#define BLUE 0x001F /* 0, 0, 255 */ tft.fillScreen(BLUE); Why?

Hi @brightproject , Maybe used GREENTAB or default nothing in InitR? Try tft.initR(INITR_BLACKTAB); in void setup section. tadamx

GREENTAB - initialisation GOOD, but image shifted. I corrected file Adafruit_ST7735.cpp

//madctl = ST77XX_MADCTL_MX | ST77XX_MADCTL_MY | ST7735_MADCTL_BGR;
madctl = ST77XX_MADCTL_MX | ST77XX_MADCTL_MY | ST77XX_MADCTL_RGB;

Did you mean BLACKTAB? Because your corrected version of Adafruit_ST7735.cpp would cause BLACKTAB colors to be used. It would also cause the image to be shifted if it is the same display type as in #191 and #154.
