Because I think there is a big lack of knowledge of the new ATtiny 1 series and 0 series about in topics likes timers (TCA, TCB , TCD) ,ADC , DAC,TWI...etc. I saw recently that MC has updated some application notes on "How to get started", I thought its a good idea to post the links here so it can help beginners to look up for these notes themselves and after that if there is any questions they can share it in freaks, the notes has has some basic source codes that can be adapted to any mcu from tiny 1 and tiny 0 series.
so here it is:
These are just links to the Appnotes, so its just a copy/paste. I posted it here because i noticed many of the new attiny users overlook these notes which might be helpful, althought i havent tested the whole source codes but so far it all compiled. with small changes you can also adapt it to any part in the tiny 1 & 0 series.
