基于UART从控总线申请的多机通信设计

Design of Slave Device Actively Applies for Bus Control Based on UART in Multiple Micro Controller Communication

在通信要求不太严格的情况下,为实现从机设备主动与主控设备通信,提出了一种基于UART的从控设备总线申请的通信方案并在以C8051F020单片机为核心的通信板卡上完成通信测试与物理扩展,该通信方案亦成功应用于一套智能图书柜管理系统中。

If the condition of the communication is not too strict,in order to achieve the slave device applies for communication with the host device,this paper presents a method of slave device actively applies for bus control based on UART in multiple micro controller communication and makes test on communication interface card using the C8051F020 MCU as the core and complete physical extension,the communication scheme is successfully applied to a set of intelligent figure bookcase management system.
