BUF08630EVM Software Overview

5.2.5 Reset Button

Pressing the Reset button in the BUF08630EVM software performs two functions. The first function is to

call a General-Call Reset for the BUF08630. The status of the DAC/V

COM

registers after this General-Call

Reset has been called depends upon whether the OTP has been programmed or not. If the OTP has

been programmed, the channel registers will be loaded with the last values programmed into the OTP

memory. If the OTP memory has not been programmed, the channel registers will default to 1000000000,

or mid-supply. The second function performed after the Reset button is pressed is that a Read DAC call is

made to update the corresponding channel text boxes to the current value for each channel.

5.2.6 Save to File Button

The register configurations of the BUF08630 DACs are displayed in both analog voltage and in

hexadecimal (see Figure 15). 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 21. Pressing

the folder icon creates a new folder on your PC. It is a good idea to create a directory exclusively for

BUF08630 DAC code (that is, gamma voltage) files. Enter a unique file name in the File name field to

store your BUF08630 register information. Press the OK button to save the file.

Saved BUF08630 DAC codes (gamma voltages) exist in a text file that can be opened in a text editor, as

Figure 22 illustrates.
