说明：  基于51单片机的电子钟设计。这个可以对于普通的51单片机，可以实现时间的计时，还可以设置闹钟，还有秒表功能，整点报时。(Electronic clock design based on 51 single chip microcomputer.This can be for the ordinary 51 microcontroller, can achieve the timing of time, but also can set the alarm clock, there are stopwatch function, the hour.)

enc28j60  51+uip0.9   tcp/ip协议嵌入式低位

智能追踪小车，并且可以用遥控手动控制转弯加前后左右(Intelligent tracking car, and can be controlled manually with the remote turn around Canada)

列出gbk2312中的每一个字符，并给出对应的编号(Listed gbk2312 in each character, and gives the corresponding number)

说明：  实现路由器功能，可以实现不同网段的主机之间通信，并且可以过滤ip地址和mac地址(Realize router function, realize communication between hosts in different network segments, and filter IP address and MAC address)

说明：  113、基于51单片机老人生理智能监控GSM短信 本设计由STC89C52单片机电路+火焰传感器电路+加速度传感器+心率传感器电路+SIM800A_GSM模块电路+电源电路组成。 该系统实时监测老人是否跌倒，是否周围有火以及心率情况。 1、如果火焰传感器检测到火焰，则GSM向特定手机发送：Fire！ 2、如果ADXL345检测到老人跌倒了，则GSM向特定手机发送：Fall！ 3、如果心率传感器检测到老人心率高于120，则GSM向特定手机发送：High Heart！ 4、注意本设计一次上电上述情况每个只能触发一次上报短信，不会连续发送，防止反复发送，请放心使用。 5、短信处理过程有GSM信号灯指示。 6、GSM模块是SIM800A，该模块和SIM900A电路程序完全兼容外观外形一模一样。(GSM SMS for elderly physiological intelligent monitoring based on 51 MCU This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit. The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time. 1. If the flame sensor detects a flame, the GSM sends: fire! 2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall! 3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart! 4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use. 5. SMS processing process is indicated by GSM signal light.)

产生一批随机数，使用TeeChart进行绘图。是TeeChart学习很好的程序。(Produce a random number, using TeeChart for drawing. TeeChart learning process is good.)

WiFi小车（简要说明：小车由msp430和stm32f103vet6两个单片机协调控制，msp430负责控制小车运动方向和开关电源的管理，stm32f103vet6负责视频数据的采集与传输，摄像头是ov7670，网卡采用enc28j60，移植的lwip协议，两款单片机均由ucos-ii进行任务管理。上位机控制平台由VC 6.0编写，可接收并显示视频数据，通过键盘W、A、S、D键来控制小车的行动） 对应博客文章https://blog.csdn.net/u012819339/article/details/50654679的项目源码，【小作品】STM32无线WIFI视频小车制作剖析。
