- Jason Turner is well-renowned for his C++ evangelism (his C++ Best Practices repository and starter project may be of particular interest). He was on a podcast discussing the ins-and-outs of embedded programming; more resources are included inside of the show notes and on his website.
- This isn’t directly related to mbed programming, but Bare Metal CPP and the awesome-embedded-rust repository can greatly improve your embedded development skills (I apologize for the Rust advertisement).
- Memfault and Embedded Artistry have a plethora of useful resources.
