I am planning to build a project, but it's something quite embedded and I have no need for the extra features or bootloader of a standard Arduino. At the same time, I think I want to use the ATmega 328P rather than an ATTiny, which is what I'm familiar with for this.
I'm running into confusion with the boot size bits and I'm not too sure about the clock setup bits either (normally I run an ATTiny with internal clock). I'm fairly sure I bought some 16MHz crystals and capacitors for this sort of thing a while back, but I'm also sure there will be times that the internal crystal will be fine.
Does anyone have a favored fuse config for this?
I am using an external programmer over the six-pin SPI/ISP port (well, the pins that would be the equivalent of that) for a "boarduino." I only care about the power filtering and external clock (in cases where I need the latter). I'm not bothering with auto-reset or UART since, again, I'm using a programmer.
I would appreciate both configs for 16 MHz (most Arduino-like, I believe) and internal clock at 8MHz. Thanks!
Edit: Here are my settings so far: http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=FF&HIGH=D6&EXTENDED=FF&LOCKBIT=FF. I think that's normal for a "regular" Arduino (minus some stuff I may have messed up in the high fuse) but I'd like to not bother with any bootloader stuff and have my code run right away.
For the internal clock version I have this so far: http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=E2&HIGH=D6&EXTENDED=FF&LOCKBIT=FF
