Problem PWM half bridge with 20khz and 40khz output synchron

[lucasromeiro]

I have a problem to program a PIC16F616 generating a PWM half bridge with 20khz and 40khz output synchronized with that pwm on pin 3. I managed to turn the half bridge on for normal use. But this output could not activate. I know you can have as it is a synchronization module ccp. So it is always twice the half bridge. I know a manufacturer of amplifiers using this configuration but as usual the code is restricted. Forgot to mention that I am using the internal clock.

HELP!

care to post the code you have ??

no way to know what is wrong w/o it

if setup right - the PWM divisors and master Fosc should line up ok.

also what do YOU mean by synchronized?
as in both PWM signal transitions relatively aligned on zero cross
now and then ??

or something else entirely?
