    Sorry. I did post a link to the datasheet. The exact chip is a PIC16F627. The datasheet doesnt mention ADCON anywhere so i assume it doesnt have it. Ive tried setting CMCON. I took a look again at the datasheet and tried a few values. Ive now found one that seems to work properly. From what i can see, all of porta is working as expected now.

    While testing ALL pins ive noticed another problem. RB0 wont turn off. Im sure this is because its a special pin but i cant see what to do with it.

    In that first link RA4 isnt a problem because its an input anyway.

    Ive attached the full code so far as requested. Everything seems to work except RB0

    HAHA. I found the problem. When i set all the pins low i put "portb.2" instead of "portb.0".

    Everythings working now The circuit can control mains bulbs and/or LEDs with brightness control.

    Im sure your all thinking "THANK GOD. Finally". I would like to thank everyone who has helped me with this. It looked really simple when i first started but if it wasnt for the people on this forum i would be hitting my head on the table right now.

    Ive just got a few bits of code to add and cleanup then it should be done but im sure i can handle those myself
