The ESP32-LyraTD-MSC has six buttons (Set, Play, Rec, Mode, Vol- and Vol+) that are connected through a ladder of resistors to ADC 1, channel 3 of the ESP32. A status of these buttons may be read by the application using a dedicated API "ADC Button" and then used to control the application flow.
The purpose of this application is to provide a simple demonstration how to read the status of buttons as well as a quick verification that all buttons are operational.
