基于51单片的可调时钟，可用键盘控制显示时分秒，利用定时器中断(Based on 51 single adjustable clock, the keyboard can control display minutes and seconds, use a timer interrupt)

该程序实现了用单片机来控制时钟芯片DS1302进行万年历的显示。 这个代码相对来说很复杂，注释比较多。 程序运行，首先设置时间。 按S19，进行某一位的设置，会看到某一位上面会闪烁。 按S20，数值加1. 按S21，数值减1. 设置完后，时间会进行运行。 另外,1602上也会有时间显示的。(The program implements the MCU to control the clock chip DS1302 conducted calendar display. This code is relatively complex, comment more, we can carefully analyzed. The program runs, the first set the time. By S19, conducted a one set, you will see a bit above flashes. By S20, the value plus 1. By S21, the value minus 1. After setting, the time will be run. Further, the time will be displayed in 1602.)

说明：  实现了tm4c1294的硬件i2c通信，很方便(The hardware I2C communication of tm4c1294 is realized)

说明：  使用c语言开发51版的ADC功能与LCD功能。(51 written using c language version of the clock, can realize the normal timing)

单片机按键识别，用于实现不同的键盘输入的识别与后续操作。(The single-chip button recognition is used to realize the recognition and subsequent operation of different keyboard inputs.)

在单片机应用中，基于keil使用简单的编程来设计简单实用的密码锁。(Microcontroller applications, based on keil use simple programming to design a simple and practical password lock.)

说明：  通过串口实时显示MOU6050数据，希望可以帮到大家(Real-time display of MOU6050 data through serial port, I hope it can help you.)

说明：  DHT11检测温湿度同时显示在LCD1602的代码(DHT11 detects the temperature and humidity while displaying the code on the LCD1602)

这是基于STC89C52编程开发的脉搏检测器，里面包含PCB原理图，程序代码和一篇参考论文。(This is based programming development STC89C52 pulse detector, which contains PCB schematics, program code and a reference papers.)
