What programming language is used for drones?

In simple words, we classify these programming languages into two major types which are known as:

  • Low-level Programming
  • High-Level Programming

Low-level Programming(Firmware):

Drones utilize both low-level and high-level programming languages depending on their specific hardware and intended application. In low-level programming, the focus is on the drone’s firmware, which coordinates the hardware components of the drone, such as the engine(s), propellers, ESC, and battery life, to enable fundamental functionalities and operations.

The drone firmware handles critical tasks, such as detecting the precise amount of power required by the motors by analyzing data from the drone’s Inertial Measurement Unit (IMU). This helps the drone to execute a safe and level flight, the most crucial aspect of any drone.

C and C++ are the primary programming languages used in low-level programming, although lower-level machine languages such as Assembly can also be helpful. These languages may not be the easiest to learn, but they provide a lot of fun and enable the programming of different aspects of the drone’s hardware and firmware.

In DIY/modular drone projects, the type of hardware kit used determines the programming language required to build the code. For instance, Arduino and Raspberry Pi are popular in drone kits, and the languages compatible with these modular hardware kits should be used. Most of these languages are derived from C/C++.

Arduino, for example, is a set of C/C++ controls that can be called through a port called Arduino sketch. Therefore, if you know enough about C++ and C, you can program drones with ease.

High-Level Programming:

High-level programming languages like Python are suitable for most general-purpose operations when programming drones. These languages have a shorter learning curve compared to low-level or middle-level languages. With high-level programming, you do not need to worry about register or cache-level memory operations because the API takes care of them.

When programming drones with high-level languages, you only need to focus on guiding the drone to the next waypoint, retrieving video feeds, and tracking objects. This kind of programming deals with the software aspect of the drone, treating it as an API that will respond to our control.

High-level programming interacts with the drone’s firmware to execute the intended response. For instance, controlling the drone’s elevation through the Flight Controller (FC) or sending information from GPS to move the drone to a GPS waypoint and adjusting speed is managed by high-level programming.

In high-level programming, we consider how the drone reads information from GPS and moves to the desired location, while the operations of the engines and ESC are managed in low-level programming.

High-level programming is user-friendly and more accessible, with Python being a popular choice for drone programming, and Java is another option. APIs are used in high-level programming instead of a natural language. For instance, the drone may provide a Java-based API to code the AR from Java with the support of an interface. Some APIs are derived from C/C++, so knowledge of these languages can be an essential asset.

Overall, high-level programming simplifies the process of programming drones, making it easier for beginners to start coding drones and focus on developing more advanced features.
