Software Mode Control
The CDB8422 may be used with the Microsoft ? Windows ? -based FlexGUI graphical user interface, allow-
ing software control of the CS8422 and FPGA registers. The latest control software may be downloaded
from www.cirrus.com/msasoftware . Step-by-step instructions for setting up the FlexGUI are provided as fol-
lows:
1. Download and install the FlexGUI software as instructed on the Website.
2. Connect the CDB to the host PC using a USB cable (make sure pin 1 and pin 2 of J20 are shunted).
3. Launch the Cirrus FlexGUI. Once the GUI is launched successfully, all registers are set to their default
reset state.
4. Refresh the GUI by clicking on the “Update All Devices” button. The default state of all registers are now
visible.
For standard set-up :
5. Set up the CS8422 in the “CS8422 Main Setup”, “CS8422 Receiver Controls and Status”, and “CS8422
Interrupt Controls and Status” tabs as desired.
6. Set up the FPGA and CS8406 in the “FPGA Controls” tab as desired.
7. Begin evaluating the CS8422.
For quick set-up, the CDB8422 may, alternatively, be configured by loading a predefined sample script file:
8. On the File menu, click "Restore Board Registers..."
9. Browse to Boards\CDB8422\Scripts\.
10. Choose any one of the provided scripts to begin evaluation.
To create personal scripts files:
11. On the File menu, click "Save Board Registers..."
12. Enter any name that sufficiently describes the created setup.
13. Choose the desired location and save the script.
14. To load this script, follow the instructions from step 8 above.
