    Question:

    When does the status signal change for the proximity widget in CapSense tuner?

     

    Answer:

    In CapSense tuner for the proximity widget, there are two parameters that determine when the status signal changes.

     

    Proximity Threshold, which detects an approaching hand and Touch Threshold, which indicates a finger touch on the sensor.

     

    • When the Sensor signal crosses the Proximity Threshold value, the status signal in the tuner will change to 50%. (Sensor signal ≥ Proximity Threshold)
    • When the sensor signal crosses the Touch Threshold, the status signal in the tuner changes to 100% (sensor signal ≥ Touch Threshold)

     

     

    Note: The CapSense API for proximity—CapSense_IsProximitySensorActive (uint32 widgetId, uint32 proxId)—returns 32 bits of data. In this 32-bit data, only bit[0] and bit[1] indicate the status of the Proximity Threshold and Touch Threshold respectively.

     

    Bits [31..2] is reserved.
    Bit [1] indicates that a touch is detected.
    Bit [0] indicates that a proximity is detected.
