Flat Panel/CRT Video Controller
The Little Board P6d system provides an integrated high-performance super-VGA video controller.
The standard video controller supports both CRT and flat panel displays, but only supports 3.3V
video panels.
Note
If you are using 5V panels, an Application Note can be downloaded,
which describes how to build a 3.3V-to-5V converter, or you can order
a voltage converter through a recommended third party. All this
information is provided on Ampro’s web site through the Virtual
Technician, by searching for “translator card” and viewing the
problem/solution text.
There are three connectors associated with the video display and complete hardware details about
each connector and its supported features are provided in the following sections. These connectors
are summarized in Table 2-30.
