i need a simple programmer for the atmel at90s1200 MCU .
i already made one but cann't program the device with ic-prog 105D having this
message "no acknowledge received" , changing to ic-prog 105A programmed the
chip but failed to verify it .
regards ,
i measured the vcc & found it 3.238 volts , is it enough to complete the process ?
the programmer's schematic is as the image, & i configure it with ic-prog as funcard programmer .
Regards,
Hi amr_electron, that programmer which you show in your above picture I use to programming AT90S2313 and it works very good, if you use winXp did you know that you must enable NT/200/XP driver in IC-Prog ? More information you can find here https://www.serasidis.gr/circuits/avrprog/avrprog.htm

i really got the design from this page & i use WINXP with ic-prog driver enabled, i checked my board twice & it has no mistakes, but still not working .
