C Driver for MCP2515 on STM32 MCU This is a backport of the C++ Arduino driver found here https://github.com/autowp/arduino-mcp2515
SPI settings are hardcoded.
Set the correct HAL includes for the target platform. This has only been used on STM32F4 so far.
I added the MCP_ prefix to the class functions, otherwise the documentations for that project should apply.
