FFS - First Functioning Software

Policumbent's on board Raspberry Pi's software (modules) which will manage:

• ANT+ sensors
• Video and digital camera
• CAN Bus communications and logging

General understanding

Since the Raspberry Pi manages both the digital screen (with the Raspberry Pi Camera Module) and data gathering (via ANT+ and CAN bus), we need a software that takes care of all of that.

Modules communication

Since FFS is made up by three modules (ant, can, video) which communicate with each other with OS FIFOs.

FIFO messages

ANT module

Sends	Sensor Name
ANT Speed	ant_speed
ANT Distance	ant_distance
Power	power
Cadence	cadence
Heartrate	heartrate

It does not receive anything from the other modules.

CAN module

Sends	Sensor Name
Gear	gear
GNSS Speed	gnss_speed
GNSS Displacement	gnss_displacement

Receives	Sensor Name
Power	power
Cadence	cadence
Heartrate	heartrate

Video module

Receives	Sensor Name
ANT Speed	ant_speed
ANT Distance	ant_distance
Power	power
Cadence	cadence
Heartrate	heartrate
Gear	gear
GNSS Speed	gnss_speed
GNSS Displacement	gnss_displacement
