Arduino IDE and ATTiny45

Hi Gang

I'm keen to use the Arduino IDE to program an ATTiny45. I've watched the following video How-To: Shrinkify Your Arduino Projects but I'm having a problem. If I click Tools > Boards none of the ATTiny boards appear. I've followed the instructions and placed the appropriate folders and files in the correct locations. Any help would be greatly appreciated.

OS: Windows 8
Arduino IDE: Arduino 1.5.6-r2
Sketchbook Location: C:\Users\Jason\Documents\Arduino
File path for attiny: This PC > Documents > Arduino > hardware > attiny

Cheers

Did you install the third-party core?

If you use this core for the tiny:

You can choose between ARduino 1.xx and 1.5XX

Hi Gang

Sorry for the late reply. I've been under the weather.

@Erni: I've downloaded the latest version for 1.5 but the boards still do not appear. :frowning:

@spycatcher2k: Will an earlier version of Arduino work with Windows 8.1?

@johnwasser: I've tried installing both cores. :frowning:

Cheers

I'm using 1.0.5 on 8.1 successfully. And programming ATTiny85s.

Make sure you follow the instructions in the README. Often times the Boards.txt file is not completed properly.

Hi Gang

Thanks for the responses. I've followed through the instructions in the README file. I'm unsure what the following instruction means?

* In the "boards.txt" file, change the "upload.tool" entries to the appropriate value for your setup.

If I check the text file I find the following.

attiny45at8.upload.tool=arduino:arduinoisp

What do I need to do with the above statement?

As always appreciate the help.

Cheers

Just make sure that the other options are commented out with a hash mark like this

attiny84at1.upload.using=arduino:arduinoisp
# attiny84at1.upload.protocol=avrispv2
# attiny84at1.upload.using=pololu

That's all :slight_smile:
