How to Stream Audio via I2S and Ethernet on W55MH32? Summary This project demonstrates how to use the W55MH32 to output audio via an I2S interface to an external DAC (e.g., CS4344) while integrating TCP-based Ethernet communication. The W55MH32 combines MCU functionality with a hardware TCP/IP stack, enabling real-time audio data reception over the network and direct playback through I2S without a software networking stack. What the Project Does The system uses the W55MH32 as both an audio playback controller and a network receiver. Audio data is received over Ethernet (TCP or MQTT)…
