ADC DMA isnt designed for one sample buffer, or better say your complete callback cant be more instruction cycles as one conversion when you set one as buffer = next not practical chaos

Your code is in IRQ and next IRQ arrive = stop working

Hello
I am using STM32G030 but my question is not specific to G series

How can I view the number of ADC conversions per second?

For example I can put Counter++ in (DMA circular )HAL_ADC_ConvCpltCallback And get it in seconds using a timer?

The G030 has a 12-bit ADC with 2Ms/s

ADC clock of 32 MHz divided by 2 = 16 MHz (12.5 + 1.5) should be 1.1Msample/s? is not it?

Is this practical?

Your question is not practical. ADC have docu and on init you define speed of conversion .

Some years ago i here ask why MX not shown this values , when ADC is configured. I mean still not show, then you need calc this. For example

I am testing it right now
When I put ADC_SAMPLETIME_160CYCLES_5, the counter shows the number 92486. But when I set it to ADC_SAMPLETIME_79CYCLES_5, it stops working
