Fuse bit settings not documented

[hanshuebner]

Sorry to bother again: Can you share the correct fuse bit settings for the device?

I did not make special requirements in this regard to make the software work with any arduino compatible device.

When I designed my board, I could not get an Atmega328P, but only the slightly different Atmega328PB in the necessary package size. This gave me a bit of extra trouble because the chip ID is different and the flashing software did not work. I can not remember how I overcame this problem, but in the end it worked somehow.
By using the "normal" Atmega328P this should be easier as there is very good support in the arduino system for such bar-bones setups.

You need configure it to use the internal oscillator at 8Mhz.
