| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Display shows random pixels/blocks | Incomplete initialization or floating I/O pins | Ensure all unused pins are tied to GND or defined as outputs via software | | Severe flicker at low temperatures | Temperature compensation not enabled | Set the internal temperature sensor register (0x3F) to "Auto Mode" | | Inability to write to full frame buffer | Using "Lite" version libraries | Access the extended memory registers (0x80 - 0xFF) only available in the Full variant | | Overheating at 5V operation | Internal regulator dissipation | Switch to 3.3V logic or add a heatsink to the exposed pad |
The "Full" version contains a more complex register map. A proper initialization sequence should include: icdv30096ero full
