[lcd4linux] Newbie

[Eric H. <Eri...@hm...>]

Greetings,

I just subscribed, read all the messages in the archive, and glanced through
most of the source code.

I'm thinking of adding some functionality to lcd4linux (at least my local
copy).  I want to make an interface through which the user can record and
playback .wav files using the command line interface to OSS\Linux (Open
Sound System for Linux).  I plan to do this mostly with calls to:
 - "exec" => to record, stop, and playback the sound files
 - "ls" => to determine current file size
 - "df" => to determine free disk space
and hopefully I can figure out how to get the audio levels off of the sound
card in real time also (so you can tell when the system is hooked up
correctly).

I figure the application I'm trying to write is actually pretty similar to
many others that must have been written using LCD4Linux in the past.  I'm
wondering if there is an example of an application which uses LCD4Linux for
something other than one of it's built-in purposes.  I'm also wondering if
there is any sort of tutorial, documented version of the source code (I
haven't done a CVS checkout yet), or documentation on how to extend the
functionality of LCD4Linux (other than by writing a new driver).

I'm sorry if these questions are annoying or ignorant, I tried to
familiarize myself with the codebase before pleading for help...  :)
