跑马灯是一种电脑编程工具，利用涂鸦等效果显示文字。电脑中的跑马灯，跑马灯在编程中，通常指有时需要用一矩形条显示少量用户特别关心的信息，这条信息串首尾相连，向一个方向循环滚动。(The marquee is a computer programming tool that uses text such as graffiti to display text. In the computer, the marquee and the marquee are usually programmed to display a small amount of information that the user is particularly concerned with. This string of information is connected end to end and scrolls in one direction.)

Foreword The use of reprogrammable memory technology in vehicle electronic control units (ECUs) has increased in recent years, and is expected to continue in the future. Use of this technology has increased the flexibility of being able to use a single ECU hardware part to be used in many different vehicle configurations, with the only difference being the software and calibrations programmed into the unit. Reprogramming of those ECUs in the service environment also allows for ease of field modification of system operation and calibrations. Variations in reprogramming capability and the multiple tools necessary to reprogram vehicles are a burden on aftermarket repair facilities that service different makes of vehicles.

用于绘制LLC的增益曲线。把这段代码放到Matlab里，运行，就能够绘制出来LLC的增益曲线了。(This code is used to draw the gain curve of the LLC converter.)

使用cypress 蓝牙芯片，实现血压测量参考代码(This example project demonstrates the BLE Blood Pressure Sensor application workflow. The Blood Pressure Sensor application utilizes the BLE Blood Pressure profile to report blood pressure measurement records to the Client. Also the Blood Pressure Sensor application utilizes the Battery Service to notify the battery level and the Device Information Service to assert the Device Name, etc.)

很好的传感器学习资料，包括温度传感器、脉搏传感器。。。(sensor )

本论文设计了由AT89C52单片机为控制核心,用红外线为监测装置的防盗报警系统。该系统中红外对管作为红外线的发射和接收部分。发射部分采用红外发光二极管，而使用光敏三极管作为接收部分，接收红外发光二极管发出的红外线（不可见光）。单片机将通过内部的软件系统检测到接收管的导通或截止状态,并根据检测到的信号状态,进行判断并输出报警信号, 直至按复位按钮或电源开关。声光报警信号由9014三极管驱动构成声光报警电路,进行声光同时报警。电源部分采用变压器将220V交流市经变压器降压，桥式整流器整流，电解电容滤波，三端稳压管78L05稳压，最后得到整机要求的+5V稳定直流电源。实验表明，本系统成功运行。(This thesis is designed by AT89C52 microcontroller as the control center for monitoring device with infrared burglar alarm system. The system of infrared tube as infrared transmitting and receiving section. Emitting portion using infrared light emitting diode, a phototransistor as a receiving portion to receive the infrared ray emitted from the infrared light emitting diodes (not visible). The microcontroller will be detected by the internal software system to the turned on or off state of the receiver tube, and according to the detected signal state, to determine and output an alarm signal until a reset button or the power switch. Audible and visual alarm signal by 9014 transistor drive constitute sound and light alarm circuit, sound and light alarm at the same time. The power part of the transformer 220V AC City by the step-down transformer, bridge rectifier rectifier, electrolytic capacitor filter, three-terminal regulator 78L05 regulator, and finally get the machine requirements+5V)
