Resistive Touch Screen Pin Connections
In an ideal world (linear, with no loss), the vertical position is equal to:
To compensate for some of the real world imperfections, VX
used to improve accuracy at the cost of two more conversions per axes. The new expression for
the vertical position then becomes:
Table 26-2.
The resistive touch screen film signals connects to the ADCIFB using the AD and ADP pins. The
X
(right) and Y
configurable through the Touch Screen Pin Offset (TSPO) field in the Mode Register (MR) and
allows the user to configure which AD pins to use for resistive touch screen applications. Writing
a zero to the TSPO field instructs the ADCIFB to use AD0 through AD3, where AD0 is con-
nected to X
ADCIFB to use AD1 through AD4 for resistive touch screen sequencing, where AD1 is con-
nected to X
When the Analog Pin Output Enable (APOE) bit in the Mode Register (MR) is zero, the AD pins
are used to measure input voltage and drive the GND sequences, while the ADP pins are used
to drive the VDD sequences. This arrangement allows the user to reduce the voltage seen at the
AD input pins by inserting external resistors between ADP0 and X
which are again directly connected to the AD pins. It is important that the voltages observed at
the AD pins are not higher than the maximum allowed ADC input voltage. See
page 610
ADP pins.
By adding a resistor between ADP0 and X
at the AD pins can be controlled by the following voltage divider expressions:
The Rfilmx parameter is the film resistance observed when measuring between X
Rresistorx parameter is the resistor size inserted between ADP0 and X
and Rresistory is the same but for ADP1, Y
