RGB888 to RGB565 / Bit Shifting

Question

I want to combine three characters into a short using bit shifting. This is for implementing the RGB565 color palette (where there are 5 bits for red, 6 for green, 5 for blu

Thanks for A2A. I had also faced the same issue. The below code would help you.

unsigned int r,g,b; // Pixel data in the RGB
unsigned char x1,x2; // The container for resulting 2 bytes

x1 = (r & 0xF8) | (g >> 5); // Take 5 bits of Red component and 3 bits of G component

x2 = ((g & 0x1C) << 3) | (b  >> 3); // Take remaining 3 Bits of G component and 5 bits of Blue component

You can find the python program in the GIThub. https://github.com/ajay126z/RGB888ToRGB565-Converter
