i tried to program an attiny85 20mhz, and i receive the error message :
I bought the attiny85 20mhz, tried to program them by following exactly the tutorial... and i have the error message...
Oh, sorry my mistake.That error means there is no response coming back from the ATTiny. Do you have the resistor or capacitor in place (depending on what arduino you are programming with)?Did you get past the 'burning the boot loader' step okay, or is that where you are getting the error?Geoff
I bought the attiny85 20mhz, tried to program them by following exactly the tutorial...
The arduino-tiny cores support 16MHz with an external crystal. I've read discussions of driving them faster but cannot recall whether arduino code was being used.
The attiny85 can go up to 16MHz without an external xtal. The maximum 20MHz requires an external xtal, though.Its just a matter of selecting the clocking fuse values appropriately. I run my attiny85 chips routinely at 16MHz, sometimes (more often than not, actually) even at 3.3V (shock horror! )
