Before you can start writing code that runs on ev3dev, you need to choose a programming language. Community members have built libraries that let you use features such as motors and sensors from your code. Choose the language you want from below and follow the link to the library’s homepage get started.
If the language you want isn’t listed, you still can use it, but you’ll have to do more of the heavy lifting yourself. You can look at the driver overview page for information on the interfaces you need to use to control devices. Once you get the hang of it, you can even write your own interface library and have it listed on the programming languages page!
Python is a high-level, general-purpose, interpreted scripting language. It is great for beginners, while also powerful for experienced coders. If you are new to programming and unsure which language to choose, Python is a great choice!
If you are just starting programming ev3dev, take a look at ev3python.com by @ndward. The site is intended to help users of the LEGO MINDSTORMS EV3 to begin using the ev3dev Python programming language to control their robot.
Warning! There is another Python library named
python-ev3 created by
@topikachu which is not the same as this one. When searching for documentation
online, make sure that you are reading about @rhempel’s
Java is a general-purpose computer programming language that is concurrent, class-based and object-oriented. In Java 8, the language added some functional features very interesting to learn.
The project has support for EV3 Sensors and Actuators. The project includes the support for LeJOS local navigation stack.
In this project, the Objects included in the different libraries follow the LeJOS Interfaces, not to be confused with another Java project based on ev3dev unified language binding for Java
Go is a compiled, statically-typed language created at Google. It aims to be simple and light while still providing modern language features. While it is a compiled language, it has its own built-in cross-compiler, which means that you don’t need to spend time setting up special tooling like you do with most other compiled languages.
C++ is a low-level, compiled language which is highly performant while still providing modern language features. It is best for applications which require the fastest execution or interaction with existing C++ libraries.
C is a low-level, compiled language which is useful for interacting with other C-based code. It is very lightweight and often the most portable across platforms.
Through GObject-introspection, this library can be used by languages including Vala and Genie, among many others. This is great for people who want to use higher-level syntax while still producing a performant application, or people who want a less error-prone API for C. The Brick Manager for ev3dev is written using this library.
Some of the libraries above also implement interfaces for other languages. If you’re looking for an alternative implementation for any reason, try out the options below.
Ev3devKit also has a Python wrapper. You can find demos of using ev3devKit from Python here.
Use them with caution, as some functionality will likely be broken. If you see a library below that you’d like to see in a better state, consider contributing to it to get it updated and ready to use.
