Set CAN Bus not working with PCANUSB #1
Description
Hey,
Curf.py: in set_can both self.bus and self.logbus are trying to initialize to same device. This is not possible, and will result as an error when trying to connect logbus.
I removed all the logging and got it working:
-modification in curf.py
def set_can(self, interface, channel, bitrate, db=None, test_name=None):
""" Set the CAN BUS
Keyword arguments:
interface -- can interface (socketcan, vector, ...)

Stop CAN Bus
Stop Bus

*** Test Cases ***
Send a CAN frame
Send Frame With ID 0x5D3 And DEADBEEF As Data
Send a given signal
Send Signal SENSOR_SONARS_err_count With Value 0
-Proof it works:
