利用28335的cpu-timer0的中断功能进行AD采集，并有AD校核程序(Use cpu-timer0 interrupt functions of 28335 AD acquisition, and checking procedures AD)

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)

基于单片机的数控开关电源设计，带仿真和详细程序。(NC-based single-chip switching power supply design, with simulation and detailed procedures.)

说明：  超声波测量电路设计利用超声波来实现距离、速度、流量、浓度等的检测 ,具有其他检测方法无法比拟的显 优点。(Using ultrasonic ultrasonic measuring circuit to achieve distance, speed, flow, concentration of detection, other detection methods have significant advantages unmatched.)

摘 要 电机转速是电机的一个极为重要的状态参数 文中介绍了几种基本的电机转速测量 方法 并对这些测量方法进行了比较 给出了基于加速度计进行电机转速测量的硬件电路设 计方法和测试系统的工作原理(Summary of the motor speed is an extremely important motor state parameters paper describes several basic motor speed measurement methods and these measurements were compared based on accelerometer gives the motor speed measurement hardware circuit design and test systems Works)

基于51单片机通信的其中一种，I2C总线通信。(I2C bus communication is one of 51 MCU communication.)

说明：  温度控制系统中采用NTC测温程序 使用二分法查表 测温精度为0.1(NTC temperature measurement program uses dichotomy to look up the table)

说明：  用MSP430F149做的一个示波器，用Timer A定时触发AD转换，串口发送给电脑，最高采样频率100ksps左右，LABVIEW的visa接受和显示波形并可以控制时间轴和波形放大轴。(oscilloscope with MSP430F149 , starting with Timer A to trigger AD converter, send to the computer with RS232, the maximum sampling frequency 100ksps around, LABVIEW visa accept the data and display waveform and control the timeline and waveform magnification axis.)

本程序是自己制作的一种4位数码管模块的内部程序，该模块用于大屏上动态数据的显示，通过RS485接口为其传送待显示数据，芯片是89C2051(This program is a four to produce their own digital control module' s internal procedures, the module for large-screen display of dynamic data, transmitted through the RS485 interface for data to be displayed, the chip is 89C2051)
