esp-idf-lib VS ESP8266Audio

External libraries are added as 'components'. I suggest you take a look at the great work by UncleRus et al, you can add the repository as a git submodule and add the items you want to use as a 'REQUIRES' statement in your CMakeLists.txt file.

The library by UncleRus has an example and it mentions you should (and this probably is right).

The library is: https://github.com/UncleRus/esp-idf-lib and the example uses the DHT (Humidity sensor) library.

My first idea to solve this was to create my component which implements a mutex to access each I2C bus. Now, when I was searching github for previous implementations, I saw this repo https://github.com/UncleRus/esp-idf-lib. Not only does it have the solution for I2C it also has components for some of the sensors I am using.

With some research found out the library actually works correctly when run outside of platformio with idf.py as stated here: https://github.com/UncleRus/esp-idf-lib/issues/46

Having an issue here using the ESP8266 Audio library (found here).

The Arduino sketch that works for me reads the data out of PROGMEM. When I use that same raw data in ESPhome, it crashes my ESP too. Would there be a way to play from PROGMEM in ESPhome too? Other ways in the library are a function or streaming, but that doesn't fit my use case unfortunately.

If you're getting started, the ESP8266Audio library makes it easy to play audio with the Arduino toolchain. For more advanced use cases, Espressif's own ESP-ADF has a lot of useful features and examples.

Not sure where you got that. According to the ESP8266Audio documentation, the default GPIOs are 2, 15, and 3. You're trying to change 15 to 13.

ESP8266Audio is really fun and easy to use

The ESP32 might suffice for that then, depending on what you consider to be basic applications. It certainly has wifi and bluetooth functionality and you can do audio with an extra chip or an interesting workaround. The ESP32-A1S module even has the necessary chip integrated but you'll likely need to roll a custom PCB for it.

I am simply using the sample code from here. https://github.com/earlephilhower/ESP8266Audio
