AVR isp

This ISP programmer circuit, based on AT90S1200 device.

I found the schematic of this 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 have test it before publish it, with AT90s2313 and its worked fine!!!

To work this programmer you must to connecta crystal 4MHz to slave device at the XTAL1 and XTAL2 pins, or if you have an device with internal oscillator (AT90S2343, ATmega161 etc) and its enabled , its not need any external oscillator.

If you want you can use MAX232 or MAX202 instead transistors, capacitors and resistors to connect master AT90S1200 with Personal Computer (PC). There is no problem (i check this hardware by using MAX202).

The software for this programmer (AVR prog 1.37)

More AVR devices ?

John Samperi made some modifications to the AVR910.asm file and create the AVR910_2313_v3.asm. This code can program more devices than AVR910.asm v2.2 does. The AVR prog 1.37 show all this devices. I dont know if realy program them with v3.0. All devices that ( maybe) can be programed by version 3 are:
