many thanks for the insights!
I allready visited preferences.txt to set the clock speed of my board I'm currently using this board: Microcontroller Modules, Boards, Tools and Accessories for Atmel AVR ATmega Xmega Processors.
But it's so tiny and well done that I will post a whole thread about it
Somehow I didn't really notice build.mcu=atmega8. That's great! I mean, can we allready just use other AVRs? Well, I guess, only if one won't use timers etc. I will check this with my atmega128 board as soon as I get it back from a friend.
Just the next feaure request: To use different boards with different hardware side by side, it would be required to store hardware preferences like the board clock etc. in the sketch file itself...
I mailed massimo some weeks ago about helping with developing, as he called for it on the webpage. I'm still interested in taking part of arduino development.
I noticed F_CPU is not really beeing used everywhere (delaymicrseconds() etc.). I'll focus on getting arduino clock indepent for a start, as I need it anyways (I'm running on 14,7456Mhz)
