ESP32-音频I2S

️该库仅适用于 ESP32-S3 等多核 ESP32 芯片。它不适用于 ESP32-S2 或 ESP32-C3 ️

通过 I2S 与外部硬件播放 SD 卡中的 mp3、m4a 和 wav 文件。包括 HELIX-mp3 和 -aac 解码器。还有一个用于 Fullband 的 OPUS 解码器、n VORBIS 解码器和一个 FLAC 解码器。与 MAX98357A (带 DAC 的 3 瓦放大器) 配合使用，将三条线 (DOUT、BLCK、LRC) 连接到 I2S。对于立体声，需要两个 MAX98357A。 AudioI2S 可与 UDA1334A（Adafruit I2S 立体声解码器分线板）、PCM5102A 和 CS4344 配合使用。其他硬件可能可以工作，但未经测试。还可以播放 icy-streams 和 GoogleTTS。可以用Arduino IDE编译。维基百科
