I2S Analog Output Test

This is a simple basic test for the ESP32 analog output using I2S.

We just send a generated sine wave and expect to hear a clean signal. Please note the log level should be set so that there is no disturbing output!

Output Device: Piezo Electric Element

To test the output I am using a piezo electric element

DAC

It should also be possible to connect a headphone to the output pins...

On the ESP32 the output is on the Pins GPIO26 and GPIO27

PIEZO ESP32
+ GPIO25 / GPIO26
- GND
