TODO: Link to how to set up Atmel Studio programmer. It can be set up to use the AVRDUDE programmer, so that you can upload code to the board. It's gonna feel closer to being in Visual Studio and it's easier to work in than the Arduino IDE. This is Atmel's own IDE created for development on their chips, like the Atmega328. A better choice in my opinion, is to simply use Atmel Studio if you start to get serious about embedded development. You can use it with an external code editor and simple use the Arduino IDE as the programmer if you wish. It's hard to edit code efficiently and it doesn't have as much customizability. For beginners and quick development, it's an ok IDE but once you start getting serious, it's very limiting. Arduino IDEĪrduino developed their own simple to use IDE for writing code and programming the boards. Arduino vs Atmel StudioĪnd IDE is an Integrated Developement Environment, meaning it's essentially a code editor with programming capabilities and usually some debug capabilities. This disturbs the timing and contributes to a less efficient LED cube.įor the reasons above and because the sole purpose of a LED cube is to quickly turn IO pins on/off, the Arduino framework was not used in order to produce a more efficient and accurate LED cube. For this to work, an interrupt routine has to run in the background, even if you do not utilize delay() or interrupts in your code. Arduino uses its own millis() function to keep track of time. The second part of the Arduino framework issues has to do with interrupts. While convenient, digitalWrite() is 15 to 30 times slower than manipulating the IO pins directly in C as intended by Atmel. These functions are part of the Arduino class, which is fundamentally a C++ class. When programming Arduino, to control the Input/Output (IO) pins, one uses digitalWrite(HIGH) and digitalWrite(LOW). However, it's entirely possible with little to no effort to upload the code to a standalone Atmega328, using Atmel Studio, if you don't wish to use an Arduino. The project was based on using the bootloader inside the Arduino board to upload the code. However, the code is fully compatible with the Arduino board and can be uploaded with the Arduino IDE. This gave a better and more efficient code. These reasons led the motivation to write the code in C rather than to use Arduino's C++ framework. In a LED cube, speed is very important, as well as memory for the light patterns. This can be limiting, because the Arduino framework is an abstraction layer that causes the Atmega328 to run slower than its potential. However, to program the chip on an Arduino board, one usually programs it with the Arduino IDE using the Arduino framework. The Arduino board is constructed with the microchip Atmega328. Difference between Arduino and Atmega328ĭifference between Arduino and Atmega328?.Supporting video tutorials found at YouTube(coming soon). The code was developed together with the Cube 3D programming tool. This project contains the code for a LED cube, using an Arduino board or the Atmega328 as a standalone with Atmel Studio.
