This function processes user touch events and updates the display.

The first registered touch is used to control the cursor. Its presence is indicated with a red frame around the display. When the cursor touch moves, its movement is visualized with a trace on the display.

The second registered touch is used to control mouse buttons, and is indicated with an inner frame of which the color depends on which side the touch is for: blue for left and green for right button click. The frame is shown until the touch is released. To detect which side click it is, the position relative to the cursor touch is used, i.e., a touch to the left of the first touch will cause a left mouse click.

Parameters
framenumberCurrent USB frame number
Note
This function should be called every millisecond, e.g., for each USB frame.
void ui_wakeup ( void  )

Wake the user interface up.

Exits the user interface of power down mode.
