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.

//| """CAN bus access
|
|
//|
|
|
//| The `_canio` module contains low level classes to support the CAN bus
|
|
//| protocol.
|
|
//|
|
|
//| All classes change hardware state and should be deinitialized when they
|
|
//| are no longer needed if the program continues after use. To do so, either
|
|
//| call :py:meth:`!deinit` or use a context manager. See
|
|
//| :ref:`lifetime-and-contextmanagers` for more info.
|
|
//|
|
|
//| For example::
|
|
//|
|
|
//| import _canio
|
|
//| from board import *
|
|
//|
|
|
//| can = _canio.BUS(board.CANRX, board.CANTX)
|
|
//| can.write(408, b"adafruit")
|
|
//| can.deinit()
|
|
//|
|
|
//| This example will write the data 'adafruit' onto the CAN bus to any
|
|
//| device listening for message id 408."""
