This bootloader will use a connected CAN bus to flash new application firmware to the device.This project was built on top to the PlatformIO project in order to simplify the build system and CMSIS dependency.

Before you clone this project, install PlatformIO (PIO) from one of the following ways:
PIO has a great extension for VSCode and you can do all of the development work from there. A guide from PlatformIO can be found here, there is also support for CLion. If you install PIO with this option, you will also be automatically installing the PIO CLI as the editor extensions just provide a nice interaction layer to the PIO tools.
If you want to use your own editor, PIO also has a command line interface for working with PIO projects, information can be found here for setting that up.
cd <per_git_directory>
git clone [email protected]:PurdueElectricRacing/CAN_Bootloader.git
cd CAN_Bootloader
pio build --environment nucleo_l432kc
A good resource for learning how to use PlatformIO is from their documentation, the Tutorials and Examples page has a lot of good content. Most of the videos on YouTube are Arduino-based projects, but all of the pio commands will be very similar to this project
PIO comes with easy integration with the Unity unit testing framework for C. The test directory contains modules that can be run with the pio test -e native command. This will compile the test\<module>\test_<component>.c for your "native" desktop environment and does not require a microcontroller.
Future unit tests can be created for execution on actual ARM hardware, but a large portion of state machine/data structure code can be tested on your local machine.
