摘　　要：为提高嵌入式设备的管理效率,设计了基于STM32的通信系统。系统硬件以STM32F407为开发板,通过RS232串口将TFTLCD触摸屏、SIM900A通信模块等硬件连接到开发板上。软件部分,在Keil5开发环境编写程序,实现了以MCU控制TFTLCD触摸屏和SIM900A模块工作。通过烧写程序,在TFTLCD屏幕观察到提示信息,实现了人机交互的功能。经测试,互联的系统之间的通话、短信发送达到了嵌入式设备通信的基本要求。In order to connect these devices together and manage them centrally and improve the management efficiency of embedded devices, designed was a communication system based on STM32.The hardware of the system takes STM32 F407 as the development board, TFTLCD touch screen,SIM900 A communication module and other hardware are connected to the development board through RS232 serial port. In the software part, the program is written in Keil5 development environment, and the TFTLCD touch screen and SIM900 A module are controlled by MCU. By writing the program, the prompt message is observed on the TFTLCD screen, with the man-machine interaction function realized. Through the test, the communication and SMS between the interconnected systems meet the basic requirements of embedded device communication.
