4.3 Using the FlexGUI Tabs
To restore one of several standard configurations predefined at the factory, use the Quick Setup drop-down box on the
“Board Config” tab, or use the Restore Board Registers... command to load any of the configurations starting with
“FACTORY--” in the file name. The file names are meant to be self-explanatory. For example, the script called
“FACTORY--analog_48k_12.288M_master_I2S_dual.fgs” configures the board as I
2 S master with a 48k sample rate and
12.288 MHz MCLK, using analog input type.
The factory scripts are written with special consideration to proper sequencing of device settings, for example, enabling a
device’s power down mode before changing its MCLK settings. Register settings saved using the method described in this
section DO NOT include sequencing and may result in unexpected behavior when restored in the FlexGUI.
4.3 Using the FlexGUI Tabs
The FlexGUI features a series of tabs which represent the high- and low-level controls, grouped together according to
function.
Fig. 4-3 shows the tabs in the FlexGUI interface.
