MONITOR APPLICATIONS
INTRODUCTION
purpose this application note guide monitor application personnel using ST7FLCD code updating debugging. cost multi-purpose development comprises three connectors, finger switches, header, battery, EEPROM. used with application tools connect monitor D-Sub connector directly building ST7FLCD micro-controller. TheJig connect port, which also connects pattern generator monitor synchronously pins D-Sub connector. Then possible link pattern generator monitor synchronously.
different panels, resolutions, load different firmware EEPROM with this setting. enables debug, tune performance screen. stand alone mode Flash FUNCTION used download firmware embedded Flash without connecting schematic layout files also included this application note.
FEATURES
Flash function: code update without programmer. code storage: (64Kbyte Application programming. Line Debugging. Debug Port: access MCU/ADE3800 directly.

AN1991 Equipment Description: RS232 cable 1.5V battery Firmware ST7_ISP_Multi programming parPort driver (for first time user Connectors:
CN1: DB-25 Male: Connects port. CN2: DB-15 Female/Right Angle: Connects destination monitor. CN3: DB-15 Female/Vertical: Connects signal source, port pattern generator. JP1: Header 1x4: Connects scaler board.
Switches: SW1: Sub-switch1 used open/close connection between CN3. Sub-switch3 used turn on/off E2prom U1~U6 power supply from battery. SW2:
Sub-switch1~6 used open/close U1~U6 individually. (i.e. Sub-switch sub-switch2
U2,.) Sub-switch7 used open/close U1~U6.

OPERATION
Hardware connection: Connect port Connect Monitor connector Connect pattern generator connector Place three voltage battery battery case.
Driver installation: first time users with above Windows (Windows 2000, please follow this procedure. Windows users, please skip This implement takes port output, Windows 2000, users please execute "setup.exe parPort Diver" release right this port first (due this port being restricted OS). Flash Gun: Flash function enables users load firmware monitors EEPROM without connecting after loads firmware EEPROM. three voltage battery battery case. Turn channel Select EEPROM which intend load your firmware from channel turn (the capable expanding EEPROM six.). Turn channel data. Start store code following instructions below:
Store code box: Click "Open" icon open file, type password "ST" block Step ISP/DDCCI Password.

Load code MCU: Un-plug from Connect D-sub cable monitor. Select code want load ST7FLCD1 sub-switch1~6 SW2. Un-loaded codes need switched off. example: want load (A4) code MCU, then turn sub-switch3 sub-switch2, SW2. Turn off/on monitor once. Then, code will automatic programmed MCU. After code up-load completes, also stops blinking. might take seconds code loading complete.
