The lis Driver
This section talks about using LCDproc with the VLSystem L.I.S MCE 2005 Vacuum Fluorescent Display (VFD) based on the FTDI USB-to-serial converter, the Microchip PIC-16F716 microcontroller, and the NEC UPD16314 display driver manufactured by VLSystem.

Features
This device uses a vacuum fluorescent display of 20 characters by 2 lines. Each each character is 5 pixels wide by 8 pixels high. The device is connected by USB. The FTDI chip translates the USB protocol to serial expected by the VFD driver chip, an NEC UPD16314. A programmable interrupt controller (PIC), the PIC16F716 by Microchip, provides the glue between the FTDI and the NEC chips.

Requirements
The driver depends on libftdi, version 0.8 or higher, from http://www.intra2net.com/en/developer/libftdi/.
libftdi itself depends on the libusb USB library.
When using a libusb based driver like lis, LCDd needs to be started as root.

Configuration in LCDd.conf

[lis]
Size = 	 Set the display size. The default 20x2 should be safe for most if not all users, since the device seems to be made only with this one size. But who knows …
VendorID = VENDORID 	 The USB Vendor ID of the device to use. If not given, it defaults to 0x0403 for a VLSystems L.I.S. MCE 2005 VFD based on a FT232BL USB-to-RS232 converter by FTDI, which was produced before March 2007.
It is usually not necessary to specify a VENDORID. Please do so only if you want to test a compatible device.
ProductID = PRODUCTID 	 The USB Product ID of the device to use. If not given, it defaults to 0x6001 for a VLSystems L.I.S. MCE 2005 VFD based on a FT232BL USB-to-RS232 converter by FTDI, which was produced before March 2007.
It is usually not necessary to specify a PRODUCTID. Please do so only if you want to test a compatible device.
Brightness = BRIGHTNESS 	 Set the initial brightness [default: 1000; legal: 0 - 1000. Values between 0 and 250 give 25% brightness, 251 to 500 give 50% brightness, 501 and 750, give 75% brightness, and values higher than 751 give 100% brightness.
