I am interested in adding a custom display with a touchscreen to the Dragonboard 410c similar to a phone. How can a touchscreen be connected to the board?
I’m using generic multitouch (hid-multitouch.c linux driver) capacitive touchscreen devices connected over USB. They… “just work”.
What touchscreen are you using ?
I think you can using either usb and hdmi, or the 60 pin DSI pins.
adrien3d; touch sensor is independent of the display output, so HDMI and DSI are invalid. Options here are USB and i2c.
