The Data Capture tab reports the temperature from the TMP113 device included on the TMP113EVM. By default, once the EVM is connected and the GUI is loaded and running properly, the device starts in continuous conversion mode and the MCU starts polling the device. The conversion results are automatically reported and displayed in the Data tab graph.

On the right side of this tab, the user can view the latest temperature read value. There is also a chart controls box which allows the user to:

• Set the polling rate. Once a value is selected from the dropdown, the MCU automatically starts reading the TMP113 at the set polling rate.
• Write to the Conversion Rate bits using the Device Rate field. Once a value is selected from the dropdown, the MCU automatically writes to the TMP113, which then starts converting at the programmed rate.
• Start and stop polling the data read to export to CSV format for temperature monitoring. The user must start polling by clicking the Start button and the data (CSV) automatically exports once the stop button is clicked.

The Alert Config box allows the user to easily configure the alert functionality settings of the TMP113 such as polarity, mode, and limits. The limits can be written on the left box in decimal format, and the corresponding hexadecimal value is automatically displayed in the right box for reference. Once selected or updated, all of the settings are written automatically to the TMP113 by the MCU.
