title: Raydium WT030 touch controller
|
|
|
|
description: The Raydium Touch controller is connected to
|
|
the host processor via I2C. The controller generates
|
|
interrupts when the user touches the panel. The host
|
|
controller is expected to read the touch coordinates over
|
|
I2C and pass the coordinates to the rest of the system.
