how to create PWM signal using c programming. I am beginner in c programming i have no idea in creating PWM using c programming for my ezdsp.Can anyone suggest a method to create and what type of coding will suitable for this PWM pulse. Cause if i am not mistaken then C programming cant involve much in graph.

What does your ezdsp suggest as the way for you to create your PWM signals? If it requires PWM signals, it should give you at least a hint of where to easily get suitable one's.
the suggest for ezdsp are C/C++ programming
And what ELSE does it say?
No sample program, no pseudo code, no skeleton code, no nothing? I just have that strong feeling that you're not sharing all the relevant info on this.

Did you try Google, I found this link on the first page when searching for "ezdsp f2808 PWM" http://www.ii.pw.edu.pl/kowalski/dsp...e/PWM_DEMO.pdf
Or you could try to read the manual http://focus.ti.com.cn/cn/lit/ds/sym...ms320c2801.pdf

You can probably configure a hardware timer to output PWM. Read the datasheet on how to do that.
If I do not see more effort soon by the OP I am going to close this thread.
Actually i am working on BLDC motor controlling. this motor requires 3 phase inverter and the particular inverter needs 2 output to be high at a particular moment. the PWM that i need to obtain should be as in this pdf http://www.st.com/stonline/books/pdf/docs/10691.pdf.... the problem is the method of creating this PWM i am unable to understand cause i studied this C programming few years back and when i search for the method of doing the PWM for this BLDC motor is seems hard.
Let Google be your friend. "software for a PWM for 3-PHASE BLDC MOTOR DRIVES"
I found the following link although for a different processor seems to have a good explanation of how to drive a 3 phase brushless motor with PWM. http://www.freescale.com/files/dsp/d...ote/AN1961.pdf
