Hwpw

RICHARD
I reloaded your program exactly and it gave me
12.54khz with a duty of 48.75 PW on channel A1
8.02khz with a duty of 49.61 on channel C2
10.02khz with a duty of 50.01 on channel B0

You were absolutely correct and it works perfectly
do you have any documentation of the settings and what to change for different freq and duty cycles Im just getting back into this after years of being away

RICHARD I need to change porta4 hwpw to another port i tried ccp3con and ccpr3l changed the ccptmrs0 but nothing works I have something else on a4 on the boards im using

or use MCC

if you need porta.4 for another purpose then you cannot use CCP5

post the code you have tried

first question how do you get the code box to post into


OK I was able to change the port from port a4 to port b5 now I need to figure out this

CCP4CON = $0C ; PWM MODE + DUTY LSB 2 BITS ' PORT B0
CCPR4L =%110010 ; DUTY MSB 8 BITS ' $32

it does not seem to be very straight forward I will look at the posts you sent yesterday and see if I'm able to do the math, shifting and what ever else it takes.
I did change the numbering to BIN so when looking in the manual I could line things up with the proper bits (don't get mad)
