Problems with Bitmaps on TFT Display using GFX Library

david_prentice:
You have declared the array as in SRAM

//Main bitmap images stored in Bitmaps.c

extern uint8_t MainTFTDisplayBitmap[];  //Main Background Image



add the const qualifier and it will use the correct overloaded drawBimap() method:

//bitmap in PROGMEM
   drawBitmap(int16_t x, int16_t y, const uint8_t bitmap[],
     int16_t w, int16_t h, uint16_t color),
   //bitmap in SRAM
   drawBitmap(int16_t x, int16_t y, uint8_t *bitmap,
     int16_t w, int16_t h, uint16_t color),

Edit. Your bitmap uses 2560 bytes which is not too expensive.
However you could probably draw the lines and print the text with regular GFX graphics methods. It depends on whether you are using that particular font elsewhere.

That was it! Thanks so much I actually tried defining it as a const at one point but it didnt help, idk I guess I did it wrong lol. Again thank you so much for the quick reply! Below is the updated code portion.

extern const uint8_t MainTFTDisplayBitmap[];  //Main Background Image
