2. سیٹ اپ ہدایات
This section outlines the basic steps to prepare your Raspberry Pi Pico for use.
2.1 مطلوبہ اجزاء
- Raspberry Pi Pico board (included)
- Micro USB cable (not included)
- USB پورٹ والا کمپیوٹر
- Optional: Breadboard, jumper wires, headers for prototyping.
2.2. Initial Firmware Installation
- کمپیوٹر سے جڑیں: دبائیں اور تھامیں۔ بوٹسل button on the Pico. While holding, connect the Pico to your computer using a Micro USB cable. Release the BOOTSEL button once connected.
- Access USB Mass Storage: Your computer should recognize the Pico as a mass storage device named "RPI-RP2".
- Drag and Drop Firmware: Download the desired firmware file (e.g., MicroPython UF2 file) from the official Raspberry Pi website. Drag and drop this UF2 file onto the "RPI-RP2" drive.
- ریبوٹ: The Pico will automatically reboot, and the "RPI-RP2" drive will disappear. The new firmware is now installed.

3. آپریٹنگ ہدایات
Once firmware is installed, you can begin programming and interacting with your Raspberry Pi Pico.
3.1. Programming Environments
- MicroPython: A lean and efficient implementation of the Python 3 programming language optimized for microcontrollers. Thonny IDE is a recommended tool for MicroPython development on Pico.
- C/C++ SDK: For advanced users, Raspberry Pi provides a comprehensive C/C++ Software Development Kit (SDK) for direct programming.
3.2. GPIO Pin Usage
The Pico features 26 multi-function GPIO pins that can be configured for various purposes, including digital input/output, analog input, PWM, I2C, SPI, and UART communication.

Refer to the official Raspberry Pi Pico documentation for detailed pin assignments and programming examples for specific functionalities.
4 دیکھ بھال
Proper care ensures the longevity and reliable operation of your Raspberry Pi Pico.
- ماحولیاتی تحفظ: Keep the Pico in a dry environment, away from moisture, extreme temperatures, and direct sunlight.
- الیکٹروسٹیٹک ڈسچارج (ESD): Handle the board by its edges to minimize the risk of ESD damage. Consider using an anti-static mat and wrist strap when working with sensitive electronic components.
- صفائی: اگر ضروری ہو تو بورڈ کو نرم، خشک برش یا کمپریسڈ ہوا سے آہستہ سے صاف کریں۔ مائعات یا کھرچنے والے مواد کے استعمال سے پرہیز کریں۔
- جسمانی تحفظ: Consider using an enclosure for your projects to protect the Pico from physical damage and dust.
5 خرابیوں کا سراغ لگانا
This section addresses common issues you might encounter with your Raspberry Pi Pico.
5.1. عام مسائل اور حل
- Pico not recognized as "RPI-RP2":
- Ensure the BOOTSEL button is held down while connecting the USB cable.
- Try a different Micro USB cable and USB port on your computer.
- Verify the cable is a data cable, not just a charging cable.
- Code not running:
- نحوی غلطیوں کے لیے اپنا کوڈ چیک کریں۔
- Ensure the correct firmware (e.g., MicroPython) is installed.
- Verify that your programming environment (e.g., Thonny) is correctly configured to communicate with the Pico.
- External components not working:
- تمام وائرنگ کنکشنز کو دو بار چیک کریں۔
- Ensure external components are powered correctly and within the Pico's voltage حدود.
- Verify the GPIO pins are configured correctly in your code (input/output, pull-ups/downs).
