 |
|
Hi jbors!
You know I choose pycar iso as my carpc distro 
Now I wanna add support for my 20x4 LCD for displaying some info like song author and title, playing time...
But I don't know where to start!
I found pyLCD, a wrapper for lcdproc, and I'll use it to make work easier...
The problem is add code to yours...
Can you tell me where is the "place" to insert the code?
I know you used a graphical LCD, do you think I can modify the file ks0108.py placed in the "render" directory?
I'm new to python, sorry!
bye |

The pycar is working fine with graphical displays. This way render directory contains renderers for graphical info. If you want to display text info, it needs to be a standalone plugin/module which listens for audio/video player changes and renders them. I can do a module for you which will be able to call executables with text parameters.
Can lcdproc accept parameters like this or what's the interface it has ? |

I didn't do anything with lcdproc yet, but I know it is a deamon (LCDd) that listen to port 13666.
Pylcd ( http://www.schwarzvogel.de/software-pylcd.shtml ) is a wrapper that lets you control LCDd in python. It is simply a script that telnets the 13666 port and send the appropriate messages.
from pylcd-test.py:
| Code: |
import sys,pylcd,os
p=pylcd.client()
print "Connect message:", p.connect()
print "Info as know by the module:"
p.getinfo()
(sysname, nodename, release, version, machine)=os.uname()
s="s"
w1="w1"
w2="w2"
w3="w3"
p.screen_add(s)
p.widget_add(s,w1,"string")
p.widget_add(s,w2,"string")
p.widget_add(s,w3,"string")
p.widget_set(s,w1,"1 1 'Hello, LCD world!'")
print "printing 'Hello, LCD world!'"
p.widget_set(s,w2,"1 2 '%s: %s'"%(nodename, release))
print "printing '%s: %s'"%(nodename, release)
p.widget_set(s,w3,"1 3 'äöüß'")
print "printing 'äöüß'"
|
I only need to connect to LCDd, add a screen and some windget during initialization and simply send the appropriate string with widget_set...
Obviously I need to install LCDd and configure it properly!

The interface of lcdproc is little criptic.
I'll go ahead with the plugin skeleton which you may fill up with more details. |
