The Pololu USB AVR Programmer’s drivers (see Section 3.a). WinAVR: WinAVR is a free, open-source suite of development tools for the AVR family of microcontrollers, including the GNU C/C++ compiler for AVRs (avr-gcc). AVR Studio 4: AVR Studio 4 is a free integrated development environment (IDE) for programming AVRs offered by Atmel.

This tutorial covers the older AVR Studio 4, which is no longer supported by Atmel. For a tutorial on the newer Atmel Studio see. For a tutorial on AVR Studio 4 for Orangutan and 3pi robot users, see the guide. The following tutorial covers the steps needed to program AVRs in Windows using AVR Studio 4 and a Pololu USB AVR programmer. Specifically, we will write a simple program to blink an LED connected to pin PD1 of an AVR. If you want to program an AVR that does not have an LED connected to pin PD1, the code in this tutorial may need to be modified. You will need to download and install several pieces of software: • The Pololu USB AVR Programmer’s drivers (see ).

•: WinAVR is a free, open-source suite of development tools for the AVR family of microcontrollers, including the GNU C/C++ compiler for AVRs (avr-gcc). •: AVR Studio 4 is a free integrated development environment (IDE) for programming AVRs offered by Atmel. AVR Studio 4 works with the WinAVR avr-gcc compiler and contains built-in support for AVR ISP programming. If you have an Orangutan or 3pi and want to jump straight in to using your USB AVR programmer, you can skip steps 1–3 by downloading the AVR Studio project these steps would create. Determine the microcontroller on your device, download the corresponding file below, extract all the files to a directory, open the AVR Studio project file (BlinkLED.aps), and proceed to step 4. • mega48: (9k zip) • mega168: (9k zip) • mega328: (9k zip) • Open AVR Studio and click New Project.

Select AVR GCC for the project type. Enter the project name and initial file name. In the screenshot below, we named our project “BlinkLED” and elected to have a folder called “C: BlinkLED” created containing the blank file “BlinkLED.c”. Click Next >. DO NOT click “Finish” yet. If you do accidentally click “Finish”, you will not be able to perform step 2 and will instead have to set the device by going to the “Project” menu and selecting “Configuration Options”.

Creating a new AVR Studio 4 project, step 1 • Select AVR Simulator as the debug platform and then select the appropriate device for your target AVR. For an Orangutan or 3pi Robot, this will either be ATmega48, ATmega168, ATmega328P, ATmega324PA, ATmega644P, or ATmega1284P depending on which chip your Orangutan or 3pi Robot has. Click Finish. Creating a new AVR Studio 4 project, step 2 • Write your program in BlinkLED.c as seen in the screen shot below and click the Build button on the toolbar (or press F7). Building a project with AVR Studio Note: You will probably want to customize this program slightly if the clock frequency of your AVR is not 20 MHz. F_CPU should be defined as the clock frequency of your AVR in units of Hz.
