DMA double buffer Interrupt

Hi all, I have a STM32 NUCLEO-H743ZI evaluation board. I am trying to read ADC using DMA. Meanwhile, I also need to use the CPU to process the data read from the ADC. So I use a double buffer mode. 

I used CubeMX to generate the framework of the code. Then I modified a bit to enable the double buffer mode. I tried to use the functions HAL_ADC_ConvHalfCpltCallback and HAL_ADC_ConvCpltCallback. However, seems like they are being called at the same frequency.

My question is: Can I get an interrupt when the Buffer1 is filled while Buffer 2 is being filled? If yes, is there any actions I should take?

My question is similar to this thread:

'Here's essentially what I'd like to happen:

1.) Buffer 0 fills

2.) interrupt occurs (I service Buffer 0)

3.) Buffer 1 fills

4.) interrupt occurs (I service Buffer 1)

5.) repeat 1 through 4'
