WINAVR AVR C Compiler

Introduction

WinAVR^TM (pronounced "whenever") is a suite of executable, open source software development tools for the Atmel AVR series of RISC microprocessors hosted on the Windows platform. It includes the GNU GCC compiler for C and C++.

Check out the WinAVR^TM project on Sourceforge at http://sourceforge.net/projects/winavr/ for developer information. Use the navigation menu on the left to find your way around this site.

WinAVR^TM contains all the tools for developing on the AVR. This includes avr-gcc (compiler), avrdude (programmer), avr-gdb (debugger), and more! WinAVR is used all over the world from hobbyists sitting in their damp basements, to schools, to commercial projects.

WinAVR^TM is comprised of many open source projects. If you feel adventurous, volunteers are always welcome to help with fixing bugs, adding features, porting, writing documentation and many other tasks on a variety of projects.

Try it Out

You can try WinAVR^TM out with Portable WinAVR^TM, a version that doesn't require an install. And when you get hooked on WinAVR^TM, you can put Portable WinAVR^TM on a USB key and take it everywhere with you! School, work, the library, the dentist, and more!

Portable WinAVR^TM is maintained at www.chip45.com/PortableWinAVR.

Build Your Own ARM Cross Compiler Toolchain

GNUARM is a set of open source GNU compiler for ARM microcontroller. The toolchain consists of the GNU binutils, GCC compiler set, Newlib and Insight, the graphical user interface to GNU debugger for Windows and Linux. This article will guide the building process of GNUARM toolchain only for Linux users. For Windows users, there have the installer executable EXE files already. www.scienceprog.comhas a tutorial on setting up this tool on Windows environment.

Get the sources
I will demonstrate the building process for GCC-4.1 only. For the others version, you can find the GNUARM distributions files from here. Here is the list of files that are required for the installation.

• binutils-2.17.tar.bz2 [13.1MB]
• gcc-4.1.1.tar.bz2 [37.3MB]
• newlib-1.14.0.tar.gz [7.61MB]
• insight-6.5.tar.bz2 [20.4MB]

I compiled the sources code with gcc-4.1.1 on Fedora Core 6 (kernel-2.6.18). Note that I built the toolchain as root. I also wanted the arm-target stuff separate from my Linux-native stuff, so I put the toolchain in /usr/local/gnuarm.

Building Instruction

[home]# tar xvf binutils-2.17.tar.bz2
[home]# tar xvf gcc-4.1.1.tar.bz2
[home]# tar xvf newlib-1.14.0.tar.gz
[home]# tar xvf insight-6.5.tar.bz2
[home]# cd binutils-2.17
[binutils-2.17]# ./configure --target=arm-elf \
--prefix=/usr/local/gnuarm --enable-interwork --enable-multilib
[binutils-2.17]# make all install
[binutils-2.17]# export PATH="$PATH:/usr/local/gnuarm/bin"
[binutils-2.17]# cd ../gcc-4.1.1
[gcc-4.1.1]# ./configure --target=arm-elf \
--prefix=/usr/local/gnuarm --enable-interwork \
--enable-multilib --enable-languages="c,c++" \
--with-newlib --with-headers=../newlib-1.14.0/newlib/libc/include
[gcc-4.1.1]# make all-gcc install-gcc
[gcc-4.1.1]# cd ../newlib-1.14.0
[newlib-1.14.0]# ./configure --target=arm-elf \
--prefix=/usr/local/gnuarm --enable-interwork --enable-multilib
[newlib-1.14.0]# make all install
[newlib-1.14.0]# cd ../gcc-4.1.1
[gcc-4.1.1]# make all install
[gcc-4.1.1]# cd ../insight-6.5
[insight-6.5]# ./configure --target=arm-elf \
--prefix=/usr/local/gnuarm --enable-interwork --enable-multilib
[insight-6.5]# make all install

Now, I hope everthing is done. You can test by running arm-elf-gcc command in the shell.

LED Moving Message Dispaly

This project is developed by me.The moving message consist of 19 Led matrix (5x7).The microcontroller used is AT89C51.Serial i2c eeprom is used to store the message.You can type max 40 chars in serial terminal to display message.Codes are written in c and compiler is Keil c51.Proteus simulation file is also included in

download.
