交通灯的设计开发，实现道路交通的智能控制，可以根据道路实际情况改变通行时间(The design and development of traffic lights can realize the intelligent control of road traffic, and change the passage time according to the actual situation of the road)

AVR单片机 定时器的应用 初始化 以及中断程序(AVR microcontroller timer application initialization and interrupt routine)

AD9858：频率从1M~120M输出可设置。通过测试。(AD9858: frequency from 1M ~ 120M output can be set. Pass the test.)

stm32，通过spi总线实现对于TI的2543AD进行读写操作，串口uart输出数据(stm32, achieved through the spi bus for read and write to TI s 2543AD, serial uart output data)

按键控制LED灯的汇编程序，可实现按键控制LED灯的亮灭，主要是用汇编语言写的可以学习汇编(Button control keys to control LED lights LED lights LED light button control keys to control LED lights)

使用方法： 程序设置了ENC28J60的IP为192.168.0.15，模块通电后与电脑的网口用网线连接起来， 设置电脑的本地IP为192.168.0.**（**自定），网关为192.168.0.15,其他默认，配置 成功后便可以arp或ping模块。 打开浏览器，在地址里输入http://192.168.0.15/123456可打开开发板简单网页，页 面上通过按键来控制开发板LED的亮灭。(Use: setup the ENC28J60 of IP to 192.168.0.15, the module is powered on the computer' s Ethernet port using a cable connection up to set the computer' s local IP 192.168.0.** (** Custom), the gateway 192.168.0.15, default configuration is successful, it will make arp or ping module. Open the browser, enter the address http://192.168.0.15/123456 to open the development board simple web pages, and page keys to control the development board LED light off.)

基于FRDM-KL25Z及简单运放（LM324）设计出了一套小巧、低成本的心电监测装置。它不但能够结合上位机实时显示心电图而且能够将采集的心电信号储存于SD卡，用于24h心电监护，以备观察不同时间段心血管疾病的症状。(FRDM-KL25Z and simple operational amplifier (LM324) based on the designed ECG monitoring device with a set of small, low cost. It can not only combine with the real-time display of the host computer and can store the collected ECG signals in SD card for 24h ECG monitoring for the observation of the symptoms of cardiovascular diseases at different time periods. )

该程序是CRC校验程序，可以查看文件的校验和，这对文件本身进行校验，也可用在其它程序中检难数据正确与否(CRC procedures can view the document and check that the document itself calibration, but also can be used in other programs Frederick hard data are correct or not)

通过WM_DEVICECHANGE来检测u盘的传播者源代码(through WM_DEVICECHANGE to detect u site promoters source code)
