Datasheet

If you are using the avrdude in the Arduino IDE, you'll need to use bin\avrdude -C

etc\avrdude.conf -c ftdifriend -P \\.\COMxx -p atmega328p etc.

Once you have the hashbar show up nicely, that means you are talking to the chip all right.

Yay! You can now program the chip using the -U flash:w: command.

Press the up arrow to get back the command you wrote and tack onto the end a -U

flash:w:firmware.hex (where firmware.hex is the hex file you want to burn in) For

example, if you want to burn a bootloader on, make it easy on yourself by copying the file

from use:

bin\avrdude.exe -C etc\avrdude.conf -c ftdifriend -P \\.\COM46 -p atmega328p -U

flash:w:..\..\arduino\bootloaders\atmega\ATmegaBOOT_168_atmega328.hex

(you can also copy your file to C:\ so its not so long to type. Hit return and grab a beer, it'll

take about 5 minutes per byte of data you want to write&verify)
