: Uncheck this unless your driver specifically requires a header. 2. Register Logic Example
void setup() tft.init(); tft.setRotation(0); // The exact method for writing a block of data depends on your library // Often, you can push a 16-bit color array directly to the screen. // tft.pushImage(0, 0, 128, 128, (uint16_t*)gImage_image);
For STM32, the process integrates seamlessly with the standard HAL libraries.
Select the format your screen driver expects (e.g., RGB565 for TFT). image2lcd register code
To apply this code and remove the watermark from your converted images, follow these steps: Open the program on your computer [5].
While Image2LCD is the established standard, developers seeking cross-platform or open-source solutions may consider alternatives.
void LCD_SetAddressWindow(uint16_t x0, uint16_t y0, uint16_t x1, uint16_t y1) // Column Address Set (CASET) LCD_WriteCommand(0x2A); LCD_WriteData(x0 >> 8); LCD_WriteData(x0 & 0xFF); LCD_WriteData(x1 >> 8); LCD_WriteData(x1 & 0xFF); // Row Address Set (RASET) LCD_WriteCommand(0x2B); LCD_WriteData(y0 >> 8); LCD_WriteData(y0 & 0xFF); LCD_WriteData(y1 >> 8); LCD_WriteData(y1 & 0xFF); // Memory Write (RAMWR) - Tells LCD that pixel data is coming next LCD_WriteCommand(0x2C); Use code with caution. 2. Pushing the Image2Lcd Array to Register : Uncheck this unless your driver specifically requires
If your reds appear blue, switch the byte ordering or change your display driver configuration from RGB to BGR mode.
By following the controller-specific workflows outlined above—from parameter selection to integration with register-level drivers—any embedded developer can eliminate guesswork from LCD image display, accelerate development cycles, and consistently achieve correct results, whether the target is a full-color TFT powered by ILI9341, a monochrome OLED driven by SSD1306, or a compact display based on ST7735.
Under in Image2LCD, select your color depth. For C array output, the generated code will look like: // tft
Toggle the "Reverse Color" checkbox in Image2Lcd before exporting.
When you convert an image, Image2Lcd outputs a C array. Depending on your settings, it looks like this:
What are you using (e.g., ILI9341, ST7789, ST7735)?
Displays read memory in either RGB or BGR sequence depending on the Memory Access Control register ( 0x36 ). You can fix this by changing the 3rd bit of register 0x36 in your init code, or by changing the sampling format option dropdown inside Image2Lcd.
The software will only convert the first few lines of your image. For example, if you try to convert a 240x240 icon, it might stop compiling data after the 40th row.
