(Modern) C++ provides a lot of useful tools and functionalities that are beneficial for embedded software development like `constexpr`, `template` and anything that provides zero-cost abstraction. + +It's OK to include C code if this code comes from another library like FreeRTOS, NimBLE, LVGL or the NRF-SDK. + +## Coding style +The most important rule to follow is to try to keep the code as easy to read and maintain as possible. + + - **Identation** : 2 spaces, no tabulation + - **Opening brace** at the end of the line + - **Naming** : Choose self-describing variable name + - **class** : PascalCase + - **namespace** : PascalCase + - **variable** : camelCase, **no** prefix/suffix ('_', 'm_',...) for class members + - **Include guard** : `#pragma once` (no `#ifdef __MODULE__ / #define __MODULE__ / #endif`) + - **Includes** : + - files from the project : `#include "relative/path/to/the/file.h"` + - external files and std : `#include <file.h>`
