Front panel based on STFPC320
Introduction
This document explains the functioning of the front panel evaluation board based on the STFPC320 which consists of the front panel controller STFPC320 and microcontroller ST72F325 as I2C master. The basic idea is to develop a front panel for the DVD Recorder which is very close to the available solutions in the market. The objective of this evaluation board is to display the capabilities of ST's front panel controller/driver STFPC320 to fit the market segment of front panel of DVD players, DVD Recorders, VCR, Home Theater with Clock feature, HTiB (Home Theater in a Box), Personal Video Recorders (PVRs), Set-top boxes and other applications that require a compact, integrated solution, keeping the system cost as low as possible. The focus in the design of the system has been in 2 key areas - a Standby management feature for low power consumption and an embedded real time clock in the STFPC320 for auto wake-up and setting the recording start and end time. The system can be operated using:
Front panel keys Remote control
In the sections below the operation of the system is explained. When the board is connected to the power supply, the system is ready to perform any operation. At the time of manufacturing an additional board has been connected to allow in-circuit programming of the microcontroller. The two can be easily separated so that the front panel board can be used independently. To summarize, the key features of the demonstration board are:
16-segment, 11-digit customized VFD for DVD Recorder 14 front panel keys 4 LEDs (Red for standby, Yellow for schedule, Blue for IR and Green for Mute) 1 IR sensor for the remote control operation Buzzer on the board for Mute feature demonstration Real Time Clock to set the timer and alarm for wake-up On-board I2C EEPROM for time logging for automatic operations Power supply connector for four power supplies (3.3 V , 12 V, -30 V and GND) Standby management for low power operation Auto wake-up feature from system standby Embedded in-circuit programming capability

On the second key press," PAUSE" is displayed on the VFD along with the pause icon (II) on the left side of the VFD, as shown in Figure 9. Figure 9. PAUSE displayed on VFD
On subsequent key press operations, the VFD display toggles between "PLAY" and "PAUSE" depending upon the last message. Also, if other operations such as recording start either due to RECORD key press or record timer setting or we enter menu mode, the text message changes but the play icon ( ) or the pause icon (II) (depending on the system state) on the left side of the VFD remains on. This changes only if the system enters standby or keys such as OPEN/CLOSE, STOP, NEXT/FF and PREV/RR are pressed.
2.1.3
NEXT/FF
On the NEXT/FF key press, "FORWARD" is displayed on the VFD along with the forward icon ( ) on the left side of the VFD, as shown in Figure 10. This text message "FORWARD" is seen scrolling from left to right. Figure 10. FORWARD displayed on VFD
Subsequently, if other operations such as recording start either due to RECORD key press or record timer setting (see Figure 11) or we enter menu mode (see Figure 12), the text message changes but the forward icon ( ) on the left side of the VFD remains on. The icon changes only if the system enters standby or keys such as OPEN/CLOSE, PLAY/PAUSE, STOP and PREV/RR are pressed. Figure 11. FORWARD in background (RECORDING ongoing)
