JDM - A Simple PIC Programmer Circuit

Views:

The JDM programmer is one of the simplest PIC programmers available. The design comes from the excellent JDM low cost programmer. It connects direct to the PC serial port using Windows driver software IC-Prog for easy programming. No external power supply is required and a simple board layout is given requiring no special PCB manufacture. Note that the design is limited to the PIC series (12F, 16F and 18F) of chips and cannot be used for In System Programming - ISP.
If you need a more advanced programmer then try WinPic800.

The JDM circuit connects to the computers serial port through a DB9F female connector and the LED are optional but are very useful particularly when testing the circuit.

By connecting below two circuits together, you can able to get a complete JDM programmer for program all pic series.

Hardware Testing

  1. Connect the programmer to the PC serial port using the Female to Male serial lead
  2. Start the IC-Prog software and under 'Settings -Hardware' select JDM Programmer
  3. Insert the PIC into the programming socket
