5. செயல்பாட்டு வழிகாட்டி
Operating the Waveshare 2.13-inch E-Paper module involves programming your Raspberry Pi Pico to send display data via the SPI interface. Waveshare provides example code and libraries to facilitate this process.
5.1 Programming the Display
- Access Development Resources: Visit the official Waveshare product page or documentation portal for the Pico-ePaper-2.13 module. Here you will find example code in C/C++ and MicroPython.
- நூலகங்களை நிறுவவும்: Download and install any necessary libraries or drivers for your chosen programming language (e.g., MicroPython libraries for e-paper displays).
- எக்ஸ்-ஐ ஏற்றவும்ample குறியீடு: Upload the provided example code to your Raspberry Pi Pico. These examples typically demonstrate basic functions like displaying text, images, or performing partial/full refreshes.
- உள்ளடக்கத்தைத் தனிப்பயனாக்கு: Modify the example code to display your desired content. Pay attention to the display resolution (250x122 pixels) and color depth (black/white, 2 grey scales).
- Refresh Cycles: Understand the difference between full refresh (approx. 2 seconds) and partial refresh (approx. 0.3 seconds). Partial refresh is faster and consumes less power but may leave ghosting artifacts over time, requiring an occasional full refresh.
5.2 விண்ணப்பம் Exampலெஸ்

6. பராமரிப்பு மற்றும் பராமரிப்பு
To ensure the longevity and optimal performance of your Waveshare E-Paper display module, follow these maintenance guidelines:
- கவனத்துடன் கையாளவும்: E-paper displays are delicate. Avoid applying excessive pressure or bending the module, especially the flexible FPC cable.
- சுத்தம்: Use a soft, dry, lint-free cloth to gently wipe the display surface. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the screen.
- சுற்றுச்சூழல் நிலைமைகள்: Operate and store the module within its specified temperature and humidity ranges. Avoid extreme temperatures, direct sunlight for prolonged periods, and high humidity.
- சக்தி மேலாண்மை: While the display retains content without power, ensure proper power-down sequences for the Raspberry Pi Pico to prevent data corruption or unexpected behavior.
- நிலையான மின்சாரம்: Take precautions against electrostatic discharge (ESD) when handling the module, as electronic components can be sensitive to static.
7. சரிசெய்தல்
If you encounter issues with your E-Paper display module, consider the following troubleshooting steps:
- Display Not Refreshing/Blank:
- Check all connections between the E-Paper module and the Raspberry Pi Pico. Ensure they are secure and correctly oriented.
- Verify the power supply to the Raspberry Pi Pico.
- Review your code for display initialization and refresh commands. Ensure the SPI interface is correctly configured.
- Confirm that the correct libraries for the Pico-ePaper-2.13 are installed and imported in your code.
- Ghosting or Image Retention:
- Ghosting is common with partial refreshes. Perform a full refresh periodically to clear the display completely.
- Ensure your refresh cycles are correctly implemented in your code.
- தவறான காட்சி நோக்குநிலை:
- The display typically operates in portrait mode by default. If you require landscape orientation, check if your chosen library or example code supports rotation and how to implement it.
- Module Not Detected by Pico:
- Double-check the pin connections against the pinout diagram (Figure 7).
- Ensure the Raspberry Pi Pico is functioning correctly independently.
