SV_PWM

对RC500卡的读和写，假如刷卡正确的话模块上的LED灯就会亮，没有卡、卡不对、或是其他的不能识别的都不能通过(RC500 card to read and write, if correct module on the card will be light, LED lamp without card and card wrong, or other cannot identify cannot pass)

利用Arduino实现读取MPU6050的DMP四元数(Arduino MCU reads MPU6050 use a DMP quaternion)

ADS 0.18um library which have all kind of mosfet you need

本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)

单片机为at89s52控制步进电机正反调速实验,(The stepper motor positive and negative control experimental)

这是一个为数不多的用C语言编写的PIC12C508的RGB灯的小型控制器，交流同步信号检测，七彩跳变+七彩渐变，做LED的朋友可以参考，程序可以直接使用的；(This is a small controller RGB lights a few written by C PIC12C508, AC synchronous signal detection, colorful jump+ colorful gradient, do LED friends can reference, the program can be used directly )

基于51单片机的自行车测速系统protues仿真(Based the 51 microcontroller bike velocimetry system protues simulation)

可以用指令控制选择信道，设置发射功率，发送数据包（长度可选），接收数据包（接收时延可设），CC2430复位,内部温度传感器读取，定时器时长控制。底层函数基本做好，如果要加入新功能，可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)

编写的飞思卡尔的sd卡读写程序，可以完成对sd卡的扇区读写，效率高，执行速度快(Writing the freescale sd card reading and writing program, can complete the sd card to the sector, speaking, reading and writing, high efficiency, the execution speed)

PC与单片机进行通信。能够在VC6.0进行仿真。注意:visual2008不能仿真。(PC to communicate with the MCU. Can VC6.0 be simulated. Note: visual2008 not emulation.)
