单片机万历年电子钟Chip electronic bell million years(Chip electronic bell million years)

说明：  1602LCD显示程序，自己刚刚学会编的，分享一下，谢谢！！！(1602LCD display program, their series had just learned, to share, thank you! ! !)

c++程序实现的JPEG图片到RGB565 16位的LCD显示的数据转换程序.(c++ program to achieve the JPEG image to RGB565 16-bit LCD display of the data conversion process. )

降压斩波电路仿真，可以加深对dcdc变换的理解(Buck chopper circuit simulation, you can deepen the understanding of the DCDC transform)

说明：  利用定时/计数器T0从P1.0输出周期为1s的方波，让发光二极管以1HZ闪烁，设晶振频率为12MHz(The use of timer/counter T0 from P1.0 output cycle square wave 1s, so that the light-emitting diodes 1HZ blinking, set the crystal frequency is 12MHz)

仿真电话键盘拨号的电路图 C 以及HEX文件 是我的单片机考试作业(this is my master piece)

电子时钟的小程序，基于89c51单片机，可以实现定时、计时、修改时间等功能。(Electronic clock applet, based on 89c51 microcontroller, can achieve timing, timing, modification time and other functions.)
