摘要
针对车联网远程通信短时间内连续传输和处理大量数据的问题,采用STM32强大的外设功能为车联网终端通信性能提供了硬件保证,利用SPI和DMA技术相互结合发挥出STM32在终端数据处理和传输的最佳性能。经过测试分析,串口通信性能的提高可以使得车联网信息处理速度更快,使得车联网系统更加适应高速数据应用要求。
In order to solve the problem of continuous transmission and processing of large amounts of data in the car network for a short period of time,this study uses STM32 powerful peripherals to provide hardware assurance for the performance of car networking terminals.The SPI and DMA technologies are combined to exert the STM32 data processing and transmission for best performance.After testing and analysis,the improvement of serial communication performance can make the car networking information processing faster,making the car networking system more suitable for high-speed data trends.
