Design of Digital Broadcast Radio System Based on STM32

Abstract

With the popularization of digital radio system, radio has also entered the digital age from the original analogue system. On the basis of the digital radio chip TEA5767 which used in the current widespread use of electronic products, this paper proposes and designs a digital broadcast receiving system based on STM32. The hardware circuit uses STM32F103VE as the main controller, with the configuration of digital radio chip TEA5767 and corresponding SD card storage module, LCD module, power module and so on; the software design adopts I2C bus to communicate and coordinate between the main controller and FM chip, achieving FM frequency and volume adjusting function. Meanwhile the μC/GUI is used to design the human-machine interactive interface. The digital broadcasting radio system has the advantages of small volume, multiple functions, low power consumption and easy to use.
