I was working with HAL library for STM32F4 for I2S interface. In particular with this version file:

  * @file    stm32f4xx_hal_i2s_ex.c

  * @author  MCD Application Team  * @version V1.4.2  * @date    10-November-2015

using this version I was having HAL_I2S_RxHalfCpltCallback when I2S is configured in circular mode. It's very usefull callback.

Now I'm working with an updated version of HAL and that file version is:

  * @file    stm32f4xx_hal_i2s_ex.c

  * @author  MCD Application Team  * @version V1.7.1  * @date    14-April-2017

I notice that there is no HAL_I2S_RxHalfCpltCallback. Where do I find information about this changes?

Hello

Garberoglio.Leon

,

This call back has been replaced by I2SEx_TxRxDMAHalfCplt and

HAL_I2SEx_TxRxHalfCpltCallback

to be compliant with HAL coding rules.

So, you need just to rename your old callabck by the new one:

HAL_I2SEx_TxRxHalfCpltCallback.

Hope this helps you.

With Regards,

Imen
