title: Parade pt touch controller
|
|
|
|
description: The Parade 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.
