Embedded Digital Tuning Radio Based on stm32

With the development of science and technology, people’s demand for material culture is also increasing. The development of radio with good sound quality, easy portability, certain technological content, and moderate price can meet market demand well. The embedded digital tuning radio based on stm32 uses a 32-bit embedded chip with fast processing speed, convenient development, and high-cost performance. At the same time, it is combined with TDA audio decoding chip to achieve digital decoding, cooperates with the LM386 power amplifier module to achieve high-quality audio output, and displays the search frequency through the OLED LCD screen, with high display brightness and clear display effect. The whole work is very in line with the aesthetics of modern people and enhances the technological impression of products such as radios in people’s minds.
