    We are currently working on a POC for a project, here we need 4 pins to change high/low depending on the angle of the joypad in the dabble app, and 6 pins need to go high/ low depending on buttons pussed in the app (when pressed high, when relesased low). Very simple, will add example code below, where serial monitor already displays angle out from the app, and also if buttons are pressed, so all you need to do is add function to a given action. pin 21 = Up pin 19 = down pin 18 = left pin 05 = right pin 13 = start pin 15 = select pin 35 = X pin 13 = O pin 14 = Square pin 12 = Triangle Should be a very simple job for anyone with just a little experience in Arduino/ esp32

    The project is to make a design that uses inexpensive parts that are ready available/in-stock for a power converter/controller to drive three phase motor on 48 VDC. The controller will have a microcontroller to implement the control algorithm, and a power converter to perform fast switching three phases (upon switching signals) handling about 1 kW total. The switching scheme will follow classic asynchronous switching with three states: positive, zero and negative.
