I have been looking in to programming the ATMega328 on the Gertboard with Adafruits USBtinyISP.
As it has a levelshifter in the signalpath it can be powered through the target system.
This way the 3.3V chip on the Gertboard can be programmed from the 5V USB connection.
That's the idea anyway.
I've tried connecting powering the ATMega328 chip with the 3.3V from the Raspberry Pi through J7,
but all it does is lighting up the LEDs on the Gertboard.
My goal is to program this AVR chip independently of the RPi through avr-gcc and avrdude from my
laptop.
Any suggestions as to how this can be done?
EDIT: accidental dublicate of ISP for AtMega328 on Gertboard
