Image2lcd Register Code Work -

const unsigned char image_data[] = 0xF8, 0x00, // Red in RGB565 = 0xF800 0x07, 0xE0 // Green = 0x07E0 ; But your LCD’s write routine expects 16-bit values via SPI in (low byte first). Your register code must include a byte-swap loop:

// ILI9341 init sequence 0x01, // Software reset 0x11, // Sleep out 0x36,0x48, 0x3A,0x55, ... Then your main code can loop through this sequence without writing separate register functions. However, many advanced users disable this option because their existing LCD driver already handles register setup. image2lcd register code work

tft.setAddrWindow(0, 0, 240, 320);

// Write image data – handle byte ordering tft.startWrite(); for (int i = 0; i < 240*320; i++) img[i*2+1]; tft.writePixel(color); const unsigned char image_data[] = 0xF8, 0x00, //

void LCD_DrawImage(const unsigned char* data, int width, int height) for (int i = 0; i < width * height; i++) data[i*2+1]; // if big-endian // Or swap: pixel = data[i*2] However, many advanced users disable this option because
