步进电机用L298N单独控制 能调速 直流电机用L298N控制 能调速-Stepper motor control with the L298N alone can speed DC motor control to speed with the L298N

微机接口实验中典型的步进电机实验的课程设计，里面有实验原理，源程序，实验结果等。-Computer Interface Experiment typical stepper motor experimental curriculum design, there are experimental principle, source code, experimental results.

对于CRC校验的算法有直接算法和改进算法，在matlab仿真中直接用CRC-N Genraor 模块，它可以自身编码 ，哪位高手知道，CRC-N Genraor 模块运用的原理属于不属于上面所说的直接算法-For CRC checksum algorithm has a direct algorithm and improved algorithm, matlab simulation directly CRC-N Genraor module that can encode itself, w
