In an instructable "Make an Attiny13 based IR proximity sensor for $2.42
(http://www.instructables.com/id/Make-an-Attiny13-based-IR-proximity-sensor-
for-2/)" by Dustin Andrews refers to having to install the Attiny13 core files.

Unfortunately the core files that are linked to do not contain the boards.txt file
that will let the Attiny 13 show up as choice under 'Tools-boards' in the IDE. If
you are a novice at installing core files this may seem daunting, but since I just
did it, I thought I'd just share that knowledge with you.

Do the following:
-Download the Attiny cores from: http://sourceforge.net/projects/ard-core13/
(http://sourceforge.net/projects/ard-core13/)
-Go to your sketches folder
-most likely there is a folder called 'hardware' if not, create that.
-open the hardware folder
-create a folder called 'attiny13'
-open that folder
-create a folder called cores
-open that folder
-create a new folder called 'core13'
-so now you have the structure /hardware/attiny13/cores/core13
-open that deepest folder and unzip the attiny core files to that folder
-go back to your /hardware/attiny13 folder
-create a text file called 'boards.txt'
open that file.

paste the following text in that file:

I got this 'boards.txt' file from here (http://elabz.com/arduino-shrunk-how-to-
use-attiny13-with-arduino-ide/), but had to adapt it a little as that file 'sneekishly'
suddenly changes the programmer in its last definition and also I had big
trouble getting more than 2 boards to show up, until I realised that 2 of the
board definitions carried the same name, so I had to change that as well.

So, just as a final check that you have done everything right:
Go to your hardware folderYou should see a folder there called attiny13
Open that folder
It should have 2 entries: a folder called 'cores' and a text file called 'boards.txt'
open the folder 'cores'
That should have one entry: a folder called 'core13'
open 'core13'. There you should find 13 files with 'h', 'c' and 'cpp' extensions.

To make it easy I made a zip file (http://dl.dropbox.com/u/52513692/attiny13.zip)

(https://docs.google.com/viewer?url=http://dl.dropbox.com/u/52513692

/attiny13.zip&embedded=false&chrome=false&dov=2) that should unpack with
the right directory structure. Unzip it in the 'hardware' folder

legit, thanks DIY_Bloke

Very good!

I was actually trying to install the 13 files and not working. Then i came across
your ible on it and you saved the day. Works perfectly.

Thanks

Nice work!

Did you also have to change the wiring.c like it says here
(http://tekstop.wordpress.com/2011/12/30/programming-attiny13-using-arduino-
isp-and-all-the-hacking-involved/)? I think I ended up needing to do that to get the
blink program to work at the right speed. It may not matter for the IR sensor.

diy_bloke (/member/diy_bloke/) (author) dustinandrews

No I did not do that. I did not try the
blink program, just quickly a few other
statements and that worked. I did not
really set out to validate the core, just
to instruct how to install the available
one.
A quick test showed me it was working

diy_bloke (/member/diy_bloke/) (author) diy_bloke

Let me add that I am not sure if the
link you gave above is the same core
and I used the 22 IDE, not the 1.0

diy_bloke (/member/diy_bloke/) (author) diy_bloke

I checked a bit further and it seems
that the article about changing the
wiring.c that you provide th elink for,

deals with a different core. That wiring.c has references to the 44 and 84,
whereas the one I describe above (that is coming from yr ibble :-) ) does
not have these. Also the header file 'iotn13.h' is not present in the core
(from 'Smeezekitty' you and I link to, suggesting the change in wiring.c
involves a different core.
