Issue Details

I would like to be able to dynamically modify the CRC values of CAN frames sent with the NI-XNET driver. Is there any way of doing it ?


CRC values are both generated and checked in the hardware of the XNET device. At this time, XNET does not support user level manipulation of CRC values. A possible workaround however would be to calculate the custom CRC values and include them as part of the frame payload.
