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.

STM32是以Cortex-M3为核的处理器，该例程介绍STM32下如何对GPIO进行操作。GPIO在嵌入式领域可以说是必需要掌握的。-Cortex-M3 based STM32-core processor for the routine introduction STM32 how to operate on the GPIO. In the embedded area of GPIO can be said that the need for control.

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.
