Microchip公司的MCP4728是一个带有非易失性存储器(EEPROM)的四路、12位电压输出的数模转换器(DAC)，STC15系列单片机实现12位多路DAC数模转换程序。(Quad-channel, 12-bit, non-volatile, voltage ouput DAC with EEPROM, internal Vref and I2C interface. AEC-Q100 qualified.)

基于CP2200的TCP/IP驱动程序,是嵌入式网络连接的最简单方案(The CP2200-based TCP/IP drivers, embedded network connectivity is the most simple program)

crc校验程序，采样MEGA32单片机，可以设置为查表或者计算方式(crc check program, sampling MEGA32 microcontroller, can be set to look-up table or formula)

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.)

jQuery实现平滑的图片亮度渐变，鼠标移到图片上，可看到渐变效果，很平滑流畅的jQuery特效，代码也是超简洁的，可把此特效应用于图片展示、导航菜单中，制作一个鼠标高亮的菜单也是很不错的效果。(jQuery smooth picture brightness gradient, the mouse over the picture, you can see the gradient effect, very smooth smooth jQuery effects, the code is super simple, this effect can be applied to the picture display, navigation menu, make a mouse high highlighted menu is also very good results.)

次代码是针对STC8系列的单片机的延时函数，使用 此代码可以直接添加调用，程序自动获取内部系统时 钟后初始化延时函数。只要是ISP软件默认的时钟频 率都可以应用（特殊频率除外） 该代码为初版，还存在很多缺陷，请各位大佬勿喷，谢谢！ 注意： 次代码仅适用于STC公司最新的STC8系列单片机(Delay Function of Single Chip Microcomputer)

利用被动传感器坐标位置及测角误差 计算两站及多站无源测向交叉定位的精度矩阵 (The use of passive sensor coordinate position and angle measurement error calculation two stations and multi-station Passive Direction Finding Cross positioning accuracy matrix )

说明：  常见的单片机操作，IO，中断，定时器，低功耗模式等(io, interrupt, timer, low power mode and so on)
