Using CAN on SPC560B-DIS

Hello,

I am trying to make a simple project that for a start can send a single CAN frame.

I am using the SPC560B-DIS evb without any CAN board (will connect later on my own converter).

I took a CAN sample from other evb and merged it to my project but it doesn't work!

Is there any CAN sample that works that I can use?

Can I connect a scope to the TX pin and view the data without converter to CAN High and CAN Low?

In the example i did not see any initialization to the I/O (Tx and Rx) is that correct?

Can I use the external clock on my board for the CAN module?

Thanks

Shachar

Hello Erwan,

I have the same question than other people in this post.

I want to use a CAN port with the SPC560B-DIS.

I have donloaded the ''SPC560Bxx OS-Less CAN Test Application for Discovery'' configuration that you have given in your last post and I try to configure it for use the FlexCAN0 module: I disable loopback mode, but I can't see anyt signals with my scope on TX and RX ((PB[0] and PB[1]).

My application is in attachment: can you say me what is wrong?

Thanks for your help,

Sylvain

Hello Sylvain ,

i do not see any filters on your CAN configuration.

How do you check your CAN Frame transmission ?

Best Regards

Erwan
