Image2lcd Register Code Work Now

The Curious Case of the Pixel Puzzle

Meet Sam. Sam had just bought a small graphic LCD screen—a tiny 128x64 pixel monochrome display. Sam wanted to show a small logo: a happy ghost icon.

• The LCD screen is divided into pages (horizontal strips). For a 128x64 monochrome screen, there are 8 pages (each page is 8 pixels tall).
• Each page has 128 columns. Each column needs one byte (8 bits) sent to a register.

// Example: Parse Image2LCD output for LCD register commands
typedef struct 
    uint8_t reg_addr;
    uint8_t reg_value;
 lcd_reg_t;
When you write an image to an LCD, you are essentially performing three steps over SPI, I2C, or parallel interface: The LCD screen is divided into  pages  (horizontal strips)
void LCD_DrawImage(uint16_t x, uint16_t y, uint16_t w, uint16_t h, const uint16_t *data) 
    // Step 1: Set column address register (0x2A)
    LCD_WriteReg(0x2A, x);          // Start column
    LCD_WriteReg(0x2A, x + w - 1);  // End column
// Step 2: Set row address register (0x2B)
LCD_WriteReg(0x2B, y);          // Start row
LCD_WriteReg(0x2B, y + h - 1);  // End row
Image2Lcd is a popular Windows-based utility used by electronics hobbyists and engineers. It converts standard image files (like BMP, JPEG, or GIF) into C-array code or binary data that microcontrollers can use to display images on LCD or OLED screens.
