This section talks about using LCDproc with the VLSystem L.I.S

MCE 2005 Vacuum Flourescent Display (VFD) based on the FTDI USB-to-serial
|
|
converter, the Microchip PIC-16F716 microcontroller, and

the NEC UPD16314 display driver manufactured by

<para>
|
|
This device uses a vacuum flourescent 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.
