PWM Generation using f28335

Saifuzzaman Sabuj

Dear All

I am a new user of f28335. I am using code composer studio v3 to program f28335 processor. I want to generate a simple pwm signal which can be observed by using oscilloscope. Probable, DAC is needed for this purposes.

Could any one give an idea or existing program ?

thanks

Saifuzzaman,

Attached to this post are CCSv3.3 projects that generate PWM on F28335. It goes with appnote SPRA958, but the web version of the appnote no longer supports CCSv3. This code is from an old version of the appnote. Download and browse the appnote, particular the part towards the end that describes the code. The appnote topic itself concerns running from flash which isn't your issue right now. But the code is good starter code for you. The appnote is here:

Also, CCSv3.3 is pretty old. I know you're using it for some reason, whatever that may be. But think about upgrading to CCSv5.

Regards,

David
