| mbed_official | 237:f3da66175598 | 38 | DMA Tx/Rx Channel. |
| mbed_official | 237:f3da66175598 | 39 | |

| mbed_official | 237:f3da66175598 | 45 | __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process. |
| mbed_official | 237:f3da66175598 | 46 | -@- Make sure that either: |
| mbed_official | 237:f3da66175598 | 47 | (+@) I2S clock is configured based on SYSCLK or |
| mbed_official | 237:f3da66175598 | 48 | (+@) External clock source is configured after setting correctly |
| mbed_official | 237:f3da66175598 | 49 | the define constant EXTERNAL_CLOCK_VALUE in the stm32f3xx_hal_conf.h file. |
