I’ve been working with small TFT or monochrome LCDs (like ILI9341, ST7789, or SSD1306) and using to convert bitmap images into C-style arrays. However, the "register code" it generates can be confusing if you're not sure how to interface it with your MCU's driver.
// Example: Sending register code from Image2LCD void LCD_Send_Init_Sequence(uint8_t *cmd_list, uint8_t len) { for (int i = 0; i < len; i++) { uint8_t cmd = cmd_list[i++]; uint8_t data = cmd_list[i]; LCD_Write_Command(cmd); // Pull RS low (CMD) LCD_Write_Data(data); // Pull RS high (DATA) delay_ms(5); // Some registers need settling time } } image2lcd register code
// Register code (CMD, DATA) 0x01,0x00, // Software Reset 0x11,0x00, // Exit Sleep 0x3A,0x55, // Pixel Format (16-bit) 0x36,0x48, // Memory Access (RGB/BGR order) 0x2A,0x00,0x00,0x00,0xEF, // Column Address Set 0x2B,0x00,0x00,0x00,0xEF, // Page Address Set 0x29,0x00 // Display ON Do not just paste this into your main loop. You need to send it to your LCD via SPI/I2C. Here’s a typical driver flow: I’ve been working with small TFT or monochrome
// Your Image2LCD generated list const uint8_t init_code[] = { 0x01,0x00, 0x11,0x00, 0x3A,0x55, 0x29,0x00 }; You need to send it to your LCD via SPI/I2C
You can adjust the tone depending on where you post it. Understanding the Register Code Generated by Image2LCD (Bitmaps to MCU Display)
