Hello,
how are you? I have a question about the GameBoy camera, did anybody interface it with PIC 16F877A and pic basic pro? I made a code for it but isn't working. I think I don't know how to set the registers so it can start to send me anolog voltage? Can anybody help me? I can show you the code if you want.
Thank you
Refik, I had some luck with a GB camera and an 8 bit pic. I got analog voltages out but never completed the project. Make sure your hardware is set up properly first. I remember needing one pin pulled up to 5 Vdc. Do you have a schematic of your circuit? I'll dig up my stuff if you want.

Dear Mike,
thank you for the reply. I used a PIC 16LF877A because of the intern A2D Converter. I connected the camera to the pic dirrectly without anything to pull up?!?
Can you send me your shematics, please? And one more question do I have to use another A2D converter because the one in the PIC is to slow? Every help is welcome :) Thank you Mike
Here is the code I used:
