Hi all ! On another thread (cheat sheet thread), I have explain I use launchpad for driving a SI570. some of you have need I share my work. it's ok... ;-) look attachment file. For understand my work, i preconise to read the datasheet. The SI570 have 2 mode for change frequency, i use the "long" mode. I recalc all parameters in every change frequency.

(I think attiny/softrock already uses this trick.) but, I have 2 problems (in Fxtal
