Which do you use when working with ATtiny processors?  The internal oscillator at 1 MHz?  At 8 MHz?  Or an external crystal at 16 MHz?

The internal oscillator at 8mhz.

Ro-Bot-X

Internal, 8MHz. At least, that's what I'm planning to use.

You forgot: external clock sources and resonators.

Have you used either / both?

Which resonator frequency?

Udo Klein

I have used 8 MHz resonator. External clock is needed for use with external osciallators, I have several of them around. 1,4,8,10,16 MHz.

Three new choices just for you Udo.   ;)

Udo Klein

Now I voted :)

I wonder why so many people use 8Mhz, I use CKDIV in order to lower the admissible supply voltage, thus I have to run at 1MHz (or lower).

I use 8 MHz while I'm developing but I honestly I have no idea why.

You can definately squeeze more out of a battery at lower clock frequencies.  I switch to 1 MHz for final testing and deployment.
