3.2 Data Capture Tab

The Data Capture tab reports the temperature and humidity from the HDC2022 device included on the HDC2022EVM. To enable data capture, ensure that an auto-read delay from the drop down menu at the top of the page is selected.

Each selection option/button on this tab has a specific function as described below:

• Register Auto Read Delay: Changes the delay between register reads
• Measurement Configuration: Configures the HDC2022 to return temperature, humidity, or both.
• Humidity/Temperature Resolution: Change the number of measurement bits for humidity/temperature measurements.
• Auto Measurement Mode: Set the auto-measurement frequency of the HDC2022.
• Start Measurement/One-Shot Button: In shutdown mode, this button triggers a measurement. When an auto-measurement frequency is selected, this button begins measuring from the HDC2022.
• Celsius/Fahrenheit Select: Sets the GUI to display in Celsius or parenthetic. This does not change settings for the HDC2022 or EVM.
• Activate Soft Reset Button: Triggers a soft reset of the HDC2022.
• Activate Heater Button: Enables the heater on the HDC2022.
