说明：  2015年电赛国测题，频率测量。基于stm32的频率测量。优点：精密度高，代码简单(In 2015, the National Test of Electricity Competition, Frequency Measurement. Frequency measurement based on stm32. Advantages: High precision, simple code)

说明：  stm32完整的工程模板,包括所有的固件库函数以及文件,适合新手学习(STM32 complete engineering template, including all firmware library functions and files, suitable for novice learning)

基于LabVIEW和PXI-7358多轴运动控制卡的地震模拟振动台控制系统设计(Control system design based on LabVIEW and PXI-7358 multi-axis motion control card shaking table)

AVR单片机应用系统开发典型实例 包含电路图，C语言源码及 ICCAVR的软硬仿文件(AVR single-chip applications include the development of a typical circuit example, C language source code and documentation ICCAVR like the soft and hard)

此程序例子是以C语言编写的一种实现烟花音乐效果的程序(The fire_work program example is written in C language to achieve a fireworks music program)

用stm32cubemx生成的usb键盘已经配置好带led反回功能(stm32cubemx usb key led ok ok)

DS1302+89c51的例程代码，实测可用(DS1302 STM32)

TCD1206 实现光源的采集，通过1549转换后传给单片机，单片机将数据通过串口传出( TCD1206 realize the collection source, through the 1549 conversion pass microcontroller, the microcontroller outgoing data through the serial port)

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msp430f149单片机，可以同时检查相位，脉宽，周期等信息！(Msp430f149 based microcontroller, you can also check phase, pulse width, period and other information!)
