Next, proceed to Section 4 to install avr-libc for all of the AVR microcontrollers supported by GCC. The latest version of avr-gcc should now be on your path. configure -prefix=/usr/local -target=avr -enable-languages=c,c++ -disable-nls -disable-libssp If you want to try compiling FORTRAN, ObjectiveC, or GCJ for the AVR, you’re on your own! mkdir build Note that you need to compile GCC from a separate directory, and that we are specifying that only C and C++ be included. Run the following command: tar xjf ~/Desktop/gcc-4.3.3.tar.bz2Ĭd gcc-4.3.3 Configure, compile, and install GCC The full GCC, which includes the C++ compiler, not just gcc-core. Get gcc-4.3.3.tar.bz2 or a later version from the GCC FTP site or from a mirror closer to you if possible. Other distributions probably provide similar packages. sudo apt-get install libgmp3-dev libmpfr-dev Under Ubuntu, you can get these packages by running the following command. Recent versions of GCC (4.3.x) depend on GMP and MPFR, which can be Test.c:1: error: MCU "atmega328p" supported for assembler only Installing prerequisites If your version of gcc does not support the chip, you will see the following errors: unknown MCU 'atmega328p' specified You can test for support by creating an empty file test.c and running avr-gcc -mmcu=atmega328p test.c. Run the following command: avr-gcc -version Checking the currently installed version of avr-gcc The latest versions of GCC (4.2.3 and up) include support for the ATmega328P, as well as the ATmega48P, ATmega88P, and ATmega168P. The popular AVR programming software AVRDUDE includes support for the mega328 in version 5.6 and up. If you are using a system without 328P support, it is possible to install the latest version of the compiler and related tools from source by following the step-by-step instructions in Section 3. Ubuntu Linux versions 8.10 (intrepid) and up.Microsoft Windows, Linux, or macOS with MPLAB X 5.05 or later.Microsoft Windows, Linux, or macOS with the Arduino IDE.Microsoft Windows with Microchip Studio (or AVR Studio and WinAVR). The following systems have compiler support for the ATmega328 included: This chip is available on our A-Star 328PB Micro. Note: The newer AVR ATmega328PB improves on the ATmega328P by adding more pins and peripherals. This means that most projects based on the earlier processors can be easily upgraded to the 328, making it possible to fit more complex programs or deal with more much more data. The mega328 has twice as much program (Flash) memory, RAM, and EEPROM as the mega168, while keeping the same architecture and pinout as the earlier chips. You can also check out the code on the Simon Kit which you linked to since that is also written in the Arduino IDE.The Atmel AVR ATmega328P is part of the mega48/mega88/mega168 series of microcontrollers, which are used on the Orangutan Robot Controllers, Arduino boards, and in many other robot controllers and individual electronics projects. The first few lessons are on how to blink and control LEDs which seems to be what you are looking for. In order to learn how to code in Arduino, we recommend the SparkFun Inventor's Kit, you can also check out the manual online if you don't want to buy the kit. Because the whole thing is open source you can put a copy of the bootloader on this chip if you want, and you can use the Arduino IDE whether or not you use the bootloader. Then there is the Arduino IDE which is a software development environment designed to make programming easier. There is the bootloader which is a piece of code that allows the chip to be easily programmed over serial instead of with a special programmer. There are the Arduino boards (and their clones) like the Arduino Uno(and the SparkFun Redboard) which provide you with the chip as well as supporting circuitry. In fact the Simon kit you linked to actually uses this chip while running Arduino code.Īrduino is a hard concept to explain because there are so many parts. There is tons of example code for Arduino including example code for many of our boards. But assuming you are using your own custom board, or putting that all on a breadboard or proto board the Arduino IDE is probably the easiest place to start. The Arduino Uno is basically a development board for this chip providing you with things like a clock crystal, reset button, power regulation, and USB to serial adapter.
