Jdm Programmer Circuit Diagram. For a list of all pics supported by picpgm software can be found here. 5 circuit diagram of modified programmer.
The programmer is powered from the serial port itself so theres no need to any external power supply. But be careful this circuit will not work with the laptop serial port due to. My main goal is get the jdm serial programmer working with the pics.
Below are chip placement diagrams for common chips from 8 pin.
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. The programmer is powered from the serial port itself so theres no need to any external power supply. There are a lot of informations about programmers look an microcontrollers selection. 5 circuit diagram of modified programmer.
