编写一个中断处理程序，在主程序运行过程中，每隔10秒响铃一次，同时在屏幕右上角开窗口显示信息“The bell is ring!” 以及时、分、秒。(prepared an interrupt handling procedures, the main program process, beep every 10 seconds once, in the upper right open window screen display information, "The bell is ring!" And, minutes and seconds.)

基于LPC1768的串口控制台程序，使用的是宝马1768开发板。需要外接：串口、lcd1602；需要开发板模块：串口、A/D转换、五向键、I2C、rtc、定时器、内置512kE2PROM、GPIO。已完成测试，开机需输入密码：012345；可使用 , 或 . 键上下切换输入过的命令。可设置、显示时间日期及闹钟，可更改密码。个人开发，引用需注明CJ right.(This project is a serial console program based on LPC1768 ARM chip , its use of Baoma 1768 development board. Need external: serial port, LCD1602 module the need of develop board module: serial port, A/D conversion, joystick , I2C, RTC, timer, built-in 512k E2PROM, GPIO. Has completed the test, the boot need to enter the password at the first: 012345 can use the key of , or . to up and down switching input over the command. Can set, display the time date and alarm clock, can change the password.Personal development, please respect the copyright.)
