Standard converters often struggle with modern operating systems or specific memory alignment issues. The v2.3 patch addresses several critical bottlenecks:
ImageConverter 565 (often associated with Henning Karlsen's UTFT library imageconverter 565 v23 patched
: Processes common image formats including BMP , JPG , and PNG . Copied to clipboard Implementation Tips Displaying the Image
Microcontrollers often lack the processing power to decode complex image formats like JPEG or PNG in real-time. ImageConverter 565 bridges this gap by "pre-decompressing" images into a raw byte array. or AVR projects.
When the tool converts an image, it outputs a data array similar to this: // Generated by : ImageConverter 565 v2.3 (Patched) // Image Size : 128x128 pixels // Memory usage : 32768 bytes uint16_t myImage[ ] PROGMEM = { // ... [Raw RGB565 Pixel Data] Use code with caution. Copied to clipboard Implementation Tips Displaying the Image : Use library-specific commands like myGLCD.drawBitmap(x, y, width, height, myImage) if using the UTFT library Naming Restrictions
Improved handling of transparent PNGs and their conversion to a specific background hex color.
: Outputs image data as a .c source file containing a const unsigned short array, which can be directly included in Arduino, chipKit, or AVR projects.
