该程序是CRC校验程序，可以查看文件的校验和，这对文件本身进行校验，也可用在其它程序中检难数据正确与否(CRC procedures can view the document and check that the document itself calibration, but also can be used in other programs Frederick hard data are correct or not)

能够驱动5v-12v直流电机电动小车的驱动不但要求电机驱动系统具有高转矩重量比、宽调速范围、 高可靠性，而且电机的转矩 -转速特性受电源功率的影响，这就要求驱动 具有尽可能宽的高效率区。(The drive of 5V-12V DC motor electric car requires not only the motor drive system with high torque-weight ratio, wide speed range and high reliability, but also the torque-speed characteristics of the motor affected by power supply power, which requires the drive to have as wide a high efficiency area as possible.)

这是avr单片机pwm输出程序，是电机控制不可缺少的，也是控制类里面比较重要的程序，好好学习一下吧(This is the avr microcontroller pwm output process, motor control is indispensable, and it is more important to control the class inside the program, learn about it)

通过单片机实现哈希函数SHA-1，C源程序完全可用，已经测试，外部加密芯片采用DS28E01-100(MCU hash function SHA-1, C source code fully available, and has been tested external encryption chip uses DS28E01-100)
