Atmega328p standalone

Very simple and basic setup with Raspberry Pi 2 SPI programming. Try at your own risk.

Linux setup for SPI:


/etc/avrdude.conf:
programmer
 id = "linuxspi";
 desc = "Use Linux SPI device in /dev/spidev*";
 type = "linuxspi";
 reset = 25; #this is opposite of SPI ports on the RPI
# baudrate=400000; # this is too high for my atmega ...
 baudrate=100000;
;

avrdude transfer and fuses:
sudo avrdude -p m328p -c linuxspi -P /dev/spidev0.0 -U flash:w:build-cli/MYBUILD.hex
sudo avrdude -p m328p -c linuxspi -P /dev/spidev0.0 -U lfuse:w:0xFF:m -U hfuse:w:0xDE:m -U efuse:w:0x05:m
