Introduction

This repository hosts example code for Embedded Proto, the embedded implementation of Google Protocol Buffers. This is an example showing how the NXP FRDM-KE06Z boots with firmware it receives from a CAN network.

Commands are sent from the PC to a USB to CAN converter which is connected to the FDRM-KE06Z.

You can read the full tutorial here.

Requirements

• FDRM-KE06Z
• MCUExpresso
• USB to CAN adapter, like this one
• Dupont cables
• Embedded Proto version 3.4.1 (included as a submodule). The requirements of Embedded Proto are listed here.

Installation

1. Install MCUXpresso if you have not already.
2. Install the dependencies required by Embedded Proto. They are listed here.
3. Clone the repository and auto generate the protobuf files.

git clone --recursive https://github.com/Embedded-AMS/EmbeddedProto_Example_FRDM_CAN_Bootloader.git 
cd EmbeddedProto_Example_FRDM_CAN_Bootloader
python3 setup.py

Running the code

1. Connect the USB to CAN to the FDRM-KE06Z CAN header.
2. Upload the code to the FRDM-KE06Z using MCUExpresso. The board includes the PE-Micro debugger.
3. Run the following instructions

cd EmbeddedProto_Example_FRDM_CAN_Bootloader
source desktop/venv/bin/activate
python3 desktop/main.py desktop/assets/frdmke06z_led_blinky_RED.bin

Debug information will be shown in the terminal. After the booting is done the led will start blinking RED.

There is another example binary to make the led blink GREEN

python3 desktop/main.py desktop/assets/frdmke06z_led_blinky_RED.bin

Have fun!
