check MADCTL register in ili9341.
u need to invert x axis also seems colors are wrong.
madctl register contains RGB BGR setting.
so check pdf. here is function call that u need to use (or simular one ) to fix ur problem.


void MACONTROL(bool MY,bool MX,bool MV,bool ML,bool BGR,bool MH)
{
volatile uint8_t data=(MY<<7) | (MX<<6) | (MV<<5) |(ML<<4)|(BGR<<3)|(MH<<2);
writecommand(ILI9341_MADCTL);
writedata(data);
}
