NetDCU3/DCUL7 - F&S Elektronik Systeme GmbH.

1 Overview
1.1 Display Interface
The NetDCU3 has a very flexible and powerful interface for
LCD and EL displays. Many different displays can be connected
directly to the NetDCU3 without the need of any further
hardware. Even the contrast voltage for STN displays is generated
on-board.
From the view of the software, the display driver is fully configurable
by the user. Some display types are already predefined,
so that a simple choice from a list is all that is required.
If the display is not already predefined, the user has the possibility
to adjust the driver to a new display by himself by setting
a few parameters. On Windows CE this is done by setting
some keys in the registry. On Embedded Linux, this is done by
setting an environment variable in the boot monitor program.
This is explained in separate chapters later in this document.
Regarding the hardware, the DCUL7 is very similar to the
NetDCU3. So everything that is said for the NetDCU3 in this
document is also true for the DCUL7. Here the display is configured
by setting the appropriate parameters in the CONFIG
structure. There is also a special chapter at the end that deals
with the DCUL7 configuration.
1.2 Display Adapters
F&S offers different display adapters to facilitate the connection
of as many different displays as possible to the NetDCU3.
For a lot of displays there are already tailor-made solutions
available and the appropriate adapter is mentioned in the section
for the specific display. For further information about the
adapters themselves see the separate document “Display
Adapters”.
