WAV audio playback terminal based on W55MH32

Project description

1. Introduction In real-world scenarios such as smart homes and industrial alarms, updating device voice content often involves the traditional "firmware modification → re-flashing" process—a cumbersome procedure. To address this pain point, we offer a WAV audio playback terminal solution based on the W55MH32 Ethernet microcontroller. The device can wirelessly transmit WAV audio files, eliminating the need for complex firmware flashing. Voice content updates are completed simply by sending the file to a host computer. This solution reduces development and maintenance costs while enhancing…
