In addition to displaying information from the accelerometer and touch pads, the
Numeric tab also has an interactive mTouch calibration button. Clicking on the button
automatically reruns the same touch pad calibration routine that is performed whenever
the starter kit is initialized. No additional input from the user is required.
Note that manual calibrations are not stored for future use, but are replaced with the
results of the automatic calibration the next time the starter kit is powered up.
This demo allows the device to appear as a serial (COM) port to the host computer.
If the starter kit is running this demo, and it is connected for the first time to a host
computer, the operating system may request a driver to install (i.e., an INF file). Select
the “Install from a list or specific location (Advanced)” option and point to the INF file
provided on the CD-ROM disc that comes with the board.
Once the device is successfully installed:
1. Launch a terminal emulator program, such as HyperTerminal.
2. Select the appropriate COM port. On most machines, this will be COM5 or
Once the starter kit is connected, it will send data from the acceleration sensor in raw
numeric format.
This demo uses the starter kit as a USB MicroSD card reader. The MSD (Mass Storage
Device) interface displays a new drive volume in “My Computer”, similar to a USB Flash
memory device (“thumb drive”). If a compatible card is inserted in the card slot, files can
be read, deleted and manipulated like any other drive on the computer, following
successful enumeration.
Common operating systems typically assign USB mass storage volumes (such as
Flash memory devices) to the next available drive letter. If the automatically assigned
drive letter has already been assigned to some other device (such as a mapped
network drive), a conflict can occur with some Windows operating systems. For more
information, refer to the Microsoft Knowledge Base article 297694 at the following link:
http://support.microsoft.com/kb/297694
To resolve this issue, do one of the following:
• Obtain the hot fix available from Microsoft
• Manually reassign the conflicting drive volume (such as a mapped network drive)
with a drive letter that is later in the alphabet (such as “Z”)

mTouch™ Calibration
The demo PC application is intended to be run under Windows and was
written in Microsoft
verify that the .NET Framework Version 2.0 (or later) redistributable pack-
age has been installed. To verify this, check the list of installed programs in
the Control Panel (from the Start button in Windows XP, Settings>Control
Panel>Add or Remove Programs).
If it is not installed, the .NET redistributable package is included on the CD
that comes with the starter kit. It is also available for download from the
Microsoft web site.
