Scale your image file to the exact pixel resolution of your physical target display (e.g., 240x320 or 128x128). Save the file as a .png format to preserve original color clarity. 2. Configure the Output Parameters
This ensures your images are always up-to-date when you compile.
Double-check that your loop function uses the exact width and height parameters as the exported asset. Conclusion imageconverter 565 v2.3
and other microcontrollers to convert standard image files (like .BMP, .JPG, or .PNG) into RGB565 formatted arrays for display on TFT LCD screens Purpose and Function
is designed to transform your graphics into memory-efficient formats for use with Arduino, chipKit, and other microcontroller platforms. Version 2.3 includes improved stability and optimized array generation for high-speed display libraries. Key Conversion Steps Prepare Your Image Scale your image file to the exact pixel
The conversion from a standard image to an RGB565 array involves a color space transformation. The tool reads each pixel's red, green, and blue values from the source, then of each channel to 5, 6, and 5 bits respectively.
Ensure your array declaration includes the PROGMEM keyword (for AVR chips like Arduino Uno/Mega). This forces the image to stay inside the larger Flash memory rather than consuming precious volatile RAM. Distorted or Diagonal Lines Configure the Output Parameters This ensures your images
Why use when there are many free online converters available? The answer lies in the specific output format. Generic tools, like those found on imageconverter.dev, are excellent for converting between standard formats for everyday use but do not generate C arrays for microcontrollers.
is a software utility designed to convert standard image formats like PNG and JPEG into RGB565 image data. This specific version was likely part of the tooling ecosystem for the UTFT (Universal TFT) library, a popular library for driving TFT displays with Arduino and other microcontrollers. The RGB565 color format is a standard for many display drivers in the embedded world.
