Software Description
5 Software Description
A GUI software comes with the evaluation kit for the convenience of demonstration and evaluation. This
section introduces how to install the driver of the evaluation kit in a PC, how to start the GUI software, and
how to use the software.
5.1 Installation of the Driver
The evaluation kit is designed as a USB Human Interface Device (HID), similar to a mouse. For Microsoft
Windows 2000 or a later operating system (OS), the driver for the HID class is already built in. The driver
will be loaded automatically when the evaluation kit is connected to a USB port for the first time. The
operating system will indicate the following messages during the first-time connection to the USB port.
• The OS will automatically recognize the board and show the product name “USB Interface Board”
information, as shown in
Figure 9 .
• The OS will recognize the USB device as a “USB Human Interface Device” and show the message
as shown in
Figure 10 .
• The OS will install the internal driver to make it ready for users to use the evaluation kit. The
message is shown in
Figure 11 .
