I2s adc

Use both readings in buffer.
Simplified the math.
Created a global variable to hold the collected result (should make it easier to integrate)

whats the sample rate in this example ?

Sorry but in ESP32 Arduino2.0.2 this code can no longer use on my ESP32-WROOM. the Serial Output Says that:

Could you please help me figure out this question? I'm new to ESP32 on Arduino, so I just want to study ADC with DMA by look through the example program.

This is not the place to bring up issues. Please fill out an issue report. Be sure to decode the backtrace for that report.
