It&#39;s certainly not feature complete, but it does what it does and it actually works.</p> <p>The app was built with the express purpose of configuring the CF-635 in my audiopint <em>before</em> LCDProc is able to take over. It certainly makes the startup/boot sequence nicer, and it allows me to start LCDProc later in the boot sequence, maybe even asynchronously.</p> <p>The next step now is to build a small set of puredata (Pd) abstractions to talk directly to LCDproc via the netsend socket abstractions.</p>
