In the old days it was very simple to use the parallel port of a standard PC and program just about any type of AVR microcontroller with it. When you want to do that now, you`re first obliged to buy aprogrammer that communicates with the PC via USB, which....

This is a "beta release" schematic. Use at your own risk The idea is to add this circuitry to a board with already has ram at 2000 and an 82C55 I/O chip to provide ports A, B and C. Warning: not shown here is a memory mapping trick which is described below.....

This JDM programmer works with a RS232, 9-pin(9 wire) DB9 Serial connector on your computer, and is used for loading Source Code (hex files) into your microcontroller. JDM programmers are Cheap and very easy to make. JDM programmer that we are going to make....

This Arduino sketch is useful for rescuing ATtiny microcontrollers rendered useless by incorrect fuse settings. It does this by putting the bricked tiny into high-voltage serial programming mode and writingthe fuses to safe values. The Arduino is connected....

Programmer in my "AVR software and technical Library - April 2003" CD-rom and decide to publish it. The reason was, that this programmer is very stable and works perfect with AVR Studio 4. I hadtested it before published it, with AT90s2313 and its worked....

This simple circuit can be used to program the PIC16F84 and similar "flash memory" type parts. It uses a cheap 555 timer IC to generate the programming voltage from a +5V rail, allowing the circuit to be powered from a computer`s USB port. The 555 timer....
