ADP-1XX5A User Manual 38
Drawing Mode
Drawing mode is a utility that lets the user draw on the screen using a finger or stylus.
This allows the user to test the touch screen and touch controller to see if it is
operational or is mapped correctly. The drawing mode can display either the matrix
address of points touched or just show lines drawn. One of the PenMount driver’s
strengths is a special mathematical algorithm that minimizes the occurrence of noise
and smooths the drawing of lines.
Beep Sound
All of PenMount’s drivers support the beep sound function; however, some PC
systems may only offer a fixed buzzer sound.
Beep Sound Adjustable
Software drivers for Windows systems let the user adjust the frequency and length of
the beep sound. The drivers let the user adjust the desired touch screen sound, as
well as turn the sound off.
Wake Up Function
The Wake Up function lets the user touch the screen and wake the system up from
‘suspend’ mode.
Point Calibration Data
The Plot Calibration Data function displays the touch screen linearity map, which is
available if the PenMount driver provides an Advance Calibration function when
touch screens age their touch linearity declines. This non-linearity is apparent when
the touched point on the touch screen is not the same as the point on the display.
The plot calibration data function shows the linearity status of the touch screen. This
is only a support function for the user. The exact linearity of a touch screen requires a
linearity test machine.
