ADC + DMA for Analog Microphone. I am using Sensortile.BOx STEVAL - MKSBOX1V1 Kit. 1. Is sampling rate for Calculation is correct 2. I have configured DMA + ADC - Kindly confirm whether configuration is ok. 3. How to read DMA Data and send to UART

ADC Sampling rate :-Total Conversion Time (Tconv) = Samplingtime + 12 (This 12 is for 12-bit resolution of ADC). If I set 12.5 Cycles in MX based on the settings of the controller STM32L9RI My ADCCLK Cycle will be =24.5 . Please confirm whether 12 to...
