Device Configuration

The Device Configuration tab allows for easy configuration and setup of the HDC2022 device included on the HDC2022EVM. If immediate write mode is selected on the Section 3.5, then changes made in the selection boxes will be written to the HDC2022 device as soon as possible.

The Auto Measurement Mode, Temperature/Humidity Resolution, Measurement Configuration, activate Soft Reset, and Activate Heater widgets perform the same functions as on the Data Capture tab (refer to Section 3.2.) The other widgets are described below:

  • DRDY/INT_EN Pin Configuration: Selects the output for the HDC2022 interrupt pin
  • Interrupt Polarity: Selects the active/inactive state of the HDC2022 interrupt pin
  • Interrupt Mode: Sets the behavior of the HDC2022 interrupt pin.
  • Humidity/Temperature Offset: Sets the value of respective offset register within the HDC2022.
  • Humidity/Temperature Threshold: Sets the value of the threshold registers within the HDC2022.
  • HDC2022 Interrupt/DRDY Configuration Enable Bits: Selects the source of the HDC2022 Interrupt.
