Hi,

That implies one needs to set the Duty Cycle to 80 to get a 4uS On / 4uS Off square wave?
(This does not make sense to me.)

Thanks,

Ioannis,

Thanks for the feedback!

I have been using the attached calculator from Mister E.

I found this:

Which produces this:

PR2 = 0b00001001 ;
T2CON = 0b00000101 ;
CCPR1L = 0b00000100 ;
CCP1CON =...
