#   This python converts an rgb value expressed in 8 bit values (eg 255, 128, 0) and returns a hex value that
#   has been converted to 565 format. This was highly useful when I was playing with some Arduino
#   stuff requiring 16 bit LCD designs and couldn't remember the hex layout. 

def rgb_hex565(red, green, blue):
    # take in the red, green and blue values (0-255) as 8 bit values and then combine
    # and shift them to make them a 16 bit hex value in 565 format. 
    print ("0x%0.4X" % ((int(red / 255 * 31) << 11) | (int(green / 255 * 63) << 5) | (int(blue / 255 * 31))))

For me it gave the wrong value, changing around the red and blue values. Changing blue to red and red to blue did the job for me. This was for my 1.8`128x160 RGB TFT LCD display. By the way, thanks for the code.

Ty it still helps people (like me)

Thank You, bit shifting has been a challenge for me.
