Pwm

Is there anyway you can PWM to pins at the same time?

You can, if you use a PIC with two hardware PWM modules.

Or, you you use interrupts. Search for Darryl Taylor's "instant interrupt", and you'll find everything you need. (I think a post from just today has it.)

Hi XOXB,

Yes I agree that Darrel's Multiple Slow Speed PWM example is great. I use 16 channels of PWM to control the brightness of LEDs on an 18F2410. I believe you could do 8 or more on a 16F. It all depends on the freq and the resolution you run at. You must use this with DT_INTS-14 or DT_INTS-18 depending on the pic.

Thanks again Darrel!!!

Do they need to be at the same frequency?

Are the duty cycles related (e.g., 1/2 or double of the other)?
