Detailed description
No detailed description exists yet for this component
Examples
An example of how to sample read a capacitive touch display overlay using the component.
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 |
SetOrientation
|
|
SetOrientation |
| Allows the orientation to be overridden. | |
| - BYTE
|
Orientation |
| Range: 0 - 3 | |
| - VOID
|
Return |
Property reference
|
Properties |
|
LinkTo |
|
Bus Settings |
|
|
Channel |
| Channel selection | |
|
|
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 |
|
|
Apply Scaling |
|
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. | |
