Yes, it sure would help if I used the right chip :-)... I think I'm loosing it! lol.

I'll head on over to my parts supplier today and "PIC UP" the right chip.

I had the PIC16F628A from an other similar project that never worked and I had though for some reason that you were using the same chip for this project - I really need to read things more closley.

Which pins output the serial data? I tried pin 6 (I thought thats what it said in your code, But I wasn't sure) but didn't get any output. I just used an LED to try and detect output to make sure the circuit was working before thickining the soup by trying to connect to to my PC, yet. I did try presenting a standard Weigand Prox card with with no luck.

How do you read the calibration data?

Sorry to have to ask so many questions, but I am very new to this.

Thanks so much,

James.
