PIC18F4550 Programmer

PIC18F4550 ICSP JDM programmer using PICPgm

The JDM programmer is cheap and easy to use and build programmer which uses PC serial port (COM port). This programmer can program many types of PIC microcontrollers like PIC16F84A and PIC16F877A and many others. The circuit and software of programming PIC16F84A and PIC16F877A are on the following two links respectively:

PIC16F84A Programmer

PIC16F877A Programmer

In this topic we are going to see how to program PIC18F4550 using JDM programmer.
The software used to program the PIC18F4550 is called PICPgm it is a free and simple software. PICPgm has the ability of detecting the programmer board as well as the PIC device and uses the appropriate programming method.
For the JDM programmer and PICPgm no external power is needed.
PICPgm can be downloaded from the following link:
The JDM programmer circuit schematic connected with PIC18F4550 microcontroller is shown in the following image:
