Serial Port - Event Driven Programming Problem
Usually there's an USART interrupt handler that puts incoming data into a small cyclic buffer. The main program loop would normally check if there's incoming data and handle it...

ADC and timing
I had no idea. Live and learn!

ADC and timing
Weird, it seems to be 48,88.. specific. What is the point of this register and how other AVR's manage without one?

DIDR0 = (1 << ADC5D); //turn off the digital driver What is this register? Some alias for DDR(A/B/C)? I can't find anything like this in the datasheet.

Collaborative File Management?
I'm learning to use Hg in the meantime and I learned that while it's cool to be able to run it as a server, it's equally cool that you can export all changes from one repository...

scan files with FatFs from Chan
I can't be 100% sure, but I think the version I used had no concept of "current directory". This was a couple years ago and I used the most stripped down version, too. Things...

Fade LED using timers only
Unless you want me to read the datasheet for you, here's a hint: find the table with BOTTOM and TOP values in each mode, check what is used as BOTTOM and TOP in the mode you chose...

You need to setup a timer compare match interrupt and use it instead of "if (TCNT0 > cik)...".

Your subjectively correct reading may be a product of multiple errors =)

ADC and timing
ADCSRA |= (1 << ADSC); ADC_dummy = ADC; You start conversion but you don't wait for it to complete. You should either use an ADC interrupt, or wait until (ADCSRA &...

"/" would be the root directory. Probably an empty string will work just as well.
