Hi there! I'm having some troubles with my attiny85 and arduino uno. I'm using this for the attiny85 core http://code.google.com/p/arduino-tiny/
I've already uploaded the Arduino ISP sketch to the arduino Uno with no problems. After doing that the Board is defined as Attiny85 internal 8 MHz clock, programmer is Arduino as ISP.
The blink sketch is loaded and the led port is defined as 1. On the attiny the led is connected to port 0.
(I'm doing this because the led was blinking when uploading the sketch and I needed to know if it was the sketch running or some boot stuff -> it was boot stuff).
Now I tested the sketch upload with 2 methods:
1) Just connecting arduino uno and pressing Upload sketch button
2) Connecting arduino uno, holding reset and just when "Binary sketch..." shows in the console I let the reset go.
The two methods return different errors (at least in the video but i'm trying to reproduce it right now with no success).
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
I've tried a lot of things, I've read a lot of tutorials but I can't solve this problem.. Help?
