Target Communications Configuration

The CapTIvate touch library communications module has the capability of sending element data and sensor data to the host PC. Element data consists of all the low level data for a sensor's elements: current measurement count, long term average, and touch and proximity status. Sensor data consists of aggregate data for the sensor. This includes items such as slider position, wheel position, and global sensor status flags.

Both data types can be sent, as well as one or the other or none. On larger panels, it may be desirable to disable transmission of element data to increase the maximum report rate.

Implementation Notes
The protocol used to communicate between the target Captivate MCU and the PC running the CapTIvate Design Center is re-usable for communicating between the target and another embedded host processor or host MCU.

Affected Software Parameters
The Element_Data_Transmit_Enable parameter corresponds to the bElementDataTxEnable member of the tGlobalCaptivateSettings type in the CapTIvate Touch Library.
The Sensor_Data_Transmit_Enable parameter corresponds to the bSensorDataTxEnable member of the tGlobalCaptivateSettings type in the CapTIvate Touch Library.
