In the early stages of learning, the hardest part is finding learning materials, so today I recommend a repository that summarizes embedded open source projects.
This article carefully compiles some embedded-related resources, including but not limited to programming languages, microcontrollers, open source projects, Internet of Things, operating systems, Linux and more. These materials are continuously updated, aiming to create the most comprehensive embedded resource library on the internet.
