Hello everyone,,,
I am trying to program AVR ATMEGA32 using parallel port,,,
so I used the schematics in the attached gif file, and the software is Ponyprog2000.
I chose the interface setup to be AVR ISP IO from LPT1, and i clicked the calibration button. Then I chose ATmega32 from the device menu.
up to now everything went well, except when I tried to write or erase hex data it gave me the messege: " Device missing or uknown Device (-24)"
I replaced 3 AVR's and 4 74HC244 drivers but nothing changed.
Maybe I am missing something, The 10 pin connector is connected directly to the AVR and the crystal frequency is 10 MHz.
I appreciate your help guys because I am stuck!!
Thanks
