Hi all! I have found on the net some schematics for "A serial programmer for PIC16C84" including software (c-language) and I tried it out! It works! With minimal costs! --> Does anybody know which types of eeprom-PICS can be programmed serially? --> Can I alter my selfmade programmer to program other PICS than PIC16c84 without bying an expensive programmer?
