1.54 and 2.9 Not compiling in Arduino IDE 1.8.13
As in the title this examples are not compiling in Arduino IDE. I got: avr/pgmspace.h: No such file or directory I found https://www.arduino.cc/reference/en/language/variables/utilities/progmem/ which says this library is already included in modern IDE so I tried to comment #include <avr/pgmspace.h> and I got: pgm_read_byte' was not declared in this scope I would appreciate some informations about how to make this displays work!
This header file should already be included in the project and is shipped with the IDE by default. Please add the detailed error information.
I have come across this issue and resolved it temporarily by adding the library to the working folder and getting rid of the "avr/" in my "include" lines.
