The Demonstration Application
2.4
USB HID CUSTOM DEVICE DEMO
The HID Custom Device demo enables generic USB data transfer to and from an
attached device. Although the HID class normally is used for interface products, such
as keyboards and mice, the HID interface can also be used for other data transfer
purposes. The precompiled application provided with the starter kit is meant to be used
with the PC application project, HID PnP Demo.exe , provided on the CD-ROM disc
that comes with the kit.
If the USB device has been plugged in and has successfully enumerated, the device
should be detected automatically by the demo PC application. Figure 2-5 shows how
the PC application appears in Windows XP.
After the device enumerates, the PC application reads the raw data from the touch
pads, the accelerometer (three axes acceleration and temperature) and the
potentiometer. The state of the touch pads (pressed or not) is displayed in the Visual
tab; all of the raw data is displayed in the Numeric tab.
