There is also Unity Learn's Create with Code that also has a teacher trainingthat goes with it. BitsBox is also great, my kids started out with it, and then moved onto Create With Code. Source: over 1 year ago

Maybe try Bitsbox? It teaches Javascript by making games. They can share the games with their friends, and it also leaves a lot of room for them to modify the games using what they learned. It teaches a lot of programming skills that are useful later. There is also Google's CS First, that's free and has a lot of different projects. It even has themes like games, sports, arts and stories so it might appeal to more... Source: almost 3 years ago

For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory. Source: 10 months ago

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino. Source: 10 months ago

PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats. Source: about 1 year ago

Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards. Source: about 1 year ago

If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO). Source: about 1 year ago
