MSP430串口程序，串口接收与发送均用中断处理。当MSP430串口中断接收到PC机的指令后通过中断发送将数据发送出去。-MSP430 serial program, serial port receive and send all use interrupt handling. When the MSP430 serial receive interrupt instruction PC, adopted after the break to send the data sent.

基于AT89C51和DS18B20的最简温度测量系统 温度检测的传统方法是使用诸如热电偶、热电阻、半导体PN结之 类的模拟温度传感器。信号经取样、放大后通过模数转换，再交自单片机处理。被测温度信号从温敏元件到单片机，-Based on AT89C51 and Jane DS18B20 most temperature measurement system temperature detection is the use of traditional methods such as thermocouples, thermal resistors, semiconductor PN junction, such as analog temperature sensor. Signal sampling, amplified through the analog-digital conversion, and then deal with pay since the single-chip microcomputer. The measured temperature signal from the thermo-sensitive components to the microcontroller,

基于中断控制的声光报警器的设计.采用中断方式，设计一个声光报警器的硬件电路和控制程序。程序运行时，一旦8位开关信号量状态满足设定条件，就触发中断，使发光二级管按规律闪烁，同时扬声器播放一段音乐。 硬件设备包括一台微机、一个MFID微机实验箱、一块T型板，2输入四与门 74ls08、8位总线驱动器 74ls245、LM386A音频放大器、排阻、扬声器各一个，发光二极管8个，470uF电容2个、104电容4个，插线若干。 -Interrupt-based control of sound and light alarm design. Using interrupt mode, designing a sound and light alarm hardware circuits and control procedures. The program is running, once the 8-bit switch signal to set the amount of state to meet the conditions to trigger interrupts, so that light-emitting diode flashes according to the law, while speakers play a piece of music. Hardware includes a computer, a computer simulation, MFID box, a T plate, 2 input 4 and gate 74ls08, 8-bit bus driver 74ls245, LM386A audio amplifier, exclusion, speakers of a light-emitting diode 8, 470uF capacitor 2 a, 104 capacitors 4, plug-line number.
