I'm a hobbyist, I wanted to create something with a GPS and a SD card, I found this project in internet:
It includes the code and schematics.
I was trying to load the code to the ATMEGA644 but I have not been able to do it. I'm using AVR Studio, and I set up the STK to isp, but I always have FALING messages when I try to upload the code.
I would really appreciate if you guys could tell me like some main steps to program the chip.
