Hi all,

i tried to program an attiny85 20mhz, and i receive the error message :

avrdude: stk500_getsync(): not in sync: resp=0x00

I followed this tutorial :

Can you help me ?

Hi

Reading the linked tutorial i only see support for the 1MHz or 8MHz internal clock sources on the ATTiny85.    What instructions were you reading for 20MHz? 

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.

What did you do, exactly?

And what are you using to do it?
No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

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?
