PWM-Signal
PostPosted: Sun Oct 06, 2013 1:02 pm     Reply with quote
Hallo

I have a problem to generate a PWM-signal...
I want that a LED is dimmed by a PWM-signal. I know that there are simpler methods but I will learn how I can use a PWM.
I use the dsPIC33FJ256MC710A, the PCD compiler from CCS and the dsPICDEM MCLV development board.

I don't have the PCD compiler but since no one else is answering, I'll try
to help you.

Look in the PCD compiler manual to find a commonly used PWM function
for a dsPIC33 with Motor Control PWM, such as set_motor_pwm_duty().
Then do a forum search for that, and all Motor Control dsPIC33's:
Quote:
dsPIC33FJ*MC* set_motor_pwm_duty

Set it to Search For All Terms.

Then you get this hit, with example code at the end:

Next search for this:
Quote:
LED pwm dim*

and set it for Search For All Terms. Then you get an example for a 16F
PIC, but you can use the basic idea to make code for a dsPIC33:
