Making a Simple PIC Programmer.

In this tutorial we will make a simple serial port based programmer for PIC microcontrollers. I have tried several easy to make programmers and software, and here I a presenting the programmer that worked the best. The design is based on JDM. The software we will use is PICPgm by Christian Stadler. I liked the performance of the software, its fast and easy to use. The programmer will make uses the COM port of Computer for communication. Components required. S.No Item Value/Part No Qty 01 Transistor BC337-40 or BC337-25 2 02 Capacitor Electrolytic 100uF 16VDC 2 03 Zener Diode 5.1v 0.5Watt 1 04 Zener Diode 6.2v 0.5Watt 1 05 Diode 1N4148 4 06 Resistor 1.5K 1 07 Resistor 10K 1 08 LED RED Colour 1 09 DB9 Female Connector with Cover – 1 10 6 PIN Female Connector with Wire – 1 11 Veroboard, Wires etc – - Circuit Diagram Now assemble the circuit as shown below in a piece of veroboard. Fig. : Simple Serial Port Based PIC Programmer. So our PIC programmer will have two interface A Serial Interface for Connecting it with PC A 6 PIN ICSP Connecter – This will be connected to our PIC which will sit in our project (say in a Breadboard).
