Hey guys, I've been struggling for days, my screen works fine on the Arduino Uno, no problem there.
But I can't get any output on the Mega 2560.
I'm attaching the code and images below; could you please take a look, coding experts?
#include <ILI9486_SPI.h> //Hardware-specific library
#if (defined(TEENSYDUINO) && (TEENSYDUINO == 147))
ILI9486_SPI tft(/*CS=*/ 10, /*DC=*/ 15, /*RST=*/ 14);
// for my wirings used for e-paper displays:
#elif defined (ESP8266)

//ILI9486_SPI tft(/*CS=D8*/ SS, /*DC=D4*/ 2, /*RST=D3*/ 0); // my proto board for RPi display
#elif defined(ESP32)

#elif defined(ARDUINO_ARCH_SAMD)
// mapping suggestion for Arduino MKR1000 or MKRZERO
// note: can't use SS on MKR1000: is defined as 24, should be 4
// BUSY -> 5, RST -> 6, DC -> 7, CS-> 4, CLK -> 9, DIN -> 8 // my e-paper connector
ILI9486_SPI tft(/*CS=*/ 4, /*DC=*/ 7, /*RST=*/ 6); // to my proto board
