Image2lcd Register Code Work -

: For 16‑bit color, 0 = 5‑5‑5, 1 = 5‑6‑5 format.

Each register holds 8 bits (8 pixels in a row). The LCD scans these registers one by one to turn pixels on or off. image2lcd register code work

The function extracts the dimensions directly from the Image2LCD header (bytes 2-5) and sets a display window using the GRAM command 0x2C , which enables the LCD controller to auto-increment its internal address pointer as it receives sequential pixel data [10†L19-L21][11†L10-L11]. : For 16‑bit color, 0 = 5‑5‑5, 1 = 5‑6‑5 format

The output array generated by Image2Lcd acts as the raw payload that you must write directly into the display's internal frame memory (GRAM) via its control registers. The function extracts the dimensions directly from the

Customizable scanning directions (horizontal, vertical, top-to-bottom, bottom-to-top).

Raw register code can be large (150KB for QVGA). Image2LCD does not compress by default, but you can add RLE (Run Length Encoding) in post-processing, then decode on the fly using a small routine that writes to the data register.

For example, on STM32 with LTDC or SPI DMA:
