T-Deck firmware v4.7a

#1

I just grabbed the latest T-Deck firmware from [https://github.com/technoblogy/ulisp-tdeck]. When I try to compile it in Arduino, I get:

Compilation error: I2S.h: No such file or directory

Which library do I need to add to the sketch?
There’s an ESP_I2S.h in the esp32 package, but it doesn’t seem to be compatible. When I search for I2S in the Library Manager, there are about 10 choices, so I’m not sure which one to use.

Thanks,
Dennis

Never mind. The Arduino software had auto-updated my ESP32 board library from version 2.0.14 to 3.1.1. (Apparently any version beyond 2.0.14 will not work.)
