mcu msp430F149中看门狗WDT的应用(mcu msp430F149 application of the WDT in watchdog)

关于瑞士SHT11程序，把采集的数据在液晶上显示(Switzerland SHT11 procedures on the data collected in the liquid crystal display)

12864上面的并行画线，可以画圆，三角形，正方形，直线，正弦波(12,864 above the parallel line drawing, you can draw a circle, triangle, square, line, sine wave)

一个很实用的Listctrl，可以加图标（连Header都可以加图标），可以单Item的编辑，有下拉框，可以改变底色和文字颜色(A very practical Listctrl, can be added icon (with Header icon can be added), can single-Item editor, has drop-down box, you can change the background color and text color)

超再生遥控-遥控步进电机正反转AB的程序(Superregeneration Remote- remote control stepper motor program AB)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)

本文以霍尔茨(HOLZER)法作为船舶轴系扭转振动的计算方法，着重研究了船舶轴系自由扭振的计算与分析，并对轴系扭振产生原因进行了分析，提出了一系列减振方法，以保证船舶动力装置的安全正常运行。(In this paper, Holtz (HOLZER) Act as the ship shafting torsional vibration calculation methods, focusing on the calculation and analysis of ship shafting torsional vibration of freedom, and the shaft torsional vibration causes analyzed, proposed a series of less vibration methods to ensure the safety of the ship s power plant running.)

时钟的应用源代码，可以让初次设计有关定时操作的人员借鉴。 (Clock application source code, allowing designers about the timing of the initial operation of reference.)

通过51单片机设计一个电子时钟，精确到秒，可以通过按键调节时间(By 51 microcontroller design an electronic clock, accurate to seconds, you can adjust the time by pressing a button)
