Controlling CrystalFontz LCDs with Perl

Tue, 27 Nov 2007 05:58:00 GMT

Late last night I posted a first version of my Perl-based serial packet app for talking with the CrystalFontz 635:

It's not rocket science, but there just really aren't very many working implementations out there, let alone working implementations that allow one to save the LCD state as the boot state. It's certainly not feature complete, but it does what it does and it actually works.

The app was built with the express purpose of configuring the CF-635 in my audiopint before 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.

The next step now is to build a small set of puredata (Pd) abstractions to talk directly to LCDproc via the netsend socket abstractions.
