<title>EA65 front panel VFD </title>

The AOpen XC Cube-AV is a barebone designed for using as a media center.
|
|
It comes with a front panel display which is capable of displaying one line
|
|
of 9 characters.
|
|
</para>
|
|
<para>
|
|
The display is internally connected to the serial port
|
|
(<filename>/dev/ttyS1</filename>) with a fixed rate of 9600 baud.
|
|
</para>
|
|
<para>
|
|
The display uses 13 segments per character. That's why the driver provides
|
|
no custom characters like the ones for dot matrix displays do.
|
|
</para>
|
|
<para>
|
|
The front panel furthermore has 9 keys which are illuminated by blue LEDs.
|
|
The LEDs can be controlled with the backlight functions. The keys are not
|
|
supported by this driver. The red LED (RECORD) can be controlled with the
|
|
<code>output</code> command of <application>LCDd</application>.
