hello anyone,
i have just purchased 4 ATMEGA324PA from element14 (my.element14.com) and i have DT-HIQ USB ISP AVR to program my device...when i try to read the chip signature using that programmer and my new codevisionAVR (version 2.05.0), i always get error message "AVRISP error leaving programming mode" and it all occurs on all of my ATMEGA324PA, but when i replace my ATMEGA324PA with my ATMEGA16A on my circuit board (my own design) and do the same thing again, it works without problems...btw i have checked and ensured that there is no problem with my circuit board (since it works well with my ATMEGA16A) so i think the problem maybe comes from my ATMEGA324PA or my DT-HIQ programmer...btw do you know how to solve this problem? doesn't my DT-HIQ support my mcu that i've just bought or is it my mcu that is broken already??
btw thx for your response :)
