BUF08832EVM Software Overview
5.2.5 Reset Button
Pressing the Reset button in the BUF08832EVM software calls a General-Call Reset for the BUF08832.
The status of the DAC/V
COM
registers after the General-Call Reset depends on whether the OTP has been
programmed or not. If the OTP has been programmed, the channel registers will be loaded with the most
recent values programmed into the OTP memory. If the OTP memory has not been programmed, the
channel registers will default to 1000000000, or midsupply.
Pressing the Reset button does not generate a Read DAC call, so the corresponding channels are not
updated. The Read DAC button must be pressed in order to update the text boxes to the respective
current corresponding values.
5.2.6 Save to File Button
The register configurations of the BUF08832 DACs are displayed in both analog voltage and in
hexadecimal (see
Figure 13 ). The DAC codes (that is, gamma voltages) can be saved into a text file using
the Save to File button.
Pressing the Save to File button opens a file-save dialog box similar to that shown in Figure 19 . Pressing
the folder icon creates a new folder on your PC. It is a good idea to create a directory exclusively for
BUF08832 DAC code (that is, gamma voltage) files. Enter a unique file name in the Filename field to store
your BUF08832 register information. Press the OK button to save the file.
