Naudojimo instrukcijos

1. Basic Programming

Once the Arduino IDE is set up, you can write and upload your code. The board functions similarly to other Arduino-compatible boards:

• Code placed in the setup() function runs once at startup.
• Code in the loop() function executes repeatedly after setup() užbaigia.
• To upload code, click the 'Upload' button in the Arduino IDE. The CP2102 interface will handle the flashing process automatically.

2. WiFi ryšys

The ESP8266 is designed for WiFi applications. You can connect it to your local network and use it to send or receive data, host web servers, or interact with cloud services. Libraries like the ESP8266WiFi library in Arduino IDE simplify network operations.

Priežiūra

To ensure the longevity and optimal performance of your KeeYees ESP8266 ESP-12E Development Board, follow these maintenance guidelines:

• Elkitės atsargiai: Venkite lentos numetimo ir per didelio fizinio krūvio.
• Statinė iškrova: Always handle the board in an anti-static environment or take precautions to prevent electrostatic discharge, which can damage electronic components.
• Švara: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids or harsh chemicals.
• Saugykla: Plokštę laikykite sausoje, vėsioje vietoje, toliau nuo tiesioginių saulės spindulių ir ekstremalių temperatūrų. Jei laikote ilgesnį laiką, naudokite antistatinius maišelius.
• Maitinimas: Ensure you use a stable 5V power supply. Incorrect voltaggali pažeisti plokštę.

Trikčių šalinimas

1. Board Not Recognized / No COM Port

If your computer does not detect the board or a COM port is not available in the Arduino IDE:

• Check CP2102 Driver: Ensure the CP2102 driver is correctly installed. Reinstall it if necessary.
• USB kabelis: Try a different Micro USB cable. Some cables are for charging only and do not support data transfer.
• USB prievadas: Connect the board to a different USB port on your computer.
• Restart IDE/Computer: Close and reopen the Arduino IDE, or restart your computer.

2. Incorrect Digital Pin Behavior

If digital pins are not behaving as expected (e.g., D0-D8 labels not matching GPIO in code):

• Consult Pinout: Always refer to the detailed pinout diagram (provided in the Setup Guide) and official NodeMCU ESP-12E documentation to confirm the actual GPIO numbers corresponding to the D-labels.
• Bandymo kaiščiai: Use simple blink sketches to test individual pins and verify their functionality.

3. Board Stuck in Boot Loop / Upload Errors

If the board continuously reboots or you encounter errors during code upload:

• Correct Board Selection: Ensure 'NodeMCU 1.0 (ESP-12E Module)' is selected under Įrankiai > Lenta Arduino IDE aplinkoje.
• Erase Flash: Sometimes, corrupted firmware can cause issues. Use the 'ESP8266 Sketch Data Upload' tool or a dedicated flash tool to erase the board's flash memory before uploading new code.
• Add Delay: When developing, consider adding a short delay (e.g., delay(1000);) at the beginning of your setup() function. This can provide a window to upload new code if the board enters a rapid boot loop.
• Maitinimas: Ensure your power supply is stable and provides sufficient current, especially when connecting multiple peripherals.
