Dear lcdproc community,
|
|
|
|
I've added support for the LEDs on the Pyramid LC-Display to the
|
|
"pyramid" driver of lcdproc.
|
|
|
|
Since it seems that LEDs on an LCD are not directly supported by the
|
|
lcdproc API I've used the "output" command of the server to trigger the
|
|
LEDs, similar to what the IOWarrior driver does.
|
|
|
|
The Pyramid LC-Display exists in two different versions, with 3 and with
|
|
9 LEDs. 2 of these LEDs can not be controlled by software but are
|
|
usually hard wired to power and HDD. The other 1 or 7 LEDs can now be
|
|
controlled by sending an "output" command to the server. The one
|
|
argument to the output command is a bitmask that controls the LEDs.
|
|
|
|
bit 0: LED3
|
|
bit 1: LED4
|
|
bit 2: LED5
|
|
bit 3: LED6
|
|
bit 4: LED7
|
|
bit 5: LED8
|
|
bit 6: LED9
|
|
|
|
There's no way of finding out whether 3 or 9 LEDs are available, so it
|
|
is up to the software to do the right thing.
|
|
|
|
Example:
|
|
|
|
telnet localhost 13666
|
|
hello
|
|
output 67
|
|
|
|
will light up LEDs 3, 4 and 9.
|
|
|
|
output 0
|
|
|
|
will clear all LEDs.
|
|
|
|

|
|
|
|
Please apply attached patch to the lcdproc CVS.
|
|
|
|
Any comments are welcome.
|
|
|
|
