Technical Data

Usage

Simply change the interface type of your can.Bus instance to “wuensche” and adjust the other values (channel) accordingly.
Examples to open a channel with interface from cpcconf.ini or specified directly.
Example 1 CAN: bus = can.Bus(interface=”wuensche”, channel=”CHAN00″, bitrate=500000)
Example 2 CAN: bus = can.Bus(interface=”wuensche”, channel='{ “CHAN” : {“InterfaceType” : “CPC-USB”, “SerialNumber” : “9999999”}}’, bitrate=500000)
Example 3 CAN FD: bus = can.Bus(interface=”wuensche”, channel=”CHAN00″, fd=1, nom_bitrate=1000000, data_bitrate=4000000)
Example 4 CAN FD: bus = can.Bus(interface=”wuensche”, channel=”CHAN00″, fd=1, f_clock=40000000, nom_tseg1=15, nom_tseg2=4, nom_sjw=3, nom_brp=2, data_tseg1=7, data_tseg2=2, data_sjw=1, data_brp=1)
