Problem with adafruit gfx

Life would be much simpler if you posted your actual code.

I just had to write something from scratch:

#include <MCUFRIEND_kbv.h>
MCUFRIEND_kbv tft;

#include <Fonts/FreeMono18pt7b.h>

#define BLACK       0x0000
#define WHITE       0xFFFF

void setup(void)
{
    tft.begin(tft.readID());
    tft.fillScreen(BLACK);
    tft.setCursor(15, 100);
    tft.setTextColor(WHITE);
    tft.setFont(&FreeMono18pt7b);
    tft.setTextSize(1);
    tft.print("I m here !!!");
}

void loop(void)
{
}

And it worked just fine.

Incidentally, if you want to post a photo, why do you post it upside down?
