QTouch Group A/B method Channel and Sensor numbering for UC3L
Figure 41 QTouch method Channel/Sensor numbering
The above Figure represents an example 4 Channel QTouch sensor arrangement along with the
channel numbers. The Channel numbering starts with the lowest SNS-SNSK QTouch method
pair number (SNS2-SNSK2 being the least in this case) and increases as the SNS-SNSK pair
number increases. Similarly the Sensor numbering starts with Sensor 0. The Channel number
signifies the order in which the QTouch Library stores the acquisition data in the memory.
Figure 42 QTouch method Channel/Sensor numbering when Group A and B are used
together
When both QTouch Group A and QTouch Group B method are used at the same time, the SNS-
SNSK pairs associated with the individual group alone must be taken into consideration when
determining the Channel number.
Note: The touch_qt_sensor_config API must follow the above Channel and Sensor numbering
when configuring the Sensors.
