// 3. Power Control (Register 0xC0) LCD_WriteCommand(0xC0); LCD_WriteData(0x23); // VRH[5:0]
| Problem | Likely Cause | Solution | |---------|--------------|----------| | Image displays garbled colors | Wrong color format (RGB565 vs RGB888) | Change Image2LCD output format | | Image mirrored or rotated | Incorrect register 0x36 (Memory Access Control) | Pre-rotate in Image2LCD or adjust MY , MX , MV bits | | Image shifts right/left | Column address register misconfigured | Verify start column matches array stride | | Slow drawing | No use of address auto-increment | Ensure you don’t re-send column/row per pixel | | Flicker | Writing to data register too slow | Use SPI max speed or parallel interface |
