rs422串口编程(RS422 serial programming)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)

一个非常完整的川口通讯源程序，我费了很大功夫才把他找到。(a very complete source Kawaguchi communications, I spent a lot of time and energy only to find him.)

调试串口的程序，本程序运行于PC机，是开发串口电路的好帮手。(Debug serial procedures, the program runs on PC, is to develop a good helper serial circuit.)

常用RS232串口通用库类，可直接使用,谢谢大家~(The common library of the RS232)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)

一个外国人写的rs485串口通信程序，有原理图和源代码，全面实现了485协议(a foreigner writing RS485 serial communication procedures, schematic and source code, the full realization of the 485 agreement)

介绍了一种点位运动控制器的设计，该控制器可以控制步进和伺服电机。该运动控制器以 STM32F103 为主控微处理器，实现了电机起停的加减速控制，扩展了 RS485 串行通信接口，设计了限位保护电 路，移植了嵌入式实时操作系统μC /OS-Ⅱ，通过μC /OS-Ⅱ来调度运动控制器的多个任务，设计了串口通信协议， 可以方便组成多轴控制系统.(Describes the design of a point of the motion controller, the controller can control a stepper and servo motors. The motion controller controlling microprocessor STM32F103, acceleration and deceleration control the motor starts and stops, extended RS485 serial communication interface, designed to limit protection circuits, transplantation of embedded real-time operating system μC/OS-Ⅱ μC/OS-Ⅱ scheduling multiple tasks of the motion controller, designed a serial communication protocol, can easily form a multi-axis control system.)
