How to test

• Enter driver/tests folder. Select test file by your device type.
• If the channels of device is less than 2:
  • Connect another CAN device with you device's channel for a monitor.
  • Then run the selected testcase.
  • When see receive frame from the monitor, then send frame by the monitor device.
  • It means pass when the testcase exited without any panic.
• If the channels of device is rather than 2:
  • Connected the channels 0 and 1.
  • Then run the selected testcase.
  • It means pass when the testcase exited without any panic.
• All testcase will output the send and received debug info.

The tested device list(include windows and linux):

• USBCAN1 (include office device and deriving device)
• USBCAN2 (only deriving device)
• USBCANFD-200U
• USBCANFD-400U (without supporting channel 3 and 4)
