Hi OldSteve
Well I've taken the plunge and downloaded and installed ATtiny Universal. If I select Tools in the Arduino IDE there are few more options than the older ATtiny Microcontrollers. I've naturally read the README document but it makes no mention of what the following do.
Board: Obviously what flavour of ATtiny you have.
Timer 1 Clock: Timer interrupts? Related to clock?
B.O.D.: Brown Out Detection? So what happens here exactly? If VCC reaches 4.3V for example the chip restarts?
Clock: Simply speed of processor? Any correlation to Timer 1 Clock?
Chip: Obviously related to choice made in Board.
I know I may sound like a broken record but I do appreciate your help.
Cheers
Jase
