Hi,
All this talk about crystals got me thinking about a cheap way to make a external oscillator for the Tiny13.... The only thing bad about this part is that it can not drive a crystal to make serial comms possible :-( Nothing can be perfect....
Does anyone have a handy, small and cheap crystal oscillator circuit that is reliable and uses low power ??? If it could use a resonator even better.... It gets cheaper and is good enough for serial communications...
