PWM setting PIC16F887

[skimask]

Hello,
I work on a application and need two hardware PWM outputs. One PWM (CCP1) to
control a DC motordriver LMD18200 (10 Khz) and one PWM (CCP2) for IR comm (38KHz)
The motor is still running, but runs on 1 KHZ. (I need 10KHz or maybe the same 38KHz as the IR Comm.)

Might help you out...

You can have different duty-cycles, but the frequency will be the same on both CCP1 & CCP2 since they both use the PR2 register of TIMER2 for the PWM period.

Hey...good point...Duh on my part...
Set up a 555 timer for a 50% 38Khz square and turn it on/off with a PIC pin, or use a 2nd PIC set up for the same thing as the 555. An 8-pin PIC makes a helluva useful 555 timer....with a load of options...
