| In order to improve the practical teaching effect of Embedded System Course, an innovative experiment case, i.e., the 5G wireless speaker experimental system based on STM32F105 is designed. The software development method based on STM32CubeMX tool has been discussed. A new way of using the 5G wireless chips A5130 for the wireless transmission is proposed and ADAU1701 single chip audio DSP is synthesized to design the software and hardware. Finally, the 5G wireless speaker box equipped with 48kHz sampling rate is set up with CD-level tone quality, which can provide a scientific and reliable solution for the development of high quality wireless speakers. Based on this system, various experimental projects such as SPI, DMA, I2S, audio digital acquisition and signal processing can be carried out, which can fully enhance the students‘ability of hardware and software design. |
