Subject: Analysis of Embedded Graphics Asset Preparation and RGB565 Conversion Version: 2.3 Date: October 26, 2023 Abstract ImageConverter 565 v2.3 is a specialized utility designed to bridge the gap between high-fidelity graphic design software and resource-constrained embedded systems. As modern microcontrollers (MCUs) and TFT displays become ubiquitous in IoT and consumer electronics, the need to translate standard 24-bit or 32-bit image formats into the memory-efficient RGB565 format is critical. This paper outlines the functional architecture of v2.3, its algorithmic approach to color reduction, the implementation of the RLE compression engine, and its role in the embedded development workflow. 1. Introduction In the realm of embedded GUI development (utilizing libraries such as LVGL, Adafruit GFX, or TFT_eSPI), memory is often the primary bottleneck. Standard image formats (PNG, JPEG, BMP) utilize 24-bit True Color (RGB888) or higher, consuming significant RAM and Flash storage. The RGB565 format represents a standard compromise between color depth and data size, fitting a pixel into just 16 bits (2 bytes). Pppe227 Asuna Hoshi Un020234 Min Top Apr 2026
