用华北工控pc104嵌入式主板开发的ad数据采集系统应用于传感器采集处理( 您是不是要找： 用华北工控pc 104嵌入式主板开发的ad数据采集系统应用于传感器采集处理 NORCO pc104 with embedded motherboards developed ad data acquisition system applied to the sensor acquisition and processing)

DMM-32x-AT 板卡AD 测试程序(program for AD test of board DMM-32x-AT)

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.)

1664LED红外控制的定时器，可以通过遥控器远程控制时间的加减、暂停等功能。包括红外解码、红外码值处理(1664LED control program，which can be controled by both IR and keys。)

上位机，与51单片机进行通信，将从单片机发送过来获得的信息显示在显示界面上。(PC, with 51 single-chip communication, sent from the information obtained from the microcontroller is displayed on the display screen.)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)

红外遥控解码，基于51单片机的例程，简单实用，我在学习单片机的时候用到的(Infrared remote control decoding, based on 51 MCU routine, simple and practical, I used the time to learn microcontroller)

说明：  51单片机控制GSM模块发短信和打电话的C源码(GSM single-chip control module 51 send text messages and phone calls the C source)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)
