Topic: problem programming Attiny85 with UNO (Read 15 times) previous topic - next topic



I am following these instructions to program Attiny85:

First of all, I have realized that we cannot use arduino IDE 1.0. So I downloaded version 0022. There are no compiling errors in this version.

However, as I try to upload the simple blink example, moving the output to pin 2, I obtain these results:

Problem uploading to board:
Binary sketch size: 658 bytes (of a 8192 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I am doing exactly the same steps and connections as that webpage states... what is wrong?

Thanks in advance

Did you disable auto-reset using a 10 uF capacitor?

Yes, following exactly those instructions.

The error indicates that either the Arduino ISP sketch is not installed or that auto-reset is still firing.  I suggest working through the steps a second time.

http://hlt.media.mit.edu/?p=1695 Updated for UNO and 1.0 IDE. Works well, I have tested it. Of course, Coding_Badly's response still applies, but also make sure everything is wired and powered correctly. I spent an hour messing with the IDE files only to realize my reset resistor was connected to GND.  :smiley-red:
