Hi,
I am trying to use a circular DMA to transfer ADC samples on STM32L4R9VI.
I configured a 3.2 Msps sampling frequency, which means that HAL_ADC_ConvCpltCallback and HAL_ADC_ConvHalfCpltCallback must be called each 10 ms for a 64000 elemets buffer.
However, i measured the interval between each callback and it gave 10 us ...
The following screenshorts are for DMA and ADC config

Show the code that actually sets up and starts the conversion.
