CAN protocol

Luigi Ventriglia

Other Parts Discussed in Thread: HALCOGEN

Hi everybody,

I don't understand how the CAN protocol works inside the Hercules development kit TMS570 MCU.

I need some explanations. I have a demo code but I've got some troubles about the setting of the registers and the configurations of the messagge object.

Can someone help me?

Thanks.

I would recommend to start wit some simple CAN-code, generated by HalCoGen. The you can use the autogenerated code to inspect the register setup. All CAN registers are explained in the TMS570 TRM.

OK,

can you suggest me how to procede or where can I find some demos?

What is the TMS570 TRM?

Thanks.

TRM is the technical reference manual, for the TMS570 search for "spnu499.pdf"

I have attached a simple getting started CAN example from my workshop.

Thanks for your support,

I've got another question: how can I define an RTR message with HalcGen?

No, currently HalCoGen does not support RTR.
