Imageconverter 565 V2.3 2021 Site

If your reds appear blue or the image looks like a photo negative, the byte order is swapped. Re-convert the image in v2.3 and toggle the checkbox, or check if your display initialization requires an inversion command like tft.invertDisplay(true) . Memory Overflow Errors

| 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 |

Version 2.3 introduces several optimizations over older legacy releases:

Double-check your resolution dimensions. If the code expects a 320x240 image but your array contains data for a 319x240 image, every row of pixels will shift, causing a diagonal distortion pattern. imageconverter 565 v2.3

A single 320x240 image in 24-bit color requires 230 KB of RAM/Flash. An Arduino Uno only has 32 KB of Flash total.

For versions integrated with UTFT, the process was likely more visual and GUI-driven, with options to select output type and array formatting.

Select RAW (for SD card) or C Array (for compilation into firmware). Click Convert: The tool will generate the output file. 3. Integrating with UTFT (SD Card Method) If your reds appear blue or the image

Add this to your Makefile or PlatformIO script:

Because the images are already in raw format, the microcontroller does not need to decompress JPG or PNG files on the fly. It can read the data and send it directly to the display, enabling high-speed animations and fast screen refreshes.

This guide covers everything you need to know to master version 2.3, optimize your graphic workflows, and display vibrant visuals on TFT and OLED screens. What is ImageConverter 565 v2.3? If the code expects a 320x240 image but

#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

Note: The PROGMEM keyword forces the array into Arduino’s Flash memory instead of burning through valuable dynamic RAM (SRAM). Step 4: Draw to Screen
