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.
