320F28335 Motor Driving Problem

Hi all,

I'm studying on quadrotor. I'm using TI 320f28335 Starter Kit and CCS v.3.3. I'm trying to get PWM signals and driving motor with these signals. But I have problem.

I setted up CCS v3.3 which comes with box of starter kit. When I run the ccs I couldn't get the PWM signals. I did all requirements, everything. When I try same code in ccs v4 I can get PWM signals but because of it breaks usb connection while working I do not want to use version 4. But another hand, working code does not give any result in ccs v3.3. I have some suggestions to upgrade my ccs properties to these, Version 3.3.59.4 - Integrated Development 5.98.0.339 - BIOS 5.32. But there is no any ccs v3 available download link.


What sholud I do? Thanks...

    I would definitely say that since CCS3.3 is quite old it would be advisable to update to CCSv4 or preferably v5. I don't know what you mean when you say that CCSv4 "breaks usb connection while working". In any case, you could make sure you are on the latest version of CCS3.3 and give it a try again. The last service release for CCS 3.3 was SR12 (version 3.3.82.13). If you registered your copy of CCS, you should be able to get the updates from Update Advisor (by going to CCS menu Help->Update Advisor).

    If you wish to try a newer version of CCSv4 or v5, they are available for download from http://processors.wiki.ti.com/index.php/Download_CCS

    In using Ccs v3.3 as you say I think I must upgrade the version so I will try your your "update advisor" suggestion. 

    Generally my problem is that, I have matlab-simulink output codes which runs truely. In v3.3. when I loaded the code and I  run, it does not give any result. Otherhand, in v4. I can get pwm results but when I did motor connection and I run usb connection disconnects and then I could not get any signal from eZdsp kit's port which I got pwm signal, I think it harms and becomes not usefull! 

    I have shocked what should I do. One hand, true connections no result (v3.3), other hand false connections yes result (v.4).

    Thanks
