#include "logo.h" display_set_window(0, 0, 127, 63); display_write_data((uint8_t*)logo_data, sizeof(logo_data)); Note the cast to uint8_t* if your driver expects byte streams. Once you master basic conversions, leverage these advanced capabilities of ImageConverter 565 v2.3. 1. Using the CLI for Automated Builds Add this to your Makefile or PlatformIO script:
So, download ImageConverter 565 v2.3, feed it your next sprite sheet, and watch your embedded UI come to life—one pixel-perfect 16-bit word at a time. Have you used ImageConverter 565 v2.3 in a unique project? Share your experience in the comments below, or contribute to the open-source community by writing a wrapper script for your favorite build system. imageconverter 565 v2.3
// Generated by ImageConverter 565 v2.3 const unsigned short logo_data[8192] = // 128*64 = 8192 pixels 0x0000, 0x0010, 0x8420, 0xFFFF, ... ; Copy this file into your embedded project’s source tree. In your display driver, write the array sequentially to the framebuffer or directly to the display via SPI: #include "logo
Enter —a niche but powerful utility that has become a quiet industry standard for converting standard images into raw RGB 565 data. Whether you are programming an STM32, working with an ESP32 driving a small display, or developing firmware for a wearable device, understanding this tool can save you hours of manual pixel manipulation. Using the CLI for Automated Builds Add this
In the world of embedded systems, mobile graphics, and low-power display drivers, every single bit matters. While modern smartphones handle 4K HDR video effortlessly, developers working with microcontrollers, OLEDs, or TFT screens often operate under severe memory and bandwidth constraints. This is where specialized tools become indispensable.
| Tool | Key Feature | Limitation | |------|-------------|-------------| | | Simple, fast, batch+CLI | Windows-only GUI | | LVGL Image Converter | Online web tool, supports multiple color formats | Requires internet, limited file size | | GIMP with export script | Full editing suite | Complex setup, not purpose-built | | Python PIL script | Infinite flexibility | Must write and maintain code |
Whether you are displaying a company logo on a smartwatch or rendering a weather icon on an off-grid sensor node, mastering this tool will dramatically streamline your workflow. By understanding RGB 565 encoding, leveraging dithering, and correctly handling byte ordering, you can produce sharp, memory-efficient visuals that feel surprisingly vibrant despite the 16-bit limitation.
