HELP! please rc=-1
I am relatively new to the electronics world, but I have completed several small projects
I am using the usbtiny from a kit.
I am running windows 7 64bit
using avrdude 5.1 to program and Atmega32a or m32
this is my first time trying to talk to a chip
basically what is happening when i try to program the circuit diagram in a picture bellow all I get is an "rc=-1" error message, when i use the
-F command to override it I get the same error, and it says the device signature is "0x000000"
this is for an led cube, i am using professionally printed parts, and this design has been confirmed as working by atleast 15 people i have spoken to, I have no idea what is going on so any help is greatly appreciated.
also this has been looked over by my electronics teacher at school and he had no idea either
Thanks very much
