rgb565 to rgb888 and back

There is https://gamebuino.com/academy/reference/gb-createcolor for going from rgb888 to rgb565. 

I see rgb565Torgb888 in Misc.cpp to go the other way, but I'm guessing it was written assuming it would only be used internally in the library.

I'd like to add that rgb888 -> rgb565 has dataloss, as we are downsampling a 24-bit cilor to a 16-bit one

Thats no problem.

I have an ESP32 with a OV7670 Camera. 

The Camera only outputs RGR565, but for me its easier to work with RGB888 Values.

Well, you can always use the method aoniell pointed out by pre-declaring it.

EDIT:

something like this should do (untested):

#include <utils/Misc.h>

// and then
Gamebuino_Meta::RGB888 rgb = Gamebuino_Meta::rgb565Torgb888(0x1234);

rgb.r; // red
rgb.g; // green
rgb.b; // blue
