What is the pixel format for Raspberry Pi framebuffer Looks like the unsigned char pointer was actually casting to unsigned char and thus truncating the data to only 8 bits, 5 of which were blue, and 3 were . I tried comparing the /boot/config. Welcome to the Raspberry Pi Framebuffer Graphics repository! This repository provides a simple tutorial, example, and code snippets to help you get started with low graphics development using the How can one find the addresses for things like the frame buffer using official docs without relying on tutorials? I'd like to know so I'll be able to find them and other useful relevant information. The Depth of a framebuffer is the number of bits in every pixel.
