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

[Snara.21]

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 be added for calculation

2. The below is DMA Setting

 

Added DMA Setting as ADC1

 

In STM32Cube MX if the PCLK2/Prescalar value is 64 MhZ Which is 0.016 us

Total sampling time is therefore:

= 24.5 * 0.016 us = 0.392 us

Sample Rate = 1/.392 which is 2.55 MHz.

1. Kindly confirm the calculation is correct
