My issue is resolved. I had to make some changes related to buffer input in the set value vi I had created using the dll. The example you shared was helpful.

I am using my own

Earlier I was not passing any value to buffer length so I am guessing it was taking the default value as 0 and I wasn’t getting any error. But after looking at the example you provided I passed 4 as the value for buffer length and now with buffer length 4 I am getting unknown error.

It’s the error code returned from CAN_SetValue function.
The error value is 65536 which signifies ‘PCAN_ERROR_UNKNOWN - Unknown error’.

I was not setting the buffer length before.

But now after setting the buffer length I am getting unknown error.

Could you please check the attachment and confirm if the values I am setting are correct or not?

I have created labview vi using pcan basic dll. I am able to read and write the messages but I am not able to capture a trace using pcan basic api.

I have set following parameters using CAN_SetValue function-
1. PCAN_TRACE_LOCATION
2. PCAN_TRACE_STATUS
3. PCAN_TRACE_SIZE
4. PCAN_TRACE_CONFIGURE ...
