Image Touch Screen (XPT2046) component

Low level routines for controlling or interacting with the XPT2046 touch screen controller IC found on a lot of common low cost resistive touch screen products.

Examples

Example using the XPT2046 touchscreen driver IC with a 4.3" TFT Display using the SSD1963 Graphical LCD Controller. FC6 Icon.png GLCD 4.3 Touch Example using the XPT2046 touchscreen driver IC with a 7" TFT Display using the SSD1963 Graphical LCD Controller. FC6 Icon.png GLCD 7 Touch

Downloadable macro reference

SampleSensor

Reads the touch controller and returns true if there is currently a touch in progress.

The touch coordinates can be read using the ReadCoord macro.

Return 0 = No Touch, 1 = Touch in progress

Parameters

This macro has no parameters


Return value

BYTE


ReadCoord

Reads a coordinate returned from the Sample Sensor macro.

Coordinate is scaled to the X/Y Pixel bounds specified.

Parameters

BYTE Coordinate
0 = X, 1 = Y, 2 = Pressure


Return value

UINT


Initialise

Activates the SPI peripheral and claims control over the I/O pins.

Parameters

This macro has no parameters


Return value

This call does not return a value


Simulation macro reference

GetConsoleHandle

Gets the handle to the console allowing data displaying on the panel etc.

Parameters

This macro has no parameters


Return value

HANDLE
