2. Орнотуу нускамалары
This section outlines the basic steps to prepare your Raspberry Pi Pico for use.
2.1. Керектүү компоненттер
- Raspberry Pi Pico board (included)
- Micro USB cable (not included)
- USB порту бар компьютер
- Optional: Breadboard, jumper wires, headers for prototyping.
2.2. Initial Firmware Installation
- Компьютерге туташуу: басып, кармап туруңуз BOOTSEL 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".
- Микропрограммалык камсыздоону сүйрөп таштоо: 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.
- Кайра жүктөө: The Pico will automatically reboot, and the "RPI-RP2" drive will disappear. The new firmware is now installed.

3. Иштөө нускамалары
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. Техникалык тейлөө
Proper care ensures the longevity and reliable operation of your Raspberry Pi Pico.
- Курчап турган чөйрөнү коргоо: Keep the Pico in a dry environment, away from moisture, extreme temperatures, and direct sunlight.
- Электростатикалык разряд (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.
- Тазалоо: If necessary, gently clean the board with a soft, dry brush or compressed air. Avoid using liquids or abrasive materials.
- Физикалык коргоо: Consider using an enclosure for your projects to protect the Pico from physical damage and dust.
5. Кыйынчылыктарды
This section addresses common issues you might encounter with your Raspberry Pi Pico.
5.1. Жалпы маселелер жана чечүү жолдору
- 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:
- Бардык зым байланыштарын эки жолу текшериңиз.
- Ensure external components are powered correctly and within the Pico's voltage чектөөлөр.
- Verify the GPIO pins are configured correctly in your code (input/output, pull-ups/downs).
