摘　　要：UART即通用异步收发传输器,是一种通用串行数据总线,它包括了RS232和RS485在内的接口和总线标准规范,被广泛应用在嵌入式设备间通信。本文以带有ARM处理器的SoC电路板和带有51系列单片机的MCU电路板通过UART进行通信为例,列举出三种合理的串口通信连接方案,加以分析和验证,最终可应用于不同嵌入式设备之间进行数据通信。UART(universal asynchronous transceiver)is a universal serial data bus,which includes RS232 and RS485 interfaces and bus standards.It is widely used in communication between embedded devices.Taking the communication between SoC circuit board with ARM processor and MCU circuit board with 51 series microcontroller through UART as an example,this study lists three reasonable serial communication schemes for analysis and verification,and finally can be applied to data communication between different embedded devices.
