1. Driver Installation (CP2102)

Before connecting your ESP8266 ESP-12E Development Board to your computer, you may need to install the CP2102 USB to UART Bridge VCP Drivers. These drivers enable your computer to recognize the board as a serial port.

• Download the appropriate CP2102 driver for your operating system (Windows, macOS, Linux) from the official Silicon Labs webalan.
• Follow the installation instructions provided with the driver package.
• After installation, connect the board to your computer using a Micro USB cable. Verify that a new COM port appears in your device manager (Windows) or system information (macOS/Linux).

2. Arduino IDE Setup

The ESP8266 ESP-12E can be programmed using the Arduino IDE. Follow these steps to prepare your IDE:

• Download and install the latest version of the Arduino IDE.
• Open the Arduino IDE and go to File > Tercihler.
• In the 'Additional Boards Manager URLs' field, add the following URL: http://arduino.esp8266.com/stable/package_esp8266com_index.json
• Git Tools > Board > Boards Manager.... Arama 'ESP8266' and install the 'esp8266 by ESP8266 Community' package.
• Once installed, go to Araçlar > Pano and select 'NodeMCU 1.0 (ESP-12E Module)'.
• Select the correct COM port for your board under Araçlar > Bağlantı Noktası.

3. Pin Şeması

Understanding the pinout is crucial for connecting external components and programming. Refer to the diagram below for the pin assignments of the ESP8266 ESP-12E Development Board.

Kullanım Talimatları

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() tamamlar.
• To upload code, click the 'Upload' button in the Arduino IDE. The CP2102 interface will handle the flashing process automatically.

2. Wi-Fi Bağlantısı

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.

Bakım

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

• Dikkatli Kullanın: Tahtayı düşürmekten veya aşırı fiziksel strese maruz bırakmaktan kaçının.
• Statik deşarj: Always handle the board in an anti-static environment or take precautions to prevent electrostatic discharge, which can damage electronic components.
• Temizlik: 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.
• Depolamak: Panoyu kuru, serin bir ortamda, doğrudan güneş ışığından ve aşırı sıcaklıklardan uzakta saklayın. Uzun süre saklayacaksanız antistatik poşetler kullanın.
• Güç Kaynağı: Ensure you use a stable 5V power supply. Incorrect voltagtahtaya zarar verebilir.

Sorun giderme

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 kablosu: Try a different Micro USB cable. Some cables are for charging only and do not support data transfer.
• USB Bağlantı Noktası: Kartı bilgisayarınızdaki farklı bir USB bağlantı noktasına bağlayın.
• 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.
• Test Pimleri: 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 Araçlar > Pano Arduino IDE'de.
• 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.
• Güç Kaynağı: Ensure your power supply is stable and provides sufficient current, especially when connecting multiple peripherals.
