7 Open Source Projects You Should Know - C Edition ✔️

Overview

Hi everyone 👋🏼​
In this article, I'm going to look at seven OSS repository that you should know written in C, interesting projects that caught my attention and that I want to share.
Let's start 🤙🏼​


1. LVGL

LVGL is the most popular open source embedded graphics library to create beautiful UIs for any MCU, MPU and display type. It's supported by industry leading vendors and projects like Arm, STM32, NXP, Espressif, Nuvoton, Arduino, RT-Thread, Zephyr, NuttX, Adafruit and many more.
Amazing and beautiful project! 😎

DOOM Retro is the classic, refined DOOM source port for Windows PC. It represents how I like my DOOM to be today, in all its dark and gritty, unapologetically pixelated glory. I have strived to craft a unique and cohesive set of compelling features, while continuing to uphold my respect for that classic, nostalgic DOOM experience many of us, after all this time, still hold dear.
