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