Image2lcd Register Code -
For a 128×160 RGB565 image: (128 × 160 × 16) / 8 = 40,960 bytes — exactly the size shown in the example.
The Image2LCD register code consists of a series of bytes, each with a specific meaning. The first byte typically represents the register address, which indicates the specific function or setting being controlled. The subsequent bytes contain the data to be written to the register.
void display_on() // Set the display control register to display on uint8_t reg_code = DISPLAY_CONTROL_REGISTER; uint8_t data = DISPLAY_ON; image2lcd register code
SSD1306 (OLED) typically uses Horizontal — MSB First (scan code 0x00 ), while ST7789 (TFT) in certain modes expects Vertical — LSB First (scan code 0x01 combined with bit5=1). Matching the wrong scan mode to the wrong LCD driver produces pixel soup.
The trial version of Image2Lcd is functionally restricted. Unregistered versions enforce a strict output size limit, typically capping the generated array at or truncating the data array. If you attempt to convert a larger image (such as a 320x240 or 480x320 display asset), the software outputs incomplete data, resulting in corrupted or cut-off visuals on your physical screen.

Image2LCD supports batch processing for multi-image projects, such as icon sets or UI assets. Advanced compression strategies include Run-Length Encoding (RLE), which can significantly reduce flash memory usage for images with large uniform areas. Selecting RLE or similar compression in the output settings will automatically generate decompressible data in the C array.
Register code can update a window. Set the LCD's column/address pointers via commands before sending data. Example:
