I have a code that uses the adafruit libraries with the giga r1 and display shield. The code compiles and uploads fine but the screen is blank. I have tried using the examples and most don't do anything to the screen. I can get some examples to work but once adafruit libraries are included, nothing works. Has anyone experienced this before and if so, how did you fix it? The code I have looks perfect on paper but it just won't display properly.
#include <Adafruit_GFX.h> // Include Adafruit GFX library

// Initialize the display (adjust the pins as needed)
