what is the chance that you can send me the PCB layout you used... Will save me a lot of work... :)
Have looked around and found a sweet double sided board, but my meager workshop does not cater for that...
Nice job and hope to see some new goodies from you soon...

Giorgos has done a fantastic tutorial on the PIC, well worth a read
Failing that a google search on "pic16f628 configuration settings" will bring all you need.

i was making this up on a mikroelektronika EasyPic4 Board..
i have PicKit 3 if you think this is better..
i am in need of configuration settings for the pic16f628 chip for programming..
thank you for your time and patience

I used the PICkit 2, v2.61 to program, (using a clone board)
Hope this helps

i have made this up and i am having problems finding settings for programming options, i to am using pic16f628a version, i understand it's low voltage programming option with this..
please let me know your programming settings, i really would like to finish this project..

Hi Ron, I did try but zero cal button does not work ?

What hardware did you use to program the chip? Ive tried a pic kit 2 and 3 and I'm not having any success :(

Can we use a 16F628A instead of the older 16F628?

Hi, thank you for the project. Where are the hex files? I don't find it.

Nice work Ron!!!! Thanks for sharing your project.Also nice work with the pcb exposure and the box you drilled...

In your video, you measure 2 twisted wires. Those two twisted wires gave me a headache some time ago when i was experimenting with the capacitance touch buttons. I was using a 2-side PCB for sensor connected on the breadboard with 2 twisted wires... According to my calculations, the capacitance had to be very small, but in fact the PIC had a different opinion and measured almost double the expected capacitance. It was the stray capacitance of the 2 twisted wires :)
HOT in heaven!
