摘要
以基于CORTEX-M3内核的STM32作为控制核心,使用MT5320触控屏作为人机界面。以RS232为监控系统通讯的物理层,Modbus为通讯应用层,用STM32与触控屏进行通讯,实现对系统的监控;同时遵循高频开关整流模块的RS485通讯规约,实现对高频开关整流模块的输出电压和电流的调节及工作方式的设定。
In this paper a visual control system based on the CORTEX-M3 kernel for STM32 as the control core and the MT5320 touch screen as an interface is designed. The RS232 as the monitoring system communication physical layer and the Modbus for communication application layer are been used to realize the communication between the STM32 and the touch screen in order to monitor the system. At the same time it follows the high frequency switching rectifier module RS485 communication protocol, to achieve high frequency switching rectifier module output voltage and current regulation and working mode setting.
