How to use Hercules to talk to a motor controller via CANBUS?

Other Parts Discussed in Thread: HALCOGEN

Hi all,

I've not used Hercules before and far from being proficient in using CAN-BUS protocol. I'm wondering if anyone who has used Hercules before could shed any light on how to use HerculesTMS570 to talk to a motor controller (Roboteq SDC2160). It's also my first time using CCS as an IDE.

Thanks a lot

Hello:

I would recommend you to pick one of our development boards (www.ti.com/.../tools_software.page, install HALCoGen (www.ti.com/.../halcogen) and run some of the included examples to get familiar with the device.

By the way, I just did a quick search looking for the motor controller you mentioned but I don't see it supports CAN communication.

Regards,

Enrique

Thanks for your reply, Enrique.

The motor controller supports 4 CAN protocols. One is the standard CANOpen, the other 3 are simple proprietary protocols. The most basic is what is called RawCAN and it lets you build CAN frames. MiniCAN is another simple protocol which may be able to exchange with.

I wonder if you could shed any light on how to set up the CAN-BUS connection for testing. I've already seen the code example given in HalcoGen. But there might be some problem with my connection set-up.

Thanks,

Zhuhan

Hello:

Take a look at this post:

This post provide some information about DCAN module. Also, there is a CANOpen stack available from an external company.
