摘　　要：在嵌入式系统串口数据传输中,不定长数据传输及高低速外设数据交互是两个需要直面的问题,解决这两个问题是实现数据可靠传输的重要保证。因此,基于STM32串口设计可靠的数据传输系统,探索不同串口方式在不定长数据传输中的效果差异,并采用双向链表暂存数据的方式来保证高低速外设数据传输的完整性,获得了良好的测试效果。In the serial port data transmission of embedded systems,the transmission of variable length data and the interaction of high and low speed peripheral data are two issues that need to be addressed directly.Solving these problems is an important guarantee for achieving reliable data transmission.The article designs a reliable data transmission system based on STM32 serial port,explores the differences in the effects of different serial port methods in variable length data transmission,and adopts a bidirectional linked list temporary storage method to ensure the integrity of high and low speed peripheral data transmission,achieving good testing results.
