I've bought some of these ATMEGA328 prototype boards
http://www.makershed.com/ProductDetails ... ode=MKSKL4.
Due to the fact that I need to interface this to 3.3V logic, I need to change the regulator on this board
to a 3.3V regulator.
The data sheet for the ATMEGA328 shows that I need to lower the clock so the chip will be in the safe zone.
Since the ATMEGA328 has an internal 8MHZ oscillator, I think it makes perfect sense to use it,
since my project does not need to run very fast.
I was told that I need to change the bootloader if I change the clock.
Would someone point me to information on..
1. How do I configure the 328 to run using the built in 8MHZ oscillator?
3. How do I change the bootloader?
2. Where do I get the code to change the bootloader?
thanks in advance
