I'm trying to connect buttons and a Joystick that are on one board with an ESP32 on another board.
I'm trying to keep it as simple as possible and just connect a pin to ground to tell me when a button is pressed or adjust the voltage being fed back to a pin to show the position of the joystick.
I feel that the USB-C connector is a good choice because it is small and well made with enough pins for my uses (I'm using 3 digital and 2 analog pins on the ESP32 as well as GND, 3.3v)
How would I go about connecting both sides of the USB-c to allow me to do that? Unfortunately I have only been able to get my own signals through the SBU1 pin and the D+/D- pins with a USB2.0 cable. When using a USB3 cable I am unable to use D+/D- nor Tx/Rx nor Tx1/Rx1
Any help would be much appreciated!
I'm only getting feedback on IO25 from S1.
