PIC16F84A Programmer

Program PIC16F84A using JDM programmer

It is easy to program a pic microcontroller using com serial port. The programmer is small and easy to build and also very cheap. The ICSP (In Circuit Serial Programming) allows you to program your chip without removing it from the circuit. The following schematic diagram shows the programmer of the PIC16F84A using PC com serial port:


The software used to program this pic microcontroller is ICPROG and the following pictures shows its configuration:








Sometimes you have to remove the crystal oscillator because it may affect on the chip timing, therefor verification after programing will be failed.
