W55RP20 pi-pico C/C++ SDK를 이용한 네트웍 스피커 제작 및 테스트

Project description

This is a demo video showing the actual operation of a project to build a network speaker using WIZnet's W55RP20 (a chip combining the RP2040 and W5500 into one, the W55RP20-EVB-Pico board). Previously, we tested this using lwIP in an Arduino environment, but the low transmission rate made it difficult to reliably stream high-quality audio. Therefore, this time, we completely redeveloped the project using the official Raspberry Pi Pico C/C++ SDK. Key Implementation Details Hardware W55RP20 (Ethernet + RP2040 integrated chip) Audio output via I2S interface (using audio amplifiers such as…
