HAL_I2C_MasterTxCpltCallback for second i2c

I am using both I2Cs in my board. Also, using DMA for non-blocking.

HAL_I2C_Master_Transmit_DMA generates interrupt for completion (also for reception and error.

HAL only allows for one ''weak'' callback for both.

Is there away to name my callback functions (complete/error ...) for each I2C in order to separate logic for each I2C?

Thanks.

Hi alsaleem.ahmad,

You may add a check on I2C instance in the CallBack function then implement what you need depending on the instance.
