Tested & working: * Send standard packets * Receive standard packets (1 FIFO, no filter) Interoperation between SAM E54 Xplained running this tree and MicroPython running on STM32F405 Feather with an external transceiver was also tested. Many other aspects of a full implementation are not yet present, such as error detection and recovery.
