利用stm32芯片控制带霍尔传感器直流无刷电机驱动程序，能够实现直流无刷电机的启动停止换向及pid调速等功能，对于直流无刷电机的研究入门人员有很大的帮助

生成多项式的最高位必须是1。例如：CRC-CCITT标准的16位生成多项式：g（x）= x16+x12+x1+1；阶数r = 16 即：0x11021.最高位通常为1。-Generating polynomial must be the highest one. For example: CRC-CCITT standard 16-bit generation polynomial: g (x) = x16+ X12+ X1+ 1 order of r = 16 that is: 0x11021. Highest one usually.

使用89S52设计的电子钟，C51 编写，本例没有使用1302等时钟芯片，但本例完全具有时钟芯片的功能。比如基本的年月日，时分秒和星期功能，而且还有平闰年的天数自动补偿。由于采用的是全软件算法，时钟误差较大，采用高质量晶振可以减少误差。本例重在培养与训练初学者对C51的学习。-89S52 designed using an electronic clock, C51 preparation, in this case did not use 1302 clock chip, etc., but in this case complete with a clock chip functions. For example the basic date, time, and every second week of features, but also the number of days flat leap automatic compensation. As a result of the full software algorithms, the clock error of greater use of high-quality crystal can reduce the error. In this case focuses on training and training for beginners to learn on the C51.
