基于stm32的RDM灯具控制系统
RDM Lamp Control System Based on stm32

在舞台美术中，光和色的组合是表现人物内心的重要因素；通过调整光比、设计用色可以创造舞台的空间感、时间感等客观因素和人物内心的主观表现。调整光比即控制舞台灯具设备的传统方法是采用单向控制的设备控制协议Digital Multiple X 512，而作为DMX协议增强的Remote Device Management协议采用双向通信，具有更为强大的功能。本文在STM32硬件系统基础上，搭载实时操作系统freertos，完成了基于RDM协议的舞台灯具控制系统，扩展了传统舞台灯具控制系统的功能。
In stage art, the combination of light and color is the important factors that express the inward world of the characters. By adjusting the light ratio and designing the color, we can create the ob-jective factors such as the sense of space and time of the stage and the subjective performance of the characters’ heart. The traditional way to adjust the light ratio, that is, to control the stage lighting equipment, is to use the device control protocol DMX512, which is one-way control, while the RDM protocol, which is enhanced by the DMX512 protocol, adopts two-way communication, which has more powerful functions. Based on STM32 hardware system and FreeRTOS, the stage lamp control system based on RDM protocol is completed, which extends the function of traditional stage lamp control system.
