2相四线八拍步进电机程序，可以正转反转，加减速(2 phase four line 8 stepper motor)

crc校验的一种计算方式，可以用于网络协议或串口、can协议的校验位计算，有封装好的函数(A calculation crc check can be used for network protocols or serial port, can protocol parity bit calculation, there is a good function package)

编写一段程序 统计从1000年到1999年之间闰年的个数 最后输出到屏幕上来(writing a program to sum up the numbers of leapyear between 1000 and 1999.Finally,showing the result on the screen.)

　Hittite公司以创新的设计使得其PLL产品性能优异，在相位噪声，杂散方面有着卓越表现，其芯片的高集成度使得外围电路简单，设计方便。所以随着电子技术的发展，对频率源的相位噪声性能要求越来越高，Hittite的低相位噪声PLL，在物理、天文、无线电通信、雷达、航空、航天以及精密计量、仪器、仪表等各种领域里都将大有用武之地。(The Hittite companies with innovative design makes the PLL excellent product performance, the phase noise, spurious aspects with excellence, its high integration chip makes the peripheral circuit is simple and easy design. So with the development of electronic technology, phase noise performance of frequency source is more and more high, the Hittite low phase noise PLL, in physics, astronomy, radio communication, radar, aviation, aerospace and precision measurement, instruments, meters and other fields will be great.)

很好的一个永磁同步电机的控制仿真模型，自己的参考。(Good control of a permanent magnet synchronous motor simulation model of their own reference.)
