[Embeded-SCM Develop] msTimer DL : 0: （原创）高精度计时器电路原理图。采用AT89S52加DP8573，实现两个功能：带掉电保持功能的日历时钟、由外部开关信号触发的高精度计时。-(Original) high-precision timer circuit schematic. Using AT89S52 plus DP8573, realize two functions: to maintain power-down function with calendar clock, by an external switch to trigger the high-precision timing signal.

[Embeded-SCM Develop] 电子钟 DL : 0: 基于51单片机的电子钟，可通过EC11旋转编码器修改时间，LCD1602显示时间。时钟精度可通过T0定时器的初值来调节，但是要实现高精度晶振的关系非常大，本程序只是粗略的进行电子钟的仿真，如果要实现高精度还是要用其他外接模块来配合。(Based on 51 microcontroller electronic clock, can be modified by EC11 rotary encoder time, LCD1602 display time. The clock accuracy can be adjusted by the initial value of T0 timer, but to achieve the high precision crystal oscillator is very large, this procedure is only rough conduct electronic clock simulation, if you want to achieve high precision or to use other external modules to cooperate.)
