| Setting | Register Command (example) | Effect | |---------|----------------------------|--------| | RGB565 | 0x3A (Interface Pixel Format) = 0x55 | 16-bit/pixel | | RGB888 | 0x3A = 0x66 | 24-bit/pixel |
const unsigned char image_logo_mono[] = 0xAA, 0x55, 0xFF, ... // 1 bit per pixel, packed ;
For example, with the TFT driver, the following registers are crucial for correct orientation: image2lcd register code work
Select the color format your LCD requires (usually 16-bit RGB565 for TFT). Step 3: Generate the Code
Image2Lcd is a widely used Windows utility that converts standard images (BMP, JPEG, GIF) into hexadecimal pixel data arrays. Embedded system developers use this data to display graphics on LCD, OLED, and TFT screens controlled by microcontrollers like Arduino, STM32, or ESP32. | Setting | Register Command (example) | Effect
// Write image data – handle byte ordering tft.startWrite(); for (int i = 0; i < 240*320; i++) uint16_t color = (img[i*2] << 8) tft.endWrite();
Sets the physical pixel dimensions of the output array. 3. How the Code Works Across Color Depths Embedded system developers use this data to display
No byte-swapping loops – the register code ensures the LCD expects the exact memory layout.
