CANMessageGet incorrect length

Bradley Higgin

For some reason, CANMessageGet( ) is receiving the correct ID; however, the length is incorrect (1B). Data[0] is correct, as well.

Looking through CANMessageGet(), I see CAN_IF1MCTL and CAN_IF2MCTL are '&' together to produce the DLC (length).

CAN_IF1MCTL = 0x00001F88

CAN_IF2MCTL = 0x0000B401

Any ideas?

Bradley,

It's difficult to infer from what you have posted. Can you share a few more details:

1) Can you describe you board/HW setup? For example, which device or DK (3rd party/Tiva/Stellaris DevKit) is sending CAN data and which device is receiving? Please also can what CAN ports you are using.

2) Could you please share your CAN init and inline CANMessageGet() code fro me to review.

Thanks,
Chris

Seems it was an issue with my CAN simulator...
