We’ve written a number of high quality libraries that work on an unprecedented number of boards, including Arduino, mbed, PicoSDK, STM32Cube, ESP-IDF and Raspberry PI. These libraries and frameworks are battle tested, having been used in literally thousands of live designs. Take a look at the “Products” section. See our production ready open-source libraries.
Not everyone wants to build commercial products on top of Arduino, and recently PicoSDK has been added to the list. If we get enough donations we’d consider supporting STM32Cube and ESP-IDF too.
We are audiophiles and as such like both listening to music and building audio equipment. TcMenu’s first use-case was an audio amplifier, and you’ll see many of the examples still show that. But rest assured, it has been used for many other purposes from Agriculture, Home automation, Model trains, Live audio control, Lighting control to name a few.
