2. سيٽ اپ جون هدايتون
This section outlines the basic steps to prepare your Raspberry Pi Pico for use.
2.1. گهربل جزا
- Raspberry Pi Pico board (included)
- Micro USB cable (not included)
- ڪمپيوٽر کي يو ايس بي پورٽ سان
- Optional: Breadboard, jumper wires, headers for prototyping.
2.2. Initial Firmware Installation
- ڪمپيوٽر سان ڳنڍيو: کي دٻايو ۽ رکو بوٽيل 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.
- ريبوٽ: The Pico will automatically reboot, and the "RPI-RP2" drive will disappear. The new firmware is now installed.

3. آپريٽنگ هدايتون
Once firmware is installed, you can begin programming and interacting with your Raspberry Pi Pico.
3.1. Programming Environments
- مائڪرو پائيٿون: 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. سار سنڀال
Proper care ensures the longevity and reliable operation of your Raspberry Pi Pico.
- ماحولياتي تحفظ: Keep the Pico in a dry environment, away from moisture, extreme temperatures, and direct sunlight.
- Electrostatic Discharge (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.
- صفائي: جيڪڏهن ضروري هجي ته، بورڊ کي نرم، سڪل برش يا دٻيل هوا سان نرميءَ سان صاف ڪريو. مائع يا رگڙيندڙ مواد استعمال ڪرڻ کان پاسو ڪريو.
- جسماني تحفظ: Consider using an enclosure for your projects to protect the Pico from physical damage and dust.
5. مسئلا حل ڪرڻ
This section addresses common issues you might encounter with your Raspberry Pi Pico.
5.1. عام مسئلا ۽ 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:
- Check your code for syntax errors.
- 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:
- سڀني وائرنگ ڪنيڪشن کي ٻه ڀيرا چيڪ ڪريو.
- Ensure external components are powered correctly and within the Pico's voltage حدون.
- Verify the GPIO pins are configured correctly in your code (input/output, pull-ups/downs).
