Complex state control experiment of vehicle standard atmosphere lamp based on Bluetooth communication

为了提高电子科学与技术相关专业学生的专业能力,加深学生对接口和通信协议的理解,拓宽他们关于嵌入式与蓝牙协同应用场景的了解,开发了一种蓝牙通信的车规级氛围灯复杂状态控制实验,在实际应用中为实现氛围灯复杂状态,需要对RGB的占空比实现精确的控制,并且在车规级的要求下,需要降低在复杂状态下所产生的干扰,实现难度非常大。文章采用车用芯片英迪芯开发板RuGby以及以nRF51822为核心的蓝牙模块,通过蓝牙模块以及氛围灯复杂状态的控制,帮助学生更好地了解蓝牙以及串口通信协议,以及嵌入式开发流程和PWM调光调色技术。

In order to improve the professional ability of students majoring in electronic science and technology,deepen their understanding of interface and communication protocol, and broaden their understanding of embedded and Bluetooth collaborative application scenarios, a complex state control experiment of vehicle standard atmosphere lamp based on Bluetooth communication is developed. In practical application, to realize the complex state of atmosphere lamp, it is necessary to accurately control the duty cycle of RGB. Under the requirements of vehicle specification level, it is very difficult to reduce the interference in complex states. This experiment uses vehicle chip indie core development board RuGBy and the Bluetooth module with nRF51822 as a core to help students better understand Bluetooth and serial communication protocol, embedded development process and PWM dimming technology through the control of Bluetooth module and complex state of atmosphere lamp.
