System Introduction
This sample project is designed to quick start evaluation of 8-COM segment LCD, enter &
exit low power consumption modes and setting of RTC based on MB9AA30N series MCU.
There are 3 different system modes, include normal mode, test mode and standby RTC
display mode (low power consumption). Additionally, LEDs are used to indicate the MCU
running status.
8.2
System Features

MCU LCD controller driver

RTC setting and calibration

Enter and exit low power consumption

Mechanical key and joystick driver

TSC key base on TSC_Lib

LVD used to control LCD display parameter

System Firmware Design
After power on, LCD displays “FUJITSU” lasts 3 s, runs normal mode and displays current
time. Then press the key to enter other display modes.
 Normal mode
Includes display current time and date, RTC setting and so on
 Test mode
Include key and LED indication, enter and exit standby RTC mode in test mode
 Standby RTC mode (Low power consumption mode)
Wake up and enter function
