When trying to setup for Streaming Database and Updating States in the Firebase Webapp book I get an error In file included from .pio/libdeps/esp-wrover-kit/Adafruit GFX Library/Adafruit_GrayOLED.cpp:20:0:
.pio/libdeps/esp-wrover-kit/Adafruit GFX Library/Adafruit_GrayOLED.h:30:32: fatal error: Adafruit_I2CDevice.h: No such file or directory
I think all the includes are there and there doesn’t seem to be a problem in the main cpp.
Has anyone seen this?
I wonder what I’ve done wrong?
Any help would be greatly appreciated.
In the Libraries menu search for “adafruit BusIO” and add it to your project.
Let me know if this solves the issue.
