Programming the ATtiny

Picture of Programming the ATtiny
This is a tutorial for programming the ATtiny chip. This tutorial will be more in depth than most. I will give you every step and tell you the things nobody told me when I first started programming ATtiny.



Things You'll Need

- Arduino Uno( Can be done with other boards but I will be using the UNO)

- ATtiny 85 or equivalent

- 10 uF Capacitor

- Jumper wire

- Breadboard

- LED

Step 1: Software

First off, we're gonna need the software. If you don't already have it, go to arduino.cc and download the latest version. Next were gonna need to install the ATtiny core files, which are included down below. Open up the arduino software and go to "file" and click on "preferences" take note of you sketchbook location. You'll need it later. CLOSE the IDE, if you don't it won't work until you do. Download the ATtiny core files I've included below. Go into the sketchbook and go to the hardware folder. Drag and drop the "tiny" file into that hardware folder. Now reopen the IDE and click on "tools" and then click on "boards". There should be a whole new set of boards availible including the ATtiny 85. For now, just leave the board as UNO.

Step 2: Arduino as ISP

Now we need to program the Arduino as an ISP( In-System Programmer). To do this go into the examples and look for ArduinoISP. Open this file and upload the sketch to the UNO as you would with any normal sketch. You have now turned the Arduino into an external programmer. One thing you should check is that you have the right programmer
selected. To do this go to tools and expand the programmer option towards the bottom. Make sure that Arduino as ISP is selected.

Is there anyway you can copy and paste your code into a notepad file and place it on here?

I did all that to my ATTiny85 and all i keep getting is OUPUT not declared in this scope

Hey, can you show me your reference on Attiny13 wit Arduino. I'm a newbie here

Hello, If you download the attached file and put it in the hardware folder. This will give you the Attiny13 as a selectable board from the boards pull-down menu in the Arduino IDE. The ATtiny13 has the same pinout as the Attiny85 and programming it is the same as any other ATtiny. Thanks to diy_bloke for the core files
