Can someone show me how to set ccp3 to RC6 on pic 18f24k22

Hello.
Yes I have been reading the data sheet and trying to understand how to do this but I don't really understand datasheets. Maybe if I can get this right I will help me understand them better.
Anyway. For now my hpwm 3,127,1000 command is appearing on port rb5. According to the data sheet it should default to RC6 but it isn't. I don't know why and I can't figure out how to change it.

Thanks

Hi,

Sorry I've been meaning to post the code I had for this, but have problems with the computer that has the file on.

The CCP3 output is set in the configuration bits, I'll have a look at the datasheet in a bit and give a better pointer.

EDIT: the joy of USB disks, found it!

Thanks for that. Actually I couldn't get your version to work but this does:
asm
config FOSC = INTIO67 , CCP2MX = PORTC1, CCP3MX = PORTC6
endasm

I think I have learned something and I am almost in danger of being able to understand data sheets. It's all in the mpasm pic inc file isn't it?

Yup!

Don't know what happend to the code i posted earlier in the thread, it seems to have been reformatted missing bits so would never work.

Here it is as an attachment

The top left icon above the post box has two As; click on it to get SOURCE mode. That will leave your code intact.

To have your post box in SOURCE mode by default:
- click on SETTINGS at top right.
- click on General Settings on left side.
- scroll down to Miscellaneous Options.
- click on Standard Editor - Extra formatting controls

Cheers Robert, It was going to be something simple.
