Need your help for a newbie
Hello all ;
i dont know english at all but really need help on this so that i asked a friend to translate it to English and ask for your help :)
i want to make an ADC and HPWM application with 18f4520 .i've done many tries but never succeed , i think its something about my config file or basic knowledge about it. Thing is; if value on ADC when i pressed the buttn conneted to Portd.0 is between 50 and 300 , i want to get 10 khz hpwm from CCP1 and CCp2 .. İf its less then 50 and more than 300 there wont be any signal.
Here is my config file amd codes , i know i m a rookie but every little thing is a start , thanks for your time and upcoming help :)

It might help to know what PIC and version of PBP you are using.
I never did PWM but I see a few things:
1. That is not a correct CONFIG statement (chech PBP manual).
2. Move TRIS before HPWM statements.
3. Add ENDIF to IF statements (check PBP manual).
4. Missing a space in HPWM2,0,0.
Do not use political hash strings in thread titles.

Re: Need your help for a newbie
its version 4.0 with PIc 18f4520
i also corrected 2,3 and 4 but not sure but not able to find something about CONFIG statements on manual and no idea how should CONFIG statements should be :(
btw sorry about hastags , i normally do not put things like that but since its not a political issue , it seem to be no problem but rules are rules , i respect to that ...
Re: Need your help for a newbie
Can you show me a link to where you got PBP version 4?
