无刷电机是在嵌入式系统中广泛使用的动作机,文章给出了一种巧妙的无刷电机驱动方法,并且提供了驱动电机所需的汇编代码,用便捷廉价的方法,实现了无刷电机的驱动,而且有一个关键优势:不需要传感器!-brushless motor is in embedded system widely used in aircraft movements. The article gives a deceptively brushless motor drive, and provides the necessary drive motor assembly code, with convenient and cheap method to achieve a brushless motor drive, but is a key advantage : no need for sensors!

串行通信MCS-51单片机内部有一个全双工的串行通信口，即串行接收和发送缓冲器（SBUF），这两个在物理上独立的接收发送器，既可以接收数据也可以发送数据。但接收缓冲器只能读出不能写入，而发送缓冲器则只能写入不能读出，它们的地址为99H。这个通信口既可以用于网络通信，亦可实现串行异步通信，还可以构成同步移位寄存器使用。-MCS-51 microcontroller serial communication within the a full-duplex serial communication port, that is, the serial receive and send buffer (SBUF), these two physically separate receiver transmitter, both can receive data can be sent data. Only read by the receiving buffer can not write, but can only write to send the buffer is not allowed to deliver, their address is 99H. The communication port can be used for both network communications, can also achieve the serial asynchronous communication, but also constitute a synchronous shift register to use.

很全的信息熵资料，一个硕士论文和一个博士论文，对单通道多通道都有详细的见解-Very full of information entropy information, a master" s thesis and a doctoral thesis on the single-channel multi-channel has a detailed insight

运放选型 运算放大器的结构形式主要有三种：模块、混合电路和单片集成电路。对于设计工程师来说，不仅是要知道所用产品的型号，而且还应熟悉生产这些产品的工艺，从而能够从一类放大器中选出一种放大器做特定的应用。-Selection of operational amplifier OPAMP structure There are three main types: modules, hybrid circuits and monolithic integrated circuit. Design Engineer for example, not only to know the product you are using models, but also familiar with the production process of these products in order to be able to elect one Class A amplifier amplifier make specific applications.
