Installing a Crystalfontz 634XE USB LCD for use with mythlcdserver

The goal of this page is to help configure a CrystalFontz 632 USB LCD Display

This device is a 4-line display, and compatible with LCDproc and Mythlcdserver.

This page assumes you have already compiled/installed LCDproc


If you have the default config file it will show

# The following drivers are supported:
#   bayrad, CFontz, CFontz633, CFontzPacket, curses, CwLnx, EyeboxOne,
#   g15, glcdlib, glk, hd44780, icp_a106, imon, IOWarrior, irman,
#   joy, lb216,lcdm001, lcterm, lirc,MD8800, ms6931, mtc_s16209x,
#   MtxOrb, NoritakeVFD, pyramid, sed1330, sed1520, serialVFD,
#   sli, stv5730, svga, t6963, text, tyan, ula200, xosd
Driver=curses

You will need to change the driver to CFontz.

Driver=CFontz

Now scroll down to the configuration for CFontz. You will want your configuration to match the following:

[CFontz]
Device=/dev/ttyUSB0
Size=20x4
Contrast=750
Brightness=1000
OffBrightness=0
Speed=19200
NewFirmware=yes
Reboot=no
USB=yes

Please edit the Device to the one that matches your configuration. Also edit Contrast and Brightness to your desired tastes. Information on making those changes can be found on the LCDProc website and documentation.
