3.2.4 Look Up Table Page

Figure 3-11 shows the Look Up Table page of the AFE10004EVM GUI. This page allows interaction with the four look-up tables in the AFE10004 device. Be aware that while the device is in LUT operation, the AFE10004 does not allow the controller access to the nonvolatile memory. The Disable LUT button stops LUT operation, and enables most features of the page. The GUI retrieves the table values for the currently selected DAC. The user is able to set the baseline, transfer function polarity, transfer function values, clamp values, and corresponding sensors for the LUT.

Figure 3-12 shows the LUT Transfer Function graph of the GUI. This transfer function is calculated based on the values of the look-up table. To exercise the transfer function (and the respective DAC output), enable the override temperature (OVRD TMP) feature of the device. Press the OVRD TMP button of the GUI to override the temperature sensor value with the user input. To manually sweep the temperature, use the TMP OVRD VALUE slider.
