The Toit language is now open source
Programming for Arduino in C/C++ has been the worst most unproductive endeavor I ever undertook as a software developer. I have no idea how people write whole browsers and operating systems in this language.Rewrote everything in CircuitPython after 1500 loc of cpp madness, and living happily thereafter. I had to switch to a more powerful board though, it would be great to have lower requirements. Adafruit's M0 adalogger board has been perfect for me in every way except it does not have enough flash for CircuitPython.Toit looks funky, but nice. They seem to already have a decent start at the ecosystem, with very basic libraries like drivers for HD44780 already made. Doesn't have everything that I need yet, but looks very promising.I'm working on a flight controller, not IoT, so I don't need their serviceability API, but that's an interesting way to monetize. If I needed that, I can definitely see it being cheaper to pay the fee than to develop stuff like a reliable OTA update system myself.
