Description

Introduction
The main control chip is composed of STC89C52 chip + TDA5807 core device. It is connected through the I2C bus between the master and slave devices. The software simulates the bus sequence to drive the TDA5807 chip to work. The program realizes the function of automatically searching for radio stations. The frequency receiving range is 87- 108MHZ, frequency band information is displayed in real time by LCD1602 LCD screen. The output audio signal is amplified by the power amplifier chip LM386 to drive the speaker to work.
The receiving sensitivity and sound quality are very good, and the anti-noise interference ability is strong, which effectively reduces the noise interference when listening to the radio station, and the sound becomes clearer under the action of the power amplifier chip.
Plus level indicators make listening to the radio a complete pleasure.
