Setting up the ATMega328 chip
Plug the USBTiny Programmer into the AVR-ISP 6 pin header J7. Using AVRDUDE Validate the USBTiny is communicating with the Power Fail Module Microcontroller avrdude -c usbtiny -p m328p -v The Microcontroller is set to 1HMz and needs to be changed to 16 MHz Default Using AVRDude enter the follow command to set the fuse bits on the Microcontroller. avrdude -p m328p -c usbtiny -v -U lfuse:w:0xFF:m -U hfuse:w:0xDE:m -U efuse:w:0xFF:m Make sure it matches these settings: avrdude: safemode: hfuse reads as DE avrdude: safemode: efuse reads as FF avrdude: safemode: Fuses OK (E:FF, H:DE, L:FF) avrdude done. Thank you. For more information about using AVRDude refer back to this link ==AVRDUDE Class==
