The controller will have four buttons, so 4 data pins are needed on the microcontroller plus a ground and 3.3V or 5V pin.
In total there are 6 pins needed.
If the game is going to be played by 2 person, there are 4 more data pins needed so 8 data pins for both controllers.
-For data transfer between STM32 and FPHA there are 4 pins needed at maximum (SPI for instance).
