img2rgb565

A command-line tool that converts image files to RGB565 format C arrays for embedded systems and displays.

Features

• Converts images to 16-bit RGB565 format
• Generates paired .c/.h files with uint16_t arrays
• Supports BMP, JPEG, PNG, and GIF formats
• Optimized for embedded graphics applications

Build

# Using Make
make build

# Using Go directly
go build

Usage

./img2rgb565 image.png

This generates:

• image.c - Array definition with RGB565 pixel data
• image.h - Header file with extern declaration

Example

$ ./img2rgb565 logo.png
# Creates logo.c and logo.h

# In your C code:
#include "logo.h"
// Use img_logo[] array (16-bit RGB565 values)
