real time RTOS

使用凌阳61单片机和1302时间芯片完成时钟功能并使用CH451LS芯片显示（程序中只在0号LED上显示秒）。是使用时，main.c是1302时间芯片的驱动，CH451LS0811.h是简单CH451LS芯片驱动。-The use of Sunplus 61-chip MCU and 1302 hours to complete and use the clock function CH451LS chip display (program only in its LED display 0 seconds). Is used, main.c is the 1302 driver chip time, CH451LS0811.h is simple chip CH451LS drive.

附件代码为自己根据Micrium官方代码进行更改移植，移植后的程序经过2天的不间断拷机，系统能够正常运行。

这个是个4个数码管显示时间的程序，用AT89S52实现，用四个按键控制，能实现时钟显示，闹钟定时，倒计时三项功能，电路图很简单。-This is a 4 digital tube display time-consuming procedures, use AT89S52 realize, with four buttons control, can realize the clock display, alarm clock, timer, countdown to the three functions, circuit is very simple.
