这是一个自制万年历的显示程序。能显示温度日期时间等。。。。。。(This is a homemade calendar display program. Can display the temperature of the date and time. . . . . .)

Visual C++数据库编程与实例 pdf超高清电子版与原书光盘，非常不容易搞来的，福利来啦！200多M，只能分割，敬请见谅！主卷是VisualCDatabaseProgramAndExamples.zip，还需要下载12个分卷，此为第5分卷(Visual C++ database programming with examples pdf electronic version of ultra-high-definition optical disc with the original book, is not easy to engage in, and benefit coming! More than 200 M, only split, please forgive me!)

步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
