Arduino IDE not recognizing core files for ATTiny85

Greetings Arduino board, I have run into a problem with the arduino IDE and I can find no mention of it on the forum.

I want to program some ATTiny85 chips that I have. I downloaded the core files from here https://code.google.com/p/arduino-tiny/. I install them, following the instruction in the included readme file. To be clear, I create the directory, /home/username/sketchbook/harware, and copy the directory, tiny, into it. I then rename the file Prospective Boards.txt to Boards.txt.

But when I open the arduino IDE and click tools --> board nothing has changed, I do not see any ATTiny boards listed. I have tried copying the tiny directory into the /usr/share/arduino/hardware/ directory, no dice. I have tried this with both versions available on the site I linked to.

I'm running arduino 1.0.5 on 64 bit Linux, Fedora 19 to be specific I installed from the IDE from the repo.

Thanks in advance

Missed by one letter…

/home/username/sketchbook/hardware

I then rename the file Prospective Boards.txt to Boards.txt.

The file system is case sensitive. The correct filename is[u][b][glow=yellow,2,300]b[/glow][/b][/u]oards.txt.

Last, you must close the Arduino IDE and restart for the code to pick-up the change! Sometimes, I have even fallen into this trap with an instance minimized and unnoticed on a busy desktop XD

Hi,

I'm having the same problem. I did the same steps but until now I can't use the attiny on the IDE!! Someone can help?

Ensure you are using 1.0.5 or 1.0.6

On Windows, the files must be copied into your Documents (My Documents) directory under \Arduino\hardware

Review the instructions on Google. All instances of Arduino must be closed. Restart Arduino and the selection will be available.

I did it with the master files (http://highlowtech.org/?p=1695), then I put these in /usr/share/arduino/hardware/ then did chmod -R 775 foldername

If you skip the chmod step you might not have the rights to read it, and it wont work!

Before doing anything funky, try chmod -R 775 foldername on the attiny folder in the sketchbook folder! If that doesnt work, do what I did, its surefire! I had issues too, but this works (on Ubuntu 14.04)!

Good Luck!!

I had exactly the same problem on Ubuntu 14.10
I solved it by removing “/avr” from the path.

The version from https://code.google.com/p/arduino-tiny/ will unpack to the path:
sketchbook/hardware/tiny/avr/

I moved it to “sketchbook/hardware/tiny/”

And everything worked.
