"无线对讲机综合实践论文：基于STM32和RDA1846S的设计与实现"

本论文是基于STM32F103RBT6单片机和RDA1846S对讲机RF射频芯片实现无线移动通信的综合实践设计。该系统具备发射和接收相同频率信号的功能，并能够手动切换发射和接收信号，同时实现收音功能。在频率调节方面，采用手动调节频率，并通过按键控制频率和音量的加减。除了基本功能外，还附加了录音放音模块，用于对说话内容进行录音。关键技术包括STM32F103RBT6、RDA1846S、对讲机和无线通信。这项设计对无线对讲机的研发具有重要意义。 关键词：STM32F103RBT6、RDA1846S、对讲机、无线通信 Abstract: This design is based on the STM32F103RBT6 MCU and RDA1846S radio frequency chip RF wireless mobile communication. The system can transmit and receive the same frequency signal, and can manually switch between transmitting and receiving signals, and also has a voice reception function. In terms of frequency adjustment, manual frequency adjustment is adopted, and the frequency and volume can be controlled by buttons. In addition to the basic functions, a recording and playback module is added to record the spoken content. Key technologies include STM32F103RBT6, RDA1846S, intercom, and wireless communication. This design is of great significance for the development of wireless intercoms.
