说明：  内涵舵机控制的库历程等文件，分类细腻，有条理性，注释清晰(The documents, such as the history of servo control, are classified delicately, organized and annotated clearly.)

说明：  学习STM32的基础例程，对初学者很有帮助，主要是对DMA的基本操作(Learning the basic routine of STM32 is very helpful for beginners, mainly for the basic operation of DMA)

对PID的学习从入门到精通吃透，有助于初学者快速学习掌握(For PID learning from entry to master fully digested, to help beginners learn to master)

说明：  本系统采用下位机负责模拟数据的采集,从51单片机负责采集数据，并应答主机发送的命令，上位机即主机是负责处理接受过来的数字量的处理及显示，主机和从机之间用RS-485进行通信。这样用户可以在上位机上编写各种程序对文件中的数据进行有效查询和分析,有利于工业过程的长期正常运行和检查。该系统采用的是STC89C52单片机，此芯片功能比较强大，能够满足设计要求。(In this system, the lower computer is responsible for the acquisition of analog data, and the 51 single chip microcomputer is responsible for collecting data and answering the commands sent by the host computer. The host computer is responsible for processing and displaying the received digital quantity. The communication between the host computer and the slave computer uses RS-485. In this way, users can write various programs on the upper computer to effectively query and analyze the data in the file, which is conducive to the long-term normal operation and inspection of industrial processes. The system uses STC89C52 single chip microcomputer, which is powerful and can meet the design requirements.)
