LCDd configuration.

[Julez]

In trying to configure a Hitachi 47780 LCD purchased on ebay, I am able to get it to work nicely in windows on my system. But when trying to get it to work on Ubuntu is a little trickier. dmesg sees the device but it doesnt define the ttys that I can tell. LCDd needs a ttys and a port? I can't seem to find either.

My current LCDd.conf

# select the serial device to use [default: /dev/lcd]
Device=/dev/lcd

# set the initial contrast value [default: 560; legal: 0 - 1000]
Contrast=560

# set the serial port speed [default: 19200; legal: 9600, 19200, 38400]
Speed=19200



## Hitachi HD44780 driver ##
[hd44780]

# Select what type of connection. See documentation for types.
ConnectionType=lcd2usb

# Port where the LPT is. Usual value are: 0x278, 0x378 and 0x3BC
Port=0x378

# Device of the serial interface [default: /dev/lcd]
Device=/dev/ttyS0

lsusb shows

Bus 001 Device 003: ID 0403:c630 Future Technology Devices International, Ltd lcd2usb interface

dmesg shows

[    1.901296] usb 1-1.1: Product: LCD2USB
[    1.901297] usb 1-1.1: Manufacturer: Lcdmod Kit

[    2.076765] usb 1-1.4: New USB device strings: Mfr=1, Product=3, SerialNumber=2

Any help is appreciated to ensure I have the right LCDd.conf.

Hi,

naming the actual product you bought will help much. HD44780 is a generic controller. From the dmesg output it seems like a Lcdmod Kit display.

I suggest reading http://lcdproc.sourceforge.net/docs/current-user.html#hd44780-lcd2usb first.

For the lcd2usb device no Device or Port settings are required. Within the [server] section be sure to set Driver=hd44780 , then in the [hd44780] section ConnectionType=lcd2usb should be all you need.
