3.7 esp 32 family

esp-32-controllers have an i²c-interface and an wifi interface as well. The actual implementation uses the i²c-inteface. But feel free to implement the wifi RESTapi.

• All GPIO-ports of your esp-32-controller could be used as i²C-interface. Connect SDA, SCL and GND with the ftcSoundBar i²c interface.
• You don't need a evel shifter, since both boards are based on 3.3V logic levels.
• Download ftcSoundBar.zip from this repo.
• Add this library to your Arduino IDE using Sketch/Include File/Add zip-library.
• You might add the correct SDA and SCL ports to the library.
• Checkout the example application via FILE/EXAMPLES/FTCSOUNDBAR/FTCSOUNDBARDUINO
• A detailed description of the Arduino API is described in ...

Remarks:

• See chapter 1 for a description of the ftcSoundBar's i²c connector.
