DrawXBitmap issue/confusion

[sparx266]

OK, I’m trying to use this sketch:

https://github.com/CelliesProjects/moonPhase-esp32/blob/master/examples/esp32/ILI9341/ILI9341.ino

But with TFT_eSPI instead of Adafruit_ILI9341.

The pictures are stored as RGB565 (16-bit) but TFT_eSPI expects an 8 bit value here.
Is this correct?
What is the best way around this please?

Thanks and regards.

The library can handle that image type with the pushImage function. Just replace the functions so instead of:

tft.drawRGBBitmap( 100, 20, (uint16_t *)phase_000.pixel_data, 80, 80);
use:
tft.pushImage( 100, 20, 80, 80, (uint16_t *)phase_000.pixel_data);

Thanks Bodmer, but that didn't quite do it.
The image is displayed but its not as clear as in the original code.
Is there anything else that could be causing this issue?

I expect the colours are "byte swapped".
Add this line to the end of setup():

tft.setSwapBytes(true);

That's got it.

Thank you so much.
