receive data with CAN

Other Parts Discussed in Thread: HALCOGEN

Good morning everybody,

I've got some problems with the CAN protocol.

Actually, I learn how to send message and RTR but I've got some problems with the receive datas.

I'm using the code generated with Halcogen, but when I try to read datas inside the receiving buffer I don't see the datas that I sent previously to the HDK and this buffer is full of "."

What can I do?

Thanks.

Hi Luigi,

without additional details it is difficult to give advice on what could be the issue in your setup or SW.

However in order to get initial CAN communication up and running I would recommend to use the CAN examples which are provided with Halcogen (example_canCommunication.c or example_canIntCommunication.c). I recently used example_canIntCommunication.c and it worked fine for me. From a HW setup you need to make sure that two CAN transceivers are connected together on the CAN bus side.

Best regards

Andreas
