Resolved! How to test real ADC frequency and its accuracy?

Hi guys, I'd like to test if the true ADC frequency is the same as what I've set. The ADC setting is HSI14 (14 MHz) as clock source, 12 bits resolution (corresponds to 12.5 ADC clock cycles), sampling time is 1.5 clock cycles. Therefore, one conversi...
