Pololu AVR Library Copyright (c) 2008-2015 Pololu Corporation. For more information, see https://www.pololu.com/docs/0J20 https://www.pololu.com https://forum.pololu.com == Features == The Pololu AVR Library is a collection of support functions for programming AVR-based Pololu products or for using Pololu products with AVRs. It is designed for use with the free avr-gcc compiler, which is included with Atmel Studio 6 and WinAVR. Most of the library can also be used together with the Arduino environment. This library includes support for recent members of the Orangutan line of robot controllers: * Pololu Baby Orangutan B-48 * Pololu Baby Orangutan B-168 * Pololu Baby Orangutan B-328 * Pololu Orangutan LV-168 * Pololu Orangutan SV-168 * Pololu Orangutan SV-328 * Pololu Orangutan SVP-324 * Pololu Orangutan SVP-1284 * Pololu Orangutan X2 Additionally, this library supports: * Pololu QTR-1A and QTR-8A reflectance sensors for use with analog inputs * Pololu QTR-1RC and QTR-8RC reflectance sensors for use with digital inputs * Pololu Wheel Encoders * The Pololu 3pi Robot, a complete robot kit based on the Orangutan line == Installation instructions == Detailed installation instructions for Windows, Linux, and Mac OS X and tutorials for using Atmel Studio can be found in the Pololu AVR Programming Quick Start Guide: https://www.pololu.com/docs/0J51 The general instructions below apply to all development environments. == Prerequisites == The free avr-gcc compiler, avr-libc, and other associated tools must be installed before the Pololu AVR library. Once again, please see the Pololu AVR Programming Quick Start Guide for detailed instructions for Windows, Linux, and Mac OS X. To program your AVR, we recommend the Pololu USB AVR Programmer: https://www.pololu.com/catalog/product/1300 == Distributions of the Pololu AVR Library == The source code of the Pololu AVR Library is available as a git repository hosted on github: https://github.com/pololu/libpololu-avr The source repository is used to generate a binary distribution that has compiled binaries (.a files), headers (.h files), examples for every supported device, Atmel Studio 5 templates, and more. The binary distribution contains the source code of the libraries, but it does NOT include every file from the source repository. The binary distributions can be downloaded as zip files. You can tell what type of distribution you have by looking at what files are present in it. The source repository will have a src.mk file, while the binary distribution will not. For the convnience of Windows users, the binary distribution is packaged in an executable installer called the Pololu AVR Library Installer for Windows. This installer can be downloaded by itself and is also included in the Pololu AVR Development Bundle. The binary distribution zip files, the Pololu AVR Library Installer for Windows, and the Pololu AVR Development bundle are all available from the "Download Instructions" section of the Pololu AVR C/C++ Library User's Guide: https://www.pololu.com/docs/0J20 == Compiling the Pololu AVR Library == Open a command prompt within the library's top-level folder. If avr-gcc is correctly installed on your system, you will be able to type "make" to compile the entire library. Pay attention to any errors that occur during the build process. == Installation using "make install" == If you are installing the official version of the Pololu AVR Library on Windows, we recommend downloading the Pololu AVR Library Installer for Windows or the Pololu AVR Development Bundle which includes it. Otherwise, you should determine the location of your avr-gcc files. This will typically be one of: * C:\Program Files (x86)\Atmel\Atmel\Studio\7.0\toolchain\avr8\avr8-gnu-toolchain\avr * C:\Program Files (x86)\Atmel\Atmel Toolchain\AVR8 GCC\Native\3.4.1061\avr8-gnu-toolchain\avr * C:\Program Files (x86)\Atmel\Atmel Studio 6.0\extensions\Atmel\AVRGCC\3.4.0.65\AVRToolchain\avr * C:\Program Files (x86)\Atmel\AVR Studio 5.1\extensions\Atmel\AVRGCC\3.3.1.27\AVRToolchain\avr * C:\Program Files (x86)\Atmel\AVR Studio 5.0\AVR Toolchain\avr * C:\WinAVR-20100110\avr * /usr/lib/avr * /usr/avr * /usr/local/CrossPack-AVR/avr/ In this folder you will find an "include" folder that has AVR header files such as avr/io.h and a "lib" folder that has AVR libraries such as libc.a. In the library's top-level folder, type "make show_prefix". The Makefile will tell you where it thinks your avr-gcc files are. If the folder names displayed are correct, then you can run "make install" to install the library files. You will need to run this command with the correct permissions, so "sudo make install" will usually be required in Linux, and in Windows you will have to right-click on install.bat and select "Run as administrator". If "make show_prefix" does not show the correct folders, or the steps above don't work for you for any other reason, then you can install the library manually by following the instructions below. == Manual installation == If you have the source repository of the library instead of a binary distribution, you will need to build the library (.a) files by running "make" and also copy all the files in the "src" subfolder into the "pololu" subfolder. Next, copy libpololu_*.a into your avr-gcc "lib" subfolder. Finally, copy the entire "pololu" subfolder into your avr-gcc "include" subfolder. You are now ready to use the Pololu AVR library. == Manually installing special files for Atmel Studio 7 == If you are using Atmel Studio 7 in Windows, then you might want to install our Atmel Studio 7 templates so you can easily make new projects for Pololu boards. These files are normally installed by the Pololu AVR Library Installer for Windows, but you can do it manually if you need to. You will need to have a binary distribution instead of a copy of the source repository. To install the templates, simply double click on atmel_studio\extension.vsix and follow the instructions to install the extension into Atmel Studio 7. == Using the Pololu AVR Library == For more information about the library, please see the Pololu AVR C/C++ Library User's Guide: https://www.pololu.com/docs/0J20 == Arduino IDE == Parts of the Pololu AVR Library can be used in the Arduino IDE. For more information, see "Programming Orangutans and the 3pi Robot from the Arduino environment": https://www.pololu.com/docs/0J17
