ImageConverter 565 v2.3 automates the complex mathematical bit-shifting required to downsample 24-bit images into this efficient 16-bit space. Step-by-Step Conversion Workflow
If you created a .raw file, you can load it in Arduino using:
#include // Initialize display (Model, MDA, TCL, CLK, CS, RST) UTFT myGLCD(ILI9341_S5P, 11, 13, 10, 8, 9); // Include your converted image file extern unsigned short myImage_320x240[76800]; void setup() myGLCD.InitLCD(); myGLCD.clrScr(); void loop() // Draw the image at coordinate X=0, Y=0 myGLCD.drawBitmap(0, 0, 320, 240, myImage_320x240); delay(5000); Use code with caution. Method 2: Using Adafruit_GFX and TFT_eSPI
Scaling your assets to the exact pixel dimensions of your screen (e.g., 320x240). Bit-Reduction: imageconverter 565 v2.3
Option 2: The Technical Deep-Dive (Best for a Blog/Tutorial)
is a specialized utility developed by Rinky-Dink Electronics designed to convert standard image files (like .BMP, .PNG, or .JPG) into high-performance data arrays for use with microcontrollers like Arduino and chipsets such as the TTGO . It is particularly popular among hobbyists and engineers working with small TFT/LCD screens that require the RGB565 color format. Key Functions and Features

// Example of how the output looks in your code const uint16_t myImage[76800] PROGMEM = 0x0000, 0xFFFF, 0xABCD, ... ; // Drawing it to the screen tft.pushImage(0, 0, 240, 320, myImage); Use code with caution. Why Version 2.3 Matters for Modern Devs If you want, I can generate: ImageConverter 565 v2
Perfect for directly embedding image data into your microcontroller's flash memory.
is a foundational utility designed to bridge this gap. Initially popularized by Henning Karlsen’s legendary UTFT Library , this specific tool converts standard desktop graphics into raw 16-bit RGB565 data.
Converting 24-bit color to 16-bit color can sometimes cause "banding" artifacts in gradients. Version 2.3 utilizes optimized dithering algorithms to smooth out transitions, ensuring your converted graphics look as close to the original source as possible. 2. Multi-Format Output Support
If using the and tinyFAT libraries, you would move the .raw file onto an SD card and use the following code structure: Bit-Reduction: Option 2: The Technical Deep-Dive (Best for
