This example reads audio data from an Invensense's ICS43432 I2S microphone
|
||
|
|
breakout board, and prints out the samples to the Serial console. The
|
||
|
|
Serial Plotter built into the Arduino IDE can be used to plot the audio
|
||
|
|
data (Tools -> Serial Plotter)

Circuit:
|
||
|
|
* Arduino/Genuino Zero, MKR family and Nano 33 IoT
|
||
|
|
* ICS43432:
|
||
|
|
* GND connected GND
|
||
|
|
* 3.3V connected to 3.3V (Zero, Nano, ESP32), VCC (MKR)
|
||
|
|
* WS connected to pin 0 (Zero) or 3 (MKR), A2 (Nano) or 25 (ESP32)
|
||
|
|
* CLK connected to pin 1 (Zero) or 2 (MKR), A3 (Nano) or 5 (ESP32)
|
||
|
|
* SD connected to pin 9 (Zero) or A6 (MKR), 4 (Nano) or 26 (ESP32)
