This project was awesome!! first i try to build it on universal pcb board, i works then.. the internal Vreg was blew up, it warms then suddenly the Vusb pin died, cannot connect to usb. The usb communication failed. After do some research, i read the datasheet of 18F2550 and i can use external power to my vdd (Vusb is >= vdd) rail it says. So make story short i put 330uh, 1k resistor and disable the Vreg bit off on fuse and it works. Now i finally use my programmer!! tnx!! i wish for update is support atmega series like atmge2560 and so on!!
Awesome programmer i built it on a perfboard it works like a charm. It brought all my PICs and AVRs back to life :)
Look nice thanks. Keep it up!
Nice and Easy to use.
I am trying to learn how to program PIC's and have been looking for a programmer that I could build for a low cost, work reliably, support newer chips, and work with different brands of devices. This project meets and exceeds all my requirements. I was able to follow the instructions and on my first attempt succeeded in making a working programmer that is modular in design. I now have a much better programmer than the one I had been fighting with up to this point. A lot of thought and effort has been put into this project and I appreciate the high quality results very much!
