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 … Read more
