Does anyone know of a good link on how to erase an atmega32 so that the arduino bootloader can be put onto it ?
and read off whats on it before erasure,
i have some old chips i would like to try and resuse, i have seen a link on supplying 12v to reset the fuses etc, was wondering if anyone can ellaborate on that
First the action of burning a bootloader will erase any prior sketch. As far as reading the contents of an existing sketch then using AVRDUDE in command line mode using a hardware ISP programmer will allow that and other tasks like reading/writing fuse bytes, etc.
