I am trying to play with an Adafruit 16x8 Led Matrix. But when I try to compile an example program, I get the following error message:
In file included from .pio\libdeps\uno\Adafruit GFX Library_ID13\Adafruit_SPITFT.cpp:36:0:
.pio\libdeps\uno\Adafruit GFX Library_ID13\Adafruit_SPITFT.h:26:17: fatal error: SPI.h: No such file or directory
I am gathering that SPI.h is another Library that I need to include with in my project along with the Adafruit GFX Library and the Adafruit LED Backpack Library.
When I search for the SPI.h library, I get a bunch of hits, but none of the library’s seem to be for i2c communication with the Adafruit Led Backpack.
What am I missing?
