stucancommon.driver module

PythonCanDriver.__init__(bitrate, bustype='kvaser')

Initialize PythonCanDriver.can_bus with the specified bitrate for a Kvaser interface if running on Windows, otherwise you must specify your bustype interface such as SocketCAN (not tested yet)

Parameters:bitrate – CAN bus speed

class stucancommon.driver.PythonCanDriver(bitrate, bustype='kvaser')

Bases: object

This class act as a CAN bus interface in order to communicate with the Xcom-CAN, it is NOT intended to access it directly.

can_bus

low-level device specific CAN interface

Type:can.interface.Bus

receive(timeout=100)

Read a message on the CAN bus, waiting block

Parameters:timeout (float) – milli seconds to wait for a message (default 100ms) Returns:identifier, data, dlc, flag, timestamp Return type:tuple

send(identifier, data, is_extended_id=False)

Send a message on the CAN bus

Parameters:

• identifier (int) – The frame identifier used for arbritration on the bus
• data (bytearray) – The data parameter of a CAN message, length from 0 to 8 bytes
• is_extended_id (bool) – Set usage of CAN2.0A (Standard, 11 bits identifier) of CAN2.0B (extended, 29 bits identifier)
