I2S 和 I2C 一样都是由飞利浦于上世纪八十年代推出的经典接口,于 1996 年定版,专门传输芯片之间的数字音频数据,主要用于 Codec、Audio PA、DSP 等。 标准I2S有3个主要信号: 串行时钟BCLK,帧时钟LRCLK,串行数据SDATA。串行时钟BCLK也叫位时钟,即对应数字音频的每一位数据。帧时钟LRCLK用于切换左右声道的数据。LRCLK...

启动audio_pipeline时,会为pipeline中的所有Elements创建Tasks。 audio_pipeline_register(pipeline, mp3_decoder, “mp3”); audio_pipeline_register(pipeline, i2s_stream_writer, “i2s”); audio_pipeline_link(pipeline, (const char *[]) {“mp3”, “i2s”}, 2); ...

I found the examples from the wiki with this board that has a revised audio example based on the i2s_es8311 example code that supposedly has the correct setup. Even when using this code I am still unable to get any audio from the board. I am really not sure what the issue could be....
