ILI9361 tft mirrored flip image

[yoroboticscolombia]

HI, is there any way or register to invert ili9361, I get mirrored image, i have tried different rotation opcions but does not, its esp32,

Thanks.

Check if you are using tft.setRotation(0); try tft.setRotation(6); which is the X-Mirror of (0)

Thanks, the ili9361 has only rotation 3, in the options, is there anyway to update,

// This is the command sequence that rotates the ILI9163 driver coordinate frame

rotation = m % 4;

writecommand(TFT_MADCTL);
switch (rotation) {
case 0:
writedata(TFT_MAD_MX | TFT_MAD_MY | TFT_MAD_BGR);
_width = _init_width;
_height = _init_height;
#ifdef CGRAM_OFFSET
colstart = 0;
rowstart = 0;
#endif
break;
case 1:
writedata(TFT_MAD_MV | TFT_MAD_MY | TFT_MAD_BGR);
_width = _init_height;
_height = _init_width;
#ifdef CGRAM_OFFSET
colstart = 0;
rowstart = 0;
#endif
break;
case 2:
writedata(TFT_MAD_BGR);
_width = _init_width;
_height = _init_height;
#ifdef CGRAM_OFFSET
colstart = 0;
rowstart = 32;
#endif
break;
case 3:
writedata(TFT_MAD_MX | TFT_MAD_MV | TFT_MAD_BGR);
_width = _init_height;
_height = _init_width;
#ifdef CGRAM_OFFSET
colstart = 32;
rowstart = 0;
#endif
break;
}

writedata(TFT_MAD_MX) make the display Mirror-X, which case you are using ?

[yoroboticscolombia]

MX

thanks, I used all 3 cases, but no success,

Are you using ILI9163 library?, you say you have ILI9361 chip right ? From the picture that should be the ILI9341 chip.

yes, its the only one that has good resolutuion, 9341 has blurry pixels.

I have no idea why that happens, so at this time just try to edit the library for your case. Try to edit tft.setRotation(0) and remove the TFT_MAD_MX.

 case 0:
      writedata(TFT_MAD_MY | TFT_MAD_BGR);
      _width  = _init_width;
      _height = _init_height;
	  #ifdef CGRAM_OFFSET
        colstart = 0;
        rowstart = 0;
	  #endif
      break;

      break;

Thanks, I Will try tomorrow and tell you, since I did not understand the registers of the display in the datasheet,

The library supports the ILI9163, I assume there is a type in your driver number?

Assuming that is the case then it the flip settings in the MADCTL register need to be changed by experiments. Once changed for rotation use a setRotation(x) command immediately after tft.init to make sure the setting overrides the default init.

The control bits MX, MY, MV flip the x,y and vertical coordinates.
