An example implementation of the Microchip MC2515 CAN Controller.
This project uses a PIC32MX130F064B to interface with the MCP2515.
This software repeatedly sends CAN message 0x18FABC33 with increasing values in the data bytes. It is configured for a bus speed of 250k assuming an oscillator frequency of 10MHz. Paired with an MCP2562 CAN transciever, this code has been tested working using both a Kvaser Leaf Lite and PCAN IPEH-002021.
This project was breadboarded; to aid in debugging, the PIC32 also initializes UART2 to send data to an MCP2221A USB transciever (115200 baud). I've provided a short Powershell script that will read this terminal output, but you may need to edit 'COM3' to whatever your USB-UART bridge ends up enumerating to.
All MPLABX project files are included. If you're looking for just the source code, it's in MCP2515-Example.X/src.
I have also included the breadboard schematic. It is a bare-minimum implementation that gets things to work - it leaves a lot of room for improvement. Yes, all capacitors and resistors are required (ask me how I know).
