Error compiling for board M5Stack-Core-ESP32.
Not sure what to do, I have tried to write those paths in but I still am getting error. Not sure what to do. Code is as follows. I'm sure its a simple fix but this is the first time I am using arduino and 32.
Also, where do I get and put the font files? In the same file as the ino? Or is there somewhere else I need to get and put them? I already downloaded the gfx file and I feel like that it should be working, but its not.
