Supported Devices
USB Webcam
Webcams are a quick easy way to capture low quality images.
Since all requests we have received to support webscams were for hobby
projects, adding this feature is low priority. If there is an urgent need for
webcams in a commercial project, please contact us with details on your
project.
Smart Card Reader
Smart Cards are pocket-sized cards with integrated chips that can
hold various information about the user. These are very popular in
security systems, health and baking industry, and government
identification. For example, Common Access Cards (CAC), is a
United States Department of Defense smart card to identify
employees and military personnel.
A USB driver for Smart Media readers is currently under
development and is to be integrated into Embedded Master Module. This will provide raw
data access to the smart card and then user can do data decryption or authentication.
14.1.3 Other USB Devices...
There are many other USB devices that we haven't mentioned yet, some emulates one of
the standard classes and some uses virtual serial chipsets. You can either contact the
manufacture or look deeply in the specs and you will know if the device is using serial
chipset or one of the standard classes.
For example, Prologix offers a GPIB-USB controller. GPIB is a very
old interface that is used in instrumentation. The manual of GPIB-
USB controller clearly states that this device use FTDI chipset.
Another example, is CANUSB from Lawicel AB. This is a low-
cost CAN to USB cable. Looking at the picture on their website,
you can easily see that they use FTDI for USB connectivity.
Embedded Master has native CAN support but this can be an
additional channel.
