ATmega328p Anync mode timer init issue
And valid question: fuses setup. PB6 and PB7 also use as connectors to ex. cristal. If 32768 Hz cristal is connected -> no pins to connect external cristal left...

ATmega328p Anync mode timer init issue
My error in first place was that I use ext. 12MHz cristal and forget to set fuses on internal cristal while I connect 32768 Hz to chip.

Connect two mega's not by USART
I now look into some other chips. I don't know that ATmega1281 has 4 USART pins: 2 lines (RxD pin + TxD pin)... that is useful. That is perfectly match my tech spec. I...
