Audio Example

This example plays a 440 Hz tone through espp::Audio at a few volumes and then muted, on an I2S amplifier with no codec (e.g. a MAX98357A), so the volume and mute are applied in software.

The default pins (menuconfig, Example Configuration) are the LilyGo T-Deck’s: BCLK 7, WS 5, data out 6, with its peripheral power rail (GPIO 10) switched on first.

How to use example

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
