<title>Eyebox One LCD Module</title>
|
|
<para>
|
|
Eyebox One is a small rackmounted server marketed by Rightvision
|
|
(<ulink url="http://www.alcateleyebox.rightvision.com/"></ulink>).
|
|
This server has an LCD module, a keypad, two graphbars and some leds.
|
|
</para>
|
|
<para>
|
|
The LCD is a 20x4 alphanumeric module connected via standard DB-9 cabling and
|
|
connector.

I couldn't find any documentation about it.
|
|
All I know has been obtained with some reverse engineering.
|
|
It seems that it can run only at 19.200 baud.
|
|
Sending ASCII to the module will make it simply display that text at
|
|
its current cursor position.
|
|
The module has a built-in BIOS that recognizes commands (sent by transmitting a
|
|
single-byte "marker" signifying that a command is on the way, followed by
|
|
the single-byte command character itself along with any parameters, if needed)
|
|
allowing the programmer to clear the screen, position the cursor anywhere,
|
|
hide/show the cursor, on/off the backlight, and so on.
|
|
</para>

|
|
This module is fast. If updating less than the whole screen, the LCD can
|
|
update faster than can be seen by the human eye. This, of course,
|
|
more than meets LCDproc's needs.

<title>Eyebox One Driver and lcdproc client</title>
|
|
<para>
|
|
You can use the two Eyebox One graphbars, one as a free CPU meter, and one as a free RAM meter
|
|
with lcdproc client (see eyebox.c in lcdproc client sources).
|
|
|
|
In order to use it, you must execute ./configure with a special parameter:
|
|
<command>CPPFLAGS=-DLCDPROC_EYEBOXONE ./configure --enable-drivers=EyeboxOne</command>
|
|
|
|
This is only a BETA version modification, take it as a demo...

The following table translate from EyeboxOne Key to Logical Key.

EyeboxOne Enter Key is a \r character, so it's hardcoded in the driver.

You can find out which key of your display sends which
|
|
character by setting keypad_test_mode to yes and running
|
|
LCDd. LCDd will output all characters it receives.
|
|
Afterwards you can modify the settings above and set
|
|
keypad_set_mode to no again.
