Hi,
I have been trying to program a ATTINY84 over ISP with an Arduino Uno. Whenever I try to upload the Blink sketch I get this error message. "avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
An error occurred while uploading the sketch"
I don't know if this is a problem with the computer, the Uno, or the ATTINY.
Thanks,
Ben

Re: Problem using ArduinioISP to program ATTINY84
What are you using as the build target under Tools->Board?

Re: Problem using ArduinioISP to program ATTINY84
You might want to try one of the higher clock rates. By default, the ATtiny84's clock runs at up to 10MHz from a 3.3v supply and 20MHz from a 5v supply.
The 1MHz rate is a low-power mode that might require some fuse settings. I'm not sure really.. that isn't a chip we use.
