电子时钟

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.)

本程序的功能是在TI的32位单片机LM3S9D96官方开发板上，基于IAR软件平台的，在触屏上显示一个动态的正弦波的C程序。用的是官方的开发板，液晶屏也是官方的。本程序是自己原创。程序非常规范，有详尽英语代码注释。 本程序是该单片机的一个高级液晶显示应用。(The function of the program is a dynamic sine wave C program in TI' s 32 the microcontroller LM3S9D96 official development board, based on the the IAR software platform, touch screen display. Official development board, the LCD screen is also an official. This program is original. The program is very standardized, detailed English code comments. This program is an advanced LCD microcontroller applications.)

这是一个气体传感器的元件封装库，型号为mq-135，使用dxp开发。(This is a gas sensor element package repository, model mq-135, using dxp development.)

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

stm32 mini板dht11温湿度测试程序(stm32 mini board dht11 temperature and humidity testing procedures)

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )

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.)

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.)

电子密码锁设计，实现四位密码开锁，可改密码(Electronic password lock design to achieve four bit password lock, password can be changed)
