我看你配置的代码都禁用了全双工，其实STM32F407的I2S是完全支持全双工的。


比方：

static void MX_I2S2_Init(void)
{


  hi2s2.Instance = SPI2;
  hi2s2.Init.Mode = I2S_MODE_MASTER_RX;
  hi2s2.Init.Standard = I2S_STANDARD_PHILIPS;
  hi2s2.Init.DataFormat = I2S_DATAFORMAT_24B;
  hi2s2.Init.MCLKOutput = I2S_MCLKOUTPUT_ENABLE;
  hi2s2.Init.AudioFreq = I2S_AUDIOFREQ_48K;
  hi2s2.Init.CPOL = I2S_CPOL_LOW;
  hi2s2.Init.ClockSource = I2S_CLOCK_PLL;
  hi2s2.Init.FullDuplexMode = I2S_FULLDUPLEXMODE_ENABLE;
  if (HAL_I2S_Init(&hi2s2) != HAL_OK)
  {
    Error_Handler();
  }

我按这个配置后发现主时钟输出是不对，采用HAL_I2S_Receive_DMA(&hi2s2,(uint16_t*)adc_buf,2048);也无法接收到数据

[md]如果你要做全双工，配置就是这样的。

至于你说的时钟问题，那就看你的具体设计了。
