温度传感器DS18b20的最新驱动，供单片机学习开发参考使用(DS18b20)

说明：  强噪声背景下弱信号检测，采用平衡式取样积分电路。包含电路原理，基于IAR的msp430f149的DDS脉冲程序和峰值检波程序，检波方法：sqrt(Acos^2+Asin^2)(Strong noise weak signal detection, the use of balanced sampling integrator circuit. Contains circuit theory, based on the IAR msp430f149 of the DDS program pulse program and peak detector)

8位LED灯控制温度测量综合,labview(8 LED lamp control integrated temperature measurement)

实现智能数字显示仪表。要求8位数码管显示（4位显示测量值，4位显示设定值），4输入按钮（功能选择、数码管选择、数字增加、数字减少），可设定上下限报警（蜂鸣器报警）。K型热电偶（镍铬-镍硅），测温范围为0℃~1000℃。采用比例-积分控制、并用晶闸管脉宽调制驱动1000W电加热器（电源电压为AC220V）。(Intelligent digital display instrument. Asked 8-bit digital display (4 shows measured values, four display settings), 4 input buttons (feature selection, the digital control options, the number increased, the number is reduced), upper and lower limits can be set to alarm (buzzer alarm ). K-type thermocouple (Ni-Cr and Ni- Si), temperature range is 0 ℃ ~ 1000 ℃. Proportional- integral control, and using thyristor PWM drive 1000W electric heater (power supply voltage is AC220V).)

用于数模转换的c语言程序设计，基于ADc0809(For digital-analog conversion c language program design, based on the ADc0809)

oled屏幕上面显示时分秒，可自行控制暂停(Time and seconds are displayed on the OLED screen, and the pause can be controlled by itself.)

实现从打印机并口接收数据！并转换数据协议！通过CRC较验！发送出去！(Receive data from the printer parallel port! And convert the data protocol! CRC than experience! Send out!)

利用单片机作为芯片，利用点阵按钮通过继电器控制LED灯(Using single chip microcomputer as a chip, using bitmap button by relay control LED lights)

利用multisim编写的交通灯程序，里面包括PPT和老师的讲解，是北航电子信息工程教授的实验课答案，非常珍贵。(Use multisim write traffic lights program, which includes PPT and teachers to explain, is the electronic information engineering professor Northern experimental class answer, very precious.)

具備fat格式 讀取sd card內的圖片顯示在tft螢幕上 (lpc17xx系列)(HAVE FILE SYSTEM AND CAN READ PICTURE IN SD CARD THEN DISPLAY ON TFT(LPC17XX ))
