FRDM-K22F AtoD Value passed to PWM

Hi All,

I wrote a program that will take an AtoD measurement that I would like to pass to the PWM to set the duty cycle.

Can someone look at my code (very small) and let me know where I'm going wrong? Note: I removed my LED code so it's not so large to read.

Thanks,

Brian

Hi All,

I found the solution to my problem. I wasn't including AD0_Start(); in my program (see below).

What I left out in my description above was I'm using a Potentiometer that's connected to the AtoD pin.

Now when I adjust the pot the PWM changes as well.

Thanks,

Brian
