2.3 Første tilslutning

1. Ensure the ON/OFF switch on the board is in the 'OFF' position.
2. Connect the development board to your computer using a standard USB cable (Micro-USB to USB-A).
3. Flip the ON/OFF switch to the 'ON' position. The power LED (if present) should illuminate.
4. Your computer should detect the board as a serial device. You may need to install specific drivers depending on your operating system and development environment. Refer to the Holyiot website or your chosen SDK documentation for driver installation instructions.

3. Betjeningsvejledning

The Holyiot nRF54L DK is a development board, meaning its primary function is to allow users to program and test custom firmware. The operation largely depends on the software development kit (SDK) and tools you choose.

3.1 Grundlæggende funktionalitet

• Magt: The board can be powered via the USB port (5.0V) or external 3.3V/5.0V sources through the dedicated pin headers.
• GPIO'er: The numerous pin headers provide access to the nRF54L15's General Purpose Input/Output pins, allowing connection to external sensors, actuators, and other peripherals.
• Knapper og lysdioder: The onboard buttons (BUTTON0-3) and LEDs (LED0-3) are directly connected to GPIOs and can be used for basic user interaction and status indication in your applications.
• Nulstil: The RESET button allows for a hardware reset of the nRF54L15 module.

3.2 Programming and Debugging

The board supports programming and debugging via the SWDIO and SWDCLK pins, typically using a compatible programmer/debugger (e.g., J-Link, ST-Link) and an appropriate IDE (e.g., Segger Embedded Studio, VS Code with extensions). Consult the nRF54L15 documentation and your chosen SDK for detailed programming instructions.

3.3 Trådløs kommunikation

The integrated nRF54L15 module supports Bluetooth 6.0 Low Energy (BLE) and other multi-protocol technologies. You can develop applications for various wireless communication scenarios, including:

• BLE advertising and scanning
• GATT client/server roles
• Mesh netværk
• Other proprietary protocols supported by the nRF54L15

4. Vedligeholdelse

To ensure the longevity and proper functioning of your development board, follow these general maintenance guidelines:

• Opbevaring: Store the board in a dry, anti-static environment, away from direct sunlight and extreme temperatures.
• Rensning: Brug en blød, tør klud til at rengøre pladen. Undgå at bruge væsker eller slibende rengøringsmidler.
• Håndtering: Handle the board by its edges to avoid touching sensitive components. Static electricity can damage electronic components, so use anti-static precautions when handling.
• Strømforsyning: Always use a stable and appropriate power supply (5.0V via USB or specified voltage via headers).

5. Fejlfinding

5.1 Board Not Recognized by PC

If your computer does not detect the development board when connected via USB:

• Tjek USB-kabel: Ensure the USB cable is fully inserted and not damaged. Try a different USB cable and port on your computer.
• Afbryderen: Verify that the ON/OFF switch on the board is in the 'ON' position.
• Drivere: The most common issue is missing or incorrect drivers. Install the necessary USB-to-serial drivers for your operating system. These are often provided by the chip manufacturer (e.g., FTDI, Silicon Labs) or as part of the nRF Connect SDK.
• Strømforsyning: Ensure the board is receiving adequate power. The power LED should be illuminated.
• Genstart: Try restarting your computer and reconnecting the board.

5.2 Firmware Upload Failure

• Programmer Connection: Ensure your programmer/debugger (e.g., J-Link) is correctly connected to the SWDIO, SWDCLK, VDD, and GND pins.
• Softwarekonfiguration: Double-check your IDE and programming tool settings (e.g., target device, interface speed).
• Magt: Ensure the board is powered on during the programming process.
