Byte Ordering: Most systems use "Big Endian" or "Little Endian." If your colors look swapped (e.g., red looks blue), you likely need to toggle this setting.

ImageConverter 565 v2.3 is a lightweight, efficient tool designed to convert standard images into raw data arrays (usually .c or .h files) that a microcontroller can read and push directly to a display buffer. Key Features of v2.3

  1. C/C++ Header (const uint16_t): Standard for Arduino and embedded C projects.
  2. Python List/Tuple: For MicroPython and CircuitPython implementations.
  3. Raw Binary (.bin): For storage on external SD cards or SPI Flash memory (fatfs).

Step-by-Step Guide: How to Use ImageConverter 565 v2.3

Let's walk through converting a 24-bit PNG logo into a C array for an Arduino project driving a 128x64 TFT display.

Goals

  • Produce high-quality RGB565 output from common image formats (PNG, JPG, GIF, WEBP).
  • Support configurable dithering, resize/filtering, and alpha premultiplication or thresholding.
  • Provide CLI, library API (C/C++ and Python), and an optional GUI.
  • Minimize dependencies; target cross-platform builds (Windows, macOS, Linux) and embedded toolchains.
