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	Return

	Channel

	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	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.
	Connections
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Configuration
	Analogue Mode
	X Pixel
	Y Pixel
	Flip X
	Flip Y
	Simulation
	Label
Label used to identify the component on the panel.
	Enable Interrupt
	Interrupt Macro
Macro called when the simulated display fires an interrupt.
	Simulate Comms
Allows the I2C communications to be simulated and piped through an API to real world hardware.
