This section describes the ea65 driver which works with the front panel VFD display on the AOpen XC Cube-AV EA65 media barebone.
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.
The display is internally connected to the serial port
(/dev/ttyS1
) with a fixed rate of 9600 baud.
The display uses 13 segments per character. That's why the driver provides no custom characters like the ones for dot matrix displays do.
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
output
command of LCDd.
