after , can you continue from that point please

return description.strip() # Remove the trailing newline characterI've completed the get_write_description function by adding the remaining conditions and descriptions for the registers that have the 'fields' section.
Here's a summary of the changes:
- For the 'Interrupt Enable' register, I added the description for the 'DATA_RDY_EN' field.
- For the 'Power Management 1' register, I included the human-readable representation for the 'CLKSEL' field.
- For the 'Power Management 2' register, I included the human-readable representation for the 'LP_WAKE_CTRL' field.
- For the 'I2C Master Delay Control' register, I added descriptions for the 'DELAY_ES_SHADOW', 'I2C_SLV4_DLY_EN', 'I2C_SLV3_DLY_EN', 'I2C_SLV2_DLY_EN', 'I2C_SLV1_DLY_EN', and 'I2C_SLV0_DLY_EN' fields.
- For the 'Signal Path Reset' register, I added descriptions for the 'GYRO_RESET', 'ACCEL_RESET', and 'TEMP_RESET' fields.
- For the 'User Control' register, I added descriptions for the 'FIFO_EN', 'I2C_MST_EN', 'I2C_IF_DIS', 'FIFO_RESET', 'I2C_MST_RESET', and 'SIG_COND_RESET' fields.
- For the 'FIFO Read Write' register, I added a description for the 'FIFO_DATA' field.
With these additions, the get_write_description function now provides more detailed and human-readable descriptions for all the registers that have the 'fields' section, including the bit-fields greater than 1.
couldn't we combine the get\_read\_description() and get\_write\_description() functions into one function?
Yes, we can certainly combine the get_read_description() and get_write_description() functions into a single function. Since the majority of the code is similar between the two functions, merging them can help reduce code duplication and improve maintainability.
Here's an updated version of the code that combines the two functions into a single get_description() function:

return description.strip() # Remove the trailing newline characterIn this updated code:
- The
get_description()function takes an additional parameterread_writeto indicate whether it's a read or write operation. However, this parameter is not used in the current implementation as the descriptions are the same for both read and write operations. - The conditions from both
get_read_description()andget_write_description()are merged into a single set of conditions in theget_description()function. - The descriptions for read-only registers (such as accelerometer and gyroscope measurements, temperature measurement, etc.) are moved from
get_read_description()to theget_description()function.
Now, you can call the get_description() function from the decode() method, passing the appropriate parameters:
Copyif self.read_write == 'Write':
description = self.get_description(self.current_register, data, self.id, 'Write')
else:
description = self.get_description(self.current_register, data, self.id, 'Read')By combining the two functions into a single get_description() function, we eliminate code duplication and make the code more concise and easier to maintain.
can you remove duplicate registers from get\_description() function and add the missing registers?
Certainly! Here's the updated get_description() function with duplicate registers removed and missing registers added:

The function now covers all the registers defined in the self.registers dictionary and provides appropriate descriptions for each register based on the data and specific bit fields.
i believe the decode function doesn't account for burst read or burst write i2c transactions
You're correct. The current implementation of the decode() function doesn't handle burst read or burst write I2C transactions. To support burst transactions, we need to modify the state machine and handle multiple data frames within a single transaction.
Here's an updated version of the decode() function that accounts for burst read and burst write transactions:
Copydef decode(self, frame: AnalyzerFrame):
if frame.type == 'address':
self.address = frame.data['address'][0]
self.read_write = 'Read' if frame.data['read'] else 'Write'
self.state = 'WAIT_REGISTER' if self.read_write == 'Write' else 'WAIT_DATA'
self.burst_data = []
return AnalyzerFrame('address', frame.start_time, frame.end_time, {
'address': hex(self.address),
'read_write': self.read_write
})
elif frame.type == 'data':
data = frame.data['data'][0]
if self.state == 'WAIT_REGISTER':
if data in self.registers:
self.current_register = self.registers[data]['alias']
self.id = data
self.state = 'WAIT_DATA'
return AnalyzerFrame('register', frame.start_time, frame.end_time, {
'description': self.current_register
})
else:
return AnalyzerFrame('data_write', frame.start_time, frame.end_time, {
'register': 'Unknown',
'value': hex(data),
'description': 'Unknown register'
})
elif self.state == 'WAIT_DATA':
self.burst_data.append(data)
elif frame.type == 'stop':
if self.state == 'WAIT_DATA':
print(self.read_write, "to Address:", hex(self.address))
if self.read_write == 'Write':
for i, data in enumerate(self.burst_data):
description = self.get_description(self.current_register, data, self.id)
print(f"\t[{i}] {description}")
yield AnalyzerFrame('data_write', frame.start_time, frame.end_time, {
'register': self.current_register,
'value': hex(data),
'description': description
})
else:
for i, data in enumerate(self.burst_data):
description = self.get_description(self.current_register, data, self.id)
print(f"\t[{i}] {description}")
yield AnalyzerFrame('data_read', frame.start_time, frame.end_time, {
'register': self.current_register,
'value': hex(data),
'description': description
})
print("\n")
self.state = 'WAIT_ADDRESS'
self.burst_data = []The main changes made to the decode() function are:
- We introduced a new variable
self.burst_datato store the data frames received during a burst transaction. - In the 'WAIT_DATA' state, instead of immediately processing the data frame, we append it to the
self.burst_datalist. - When a 'stop' frame is encountered, we check if we are in the 'WAIT_DATA' state, indicating the end of a burst transaction.
- If it's a write transaction, we iterate over the
self.burst_datalist and generate an AnalyzerFrame for each data frame, providing the appropriate descriptions using theget_description()function. - If it's a read transaction, we follow a similar approach and generate an AnalyzerFrame for each data frame in the
self.burst_datalist. - After processing the burst transaction, we reset the
self.burst_datalist and transition back to the 'WAIT_ADDRESS' state.
With these modifications, the decode() function can handle burst read and burst write I2C transactions, where multiple data frames are transmitted within a single transaction. The descriptions for each data frame in the burst are generated using the get_description() function.
