设计一个十字路口交通信号灯，基本配置包括四个方向共组（红灯，黄灯，绿灯）‘还可以包括转弯灯（适用于单向三股以上车道），行人过马路信号灯（红灯，绿灯）。(Design a traffic signal lamp at the crossroads. The basic configuration includes four directions: the red light, the yellow light and the green light. It can also include turning lights (for one-way three shares or more lanes), pedestrians crossing the street signal lights (red lights, green lights).)

STM32F407基于FSMC并口读取AD7606的代码，实测可用，开发环境Keil(STM32F407 FSMC is used to read the AD7606 code, based on the measured available, the development environment Keil)

说明：  是一本关于C语言跟单片机接口的书,还可以.反正我看了很好.不知道是否适合你.(Is on a single-chip interface with C language book, also. Anyway, I saw very good. Do not know if for you.)

大多数自行车速度表工作通过使用霍尔效应传感器固定在自行车前叉。磁铁是附加到前轮上的辐条之一,它将与霍尔效应开关一次革命的车轮。速度计监测传感器计数轮革命。如果知道车轮的直径,距离可以很容易地计算如果你知道有多少革命的车轮。此外,如果时间完成革命,平均速度也可以计算出来。 对于这个问题,您将编写一个程序来确定总距离(英里)和平均速度(英里每小时)考虑到车轮直径,革命的数量和总时间的旅行。你可以假定前轮从未离开地面,并没有下滑或打滑。(Most bicycle speedometers work by using a Hall Effect sensor fastened to the front fork of the bicycle. A magnet is attached to one of the spokes on the front wheel so that it will line up with the Hall Effect switch once per revolution of the wheel. The speedometer monitors the sensor to count wheel revolutions. If the diameter of the wheel is known, the distance traveled can be easily be calculated if you know how many revolutions the wheel has made. In addition, if the time it takes to complete the revolutions is known, the average speed can also be calculated. For this problem, you will write a program to determine the total distance traveled (in miles) and the average speed (in Miles Per Hour) given the wheel diameter, the number of revolutions and the total time of the trip. You can assume that the front wheel never leaves the ground, and there is no slipping or skidding.)

使用485向外发送0-255的数字。 若开发板的485接收到256个字节数据，会把数据以16进制形式打印出来。(Use 485 to send out 0-255 digits. If 485 of the development board receives 256 byte data, the data will be printed in 16 form.)

connection的两种连通域方法，上传上去大家应该能看懂的，我从基础学的是能够看得懂，不懂得翻下书(The connection of the two methods of connected domain, uploaded you should be able to understand, I the foundation to learn is to be able to read, not understand through books)

the value of signatureAlgorithm field of the structure private AlgorithmIdentifier algId .

picc-std_9.60PL2，带破解，可以支持MCV08等PIC单片机，是现有的最新的与最全的PICC编译器(picc-std_9.60PL2, with a break, you can support MCV08 other PIC microcontrollers, is available with the latest and most complete PICC compiler)

机械臂控制，基于keil的程序，lcd屏控制(Manipulator control, keil-based program)

说明：  在abaqus中可用于自定义的粘弹性材料模型，材料模型采用的是三参量固体模型，可通过输入粘性参量和弹性参量定义材料的参数。(be used for some materials with the viscoelastic property)
