ADC+DMA fills all the buffer when calling to HAL_ADC_ConvHalfCpltCallback()

[JLope.11]

In a stm32f303rb76, I commanded to operate ADC+DMA by setting of the

ADC DMA with circular mode

The ADC I activated continuous conversion mode

and DMA continuous request

Also the analog input signal (no scan mode)

In the initialization made following command:

HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adc1_buf, 2*ADC_BUF_LEN);

Then in the debug mode I realized that always calls:

HAL_ADC_ConvHalfCpltCallback()

filling all the buffer (not a half)

But never calls to HAL_ADC_ConvCpltCallback()

it is a problem of the debugger?

How can be solved?

Hello @JLope.11​, 

Could you specify the processor frequency? the ADC frequency? clock prescaler and resolution?
