1,首先到GITHUB下载「ESP32-audioI2S」 https:///schreibfaul1/ESP32-audioI2S/ 2,解压。 3,把解压的文件放进Arduino IDE的libraries文件夹 接线 MAX98357与单片机接线如下: VIN --- 5V GND---GND DIN---25 BCLK---27 LRC---26 这里注意esp32开发板在arduino框架下,34 35 36 39 脚只能作为输入,将...

I2S协议 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...

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....
I'm using a ESP32 as I2S Master to feed a Teensy 4.1 with Bluetooth Audio. It worked fine for more than 100 hours than bluetooth started with noise and failed working 2 hours later. ESP32 can still be programmed but bluetooth is not avaiable any more. Same behavior with a spare part...
API使用:在ESP-IDF中,常用i2s_driver_install()初始化I2S+DMA,通过i2s_write()或i2s_read()操作数据。 示例配置步骤(伪代码逻辑): 初始化I2S参数(模式、采样率、位宽)。 分配双DMA缓冲区(如每个缓冲区1024字节)。 启动I2S驱动,启用DMA传输。 在中断或任务中循环填充/读取缓冲区数据。
