OS Windows 7 Professional 64bit[...]Am I missing something or using the wrong ISP Programmer?
Do you see both COM ports in your device manager when you connect the programmer?
Power supply for mcu 9v battery....AVR Studio says to check my power supply.Pololu config editor says VDD went low so programming was aborted.
QuotePower supply for mcu 9v battery....AVR Studio says to check my power supply.Pololu config editor says VDD went low so programming was aborted.Theres your problem. Measure the voltage while trying to program - my bet is it drops too low.
Hmmmm another thought . . . I remember several people posting in the past that they accidentally inverted the ISP header connections and took several days to notice . . .
Did you ever try changing the Com port number in windows? It could be a resource conflict. Does the LED start flashing orange when connected to the computer and powered MCU? Or is it stay flashing red?
I'm glad this wasn't a problem with the Pololu programmer, (or at least completly the programmer) as I have been trying to push the programmer around here as a cheaper alternative with more features compared to a 'official' AVR programmer. It works flawlessly for me Axon 1 and 2, on a laptop with win 7 64 bit.
