An Arduino CANFD library for Adafruit Feather M4 CAN #Arduino #canbus
The CANFD Library for Adafruit Feather M4 CAN handles Controller Area Network with Flexible Data (CANFD) for CAN0 and CAN1.
The board contains a CANFD transceiver for CAN1 and the CANH / CANL signals are exposed. For CAN0, TxCAN is D12 and RxCAN is D13.
The library is fully compatible with the MCP2517FD, MCP2518FD CAN Controllers ACAN2517FD library https://github.com/pierremolinaro/acan2517FD, it uses a very similar API and the same CANFDMessage class for handling messages.
The driver supports many bit rates, as standard 62.5 kbit/s, 125 kbit/s, 250 kbit/s, 500 kbit/s, and 1 Mbit/s. An efficient CAN bit timing calculator finds settings for them, but also for exotic bit rates as 833 kbit/s. If the wished bit rate cannot be achieved, the begin method does not configure the hardware and returns an error code.
