I’ve created a small blynk app that works with an arduino UNO. I would like to perform the same thing with a NUCLEO STM32L476 hardware (that uses the STM32Duino framework which exposes the exact arduino API). This board is much more powerful for the half-price. But how can I manage this board from the phone app ? How can I use the digital PINs that are above #13 ? For instance, push button is D23, so which board should I use to set digital PIN #23 for an arduino-like board in the app?
By the way, how can I add a brand new board template in app ?
