单片机多机通信中从机串口中断服务程序设计

论述了在单片机多机通信中从机侧带有数据校验和重发机制的串口中断服务程序的设计。首先介绍了单片机中串口的工作方式,然后给出硬件连接环境,最后在论述从机侧串口中断服务程序设计的时候给出了单片机多机通信中使用的数据结构、通信流程、从机侧串口中断服务程序流程图以及状态迁移图。

The Design of Slave's Serial ISR in Single-chip Multi-communication

This paper describes the design of slave's serial ISR which can verify data and retransmit data in single-chip multi-communication.First,describes the work mode of serial port,and then shows the hardware connection diagram,and describes the design of serial ISR finally.
