Macro reference
Initialise
|
Initialise |
| Activates the SPI peripheral and claims control over the I/O pins. | |
 - VOID
|
Return |
ReadCoord
|
|
ReadCoord |
| Reads a coordinate returned from the Sample Sensor macro. Coordinate is scaled to the X/Y Pixel bounds specified. | |
 - BYTE
|
Coordinate |
| 0 = X, 1 = Y, 2 = Pressure | |
| - BYTE
|
Index |
| Touch Index Range: 0 - 1 | |
 - UINT
|
Return |
SampleSensor
|
|
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 = Single touch detected, 2 = Two touch points detected | |
| - BYTE

Stop Delay |
| On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications. | |
