How to link DSP with Matlab

Yang Lu99085

Hi,

I'm working on an control problem using EVM6678L and Matlab. My CCS is versioini 5.0.3 and my Matlab is version 7.0.

My control object is built in Simulink, and the control input is calculated by DSP. What I want is, each step after the control input is calculated by DSP, it is sent to Simulink and exerted on the control object. Can anybody tell me how to establish a link between DSP and Matlab to implement their cooperation? Better with some simple example to illustrate.

Regards,

Yang

Hello Yang,

The last CCS version to have full debugger integration with Matlab was CCSv3. For CCSv4 and v5, it is more limited:

There are plans to support this but I am not sure of the schedule.

Several people have been able to access the CCSv4/5 debugger from matlab by leveraging DSS. If you search the forums for "matlab DSS" (or something similar), you should see some more information.

Thanks

Hi Ki,

Thank you for your respond! Along with the EVM there is a RS-232 serial cable. So can I just use the on-board serial port to make a connection with Matlab? I have learned that Matlab can do serial port communicatioin.

Regards,

Yang

To use CCS/DSS, you will need to use JTAG connection.

Hi Ki,

Is it that JTAG is necessary for connection between CCS and Matlab?

Hi Ki,

My board is EVM6678L and I have USB cable, Ethernet cable and RS-232 serial cable. Can I just use one of them to connect to Matlab? Currently I don't have an extra JTAG.

Regards,

Yang

If you wish to get CCS debug access to the target, then yes.

If your EVM6678L has a mezzanine card with the on-board XDS560 emulation, you can use that by simply connecting to the USB port on the mezzanine card. Otherwise you will need to connect via JTAG
