步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机则转过一个步距角。-Stepper motor is the electrical impulse signals into angular displacement or linear displacement of the open-loop control components. In the non-overload case, the motor speed, and stop location depends only on pulse frequency and pulse number, regardless of the load change, that is, to add an electrical pulse signal, then turn one motor step angle.

sniffer_queued — — — — 基于 stm32This 是一个改进的嗅探器。不同于基本的 sniffer_ascii 和 sniffer_binary 项目，该项目进一步添加帧队列应用程序 （由受体组件提供） 中。此队列可以大大降低帧丢在嗅探器 node.attention 的概率： 如果嗅探器正忙着在输出前一帧通过缓慢的 UART 与计算机，在此期间的连续的帧可能会丢失。

ATMEL at91系列arm的官方驱动，串口等常用的都测试过了，很好，还有很多实例。已经应用在一个项目中了。-ATMEL at91 series arm of the official driver, serial port, such as commonly used are tested, and very good, there are many examples. Has been used in a project in the.
