Hardware Description and User Guide

Introduction

The STFPC311 is an evaluation board designed for quick and easy evaluation of STFPC311 
Vacuum Fluorescent Display (VFD) Controller. The key features include:

17-segment, 11-digit VFD,

15 programmable Front Panel keys,

2 switches,

4 LEDs,

2 LEDs to display Standby and Mute status,

1 InfraRed (IR) Connector for remote control (RC),

Parallel Port for communication with PC,

External power supply to power up the controller and VFD Filament, and

STFPC311 Graphical User Interface (GUI) to demonstrate communication to the VFD 
controller as it has been interfaced with a micro controller.

The evaluation board package includes:
