单片机串行口与PC机通讯资料全套设计及说明材料

利用STM32F103和ST7565R实现串行口的驱动程序。背光直接接3.3V.字符滚动功能未能实现。若有实现的请赐教。

实验内容：使用keill μVision4 开发环境创建工程，并将.HEX文件烧录到Proteus仿真软件中，从而实现两机串口通信，发送方通过串口使接收方产生流水灯的效果。

系统的主要功能是：从机安装在每个病房里面，病房中的每个床位分配有相应的呼叫按键，并对病房和病床分别编上号码，当病人按下呼叫按键后，系统会将病房呼叫信息以及对应的房间号码和床位号码远程传送到值班室，并以振铃和显示的方式通知值班医生有病人呼叫，值班医生可以根据显示的病房号码和床位号码前去处理，同时可以按下响应键通知病人呼叫成功，并对LCD显示的呼叫信息清除，以备其他呼叫显示。 12864,基于AT89S51利用MAX485半双工串行口通讯的病房呼叫系统(代码，仿真，论文)

单片机与单片机之间通讯，里面包含接受和发送程序，并有8个led灯光提示，根据发送内容，点亮相应的led。

书本代码，适合初学者

Docklight Scripting is an extended edition of Docklight RS232 Terminal / RS232 Monitor. It features an easy-to-use scripting language, plus a built-in editor to create and run automated test jobs. A Docklight script allows you to execute all basic Docklight operations (sending predefined data sequences, detecting specific sequences within the incoming data stream, ...) and embed them in your own test code. Docklight Scripting is also network-enabled. Instead of using a serial COM port, Docklight Scripting can establish TCP connections (TCP client mode), accept a TCP connection on a local port (TCP server mode), or act as a UDP peer. Docklight Scripting gives you both flexibility and simplicity. Within minutes you can build your own automated testing tools and create: · time-controlled test jobs (e.g. sending a diagnostics command every 5 minutes and reporting an error, if the device response is not ok) · repeated test cycles (e.g. endurance testing for a motion control / drive system) · automatic device configuration scripts (e.g. resetting a RS232 device to factory defaults before delivery) · fault analysis tools for service and maintenance tasks (e.g. running a set of diagnostics commands and performing automatic fault analysis) · protocol testers with automatic checksum calculations (e.g. CRC - Cyclic Redundancy Codes) · Docklight startup scripts (e.g. automatically starting a COM port logging task at PC startup) Docklight Scripting uses the VBScript engine, allowing you to write your tests in a simple, well-known scripting language. Docklight's basic functions and features are made available through a small and convenient set of Docklight script commands.
