One will contain the sketch and one contains a few lines of code to hook in the Arduino core libraries and the main program from which the usual “setup()” and “loop()” components of a sketch are called. SymbolsĪdd two entries (these are applicable for Uno and Leonardo the first denotes “Arduno 1.0 libraries” and the second denotes a 16MHz clock): In addition, under “AVR/GNU Linker”, set the optimisation to garbage collect unused sections. Set the compiler to optimise for size and check the -ffunction-sections option. “C:\Program Files\Arduino\libraries\EEPROM” Optimisation

If you use any of the Arduno libraries, you must add additional entries to “Directories” for each one: e.g. The second of these would have “leonardo” instead of “standard” for the Leonardo board. C:\Program Files\Arduino\hardware\arduino\variants\standard.C:\Program Files\Arduino\hardware\arduino\cores\arduino.These are to be found wherever you installed the Arduino IDE. DirectoriesĪdd two entries to locate the source files for the Arduino core and be sure to un-check the “relative path” option. Under “AVR/GNU C++ Compiler” you should see several groups of properties. Open the project properties and select the “toolchain” set of properties. Start off creating a new Executable C++ project and choose the correct microcontroller type (ATmega328P for Uno and ATmega32U4 for Leonardo). Since there are differences between Uno and Leonardo, I created two versions of the following steps: one for each board. The approach taken can be broken down into two: configuring Atmel Studio and creating a C++ harness within which a verbatim Arduino sketch can be executed. The end point of the following, which is not as complicated as it looks, is that a new Arduino IDE compatible “sketch” can be begun by clicking the New Project icon in the tool bar and selecting one of two templates according to the target board.

Although I do have an AVR Dragon and could have used in-system programming (ICSP), I wanted to be be able to use the normal process of using the serial upload over USB and to leave the bootloader intact. There are two main parts to getting things to work: compiling the code and uploading to the arduino. It is partly written so I remember how it works… There were a few points where I wanted to do things a little differently this post is about the changes and some experiences along the way.

He approached the task with the kind of strategy I wanted and his account and example code saved me a lot of trial and error. The best I found, which is not at all “involved”, was by Elco Jacobs. There are several guides to achieving this kind of thing (Google “atmel studio arduino”) but most seemed to be rather involved and not well suited to having boards with different processors. A further complication is that I have both Uno and Leonardo boards, which have a different processor and so need separate code compilation. I wanted to be able to use Atmel Studio to create programs that would also be usable, ideally with no change, on Arduino boards with the Arduino IDE being used. I have also started writing some libraries and found the Arduino IDE to be a bit limited. not using the arduino or similar development boards). For my part, I began using it with an AVR Dragon board for programming micrcontrollers directly (i.e. The benefits of the Atmel Studio 6 IDE (if you can get to grips with it) are described in various places so I won’t repeat them here.
