5. Getting Started - Software Installation (Firmware 1.B)
The Si471x Windows GUI (graphical user interface) Software is designed and intended for use only with the Si471x
evaluation board (EVB). This user guide is written to support Firmware Revision 1.B. The GUI software revision
number is available under help\about.
The GUI software development program uses host machine USB port to communicate with the Si471x EVB and is
tested for use with Windows XP and Windows 2000.
Note: If you have installed previous version of the GUI, please make sure that:
1. The old version is removed.
2. The Si47xx GUI folder located in “C:\Program Files\Silcon Laboratories Inc” is deleted.
Failure to remove the old version and its folder will cause Si47xx GUI to not function properly.
Below is a couple of screen shots illustrating how to remove the old Si471xx GUI and its folder.
