systeccan

The ucan module is a Python wrapper based on the (c) SYSTEC electronic GmbH USBcanServer wrapper class.

Requires the driver package USB-CANmodul Utility Disk with the USBCAN32.DLL library to be installed from https://www.systec-electronic.com/en/products/interfaces-gateways/sysworxx-usb-canmodul1

The module exposes base class USBCanServer which can be subclassed to handle connection events, message reception events and etc.

Example

from ucan import *

# create the USB CAN server
can = USBCanServer()

# initialize the hardware
can.init_hardware()

# initialize channel 0 with bitrate 125000
can.init_can(channel=Channel.CHANNEL_CH0, BTR=Baudrate.BAUD_125kBit)

# create standard CAN message
msg = CanMsg(id=0x12, frame_format=MsgFrameFormat.MSG_FF_STD, data=[0x00, 0x01])

# write the message
can.write_can_msg(Channel.CHANNEL_CH0, [msg])

# shutdown the channels and hardware
can.shutdown()
