7. Betjeningsvejledning

7.1. Programming the Board

Once your development environment is set up, you can upload your code to the Vision Master E213. Select the correct board model (ESP32-S3 Dev Module or similar) and COM port in your IDE. Use the provided examples or develop your own code to utilize the Wi-Fi, Bluetooth, LoRa, and E-Ink display functionalities.

7.2. E-Ink Display Usage

The 2.13-inch E-Ink display is designed for low-power, static information display. Full refreshes can take a few seconds. Avoid frequent full refreshes to prolong the display's lifespan. Partial updates may be supported by specific libraries for faster, localized changes.

7.3. LoRa Communication

The integrated SX1262 LoRa chip supports long-range, low-power communication. Configure LoRa parameters such as frequency (902-928MHz for this model), spreading factor, bandwidth, and coding rate according to your application and regional regulations. The board is compatible with LoRaWAN and Meshtastic protocols.

7.4. Batteristyring

The board's battery management system handles charging and discharging of a connected 3.7V lithium battery. Monitor battery levels through software to optimize power usage and ensure reliable operation in portable applications.

8. Vedligeholdelse

• Rensning: Use a dry, soft cloth to clean the board. Avoid using liquids or solvents.
• Opbevaring: Opbevar printpladen et tørt og antistatisk sted, når den ikke er i brug.
• Håndtering: Handle the board by its edges to avoid touching components, especially the E-Ink display, which can be delicate.
• Firmwareopdateringer: Regularly check for updated firmware or libraries from the manufacturer or community to ensure optimal performance and access to new features.

9. Fejlfinding

• Board ikke fundet: Ensure USB Type-C cable is properly connected. Install necessary USB-to-serial drivers. Try a different USB port or cable.
• Uploadfejl: Verify that the correct board and COM port are selected in your IDE. Ensure no other application is using the serial port. Check for syntax errors in your code.
• E-Ink Display Not Updating: Confirm display libraries are correctly installed and initialized. Check power supply to the display. E-Ink displays have a slower refresh rate; allow sufficient time for updates.
• LoRa-kommunikationsproblemer: Ensure the LoRa antenna is securely connected. Verify LoRa parameters (frequency, spreading factor, etc.) match between devices. Check for interference in the operating frequency band.
• Battery Not Charging/Powering On: Ensure the battery is correctly connected to the SH1.25-2 interface. Check battery voltage. Verify USB power source is sufficient.
