`adafruit-ampy` is a Python tool that allows you to interact with MicroPython-based boards, such as the Raspberry Pi Pico, over a serial connection. It provides a way to manage files on the board, upload Python scripts, and perform various file-related operations.
Here's how you can use `adafruit-ampy` with your Raspberry Pi Pico W to interact with it over the serial port:
Make sure you have Python installed on your computer. You can then install `adafruit-ampy` using pip, the Python package manager:
- pip install adafruit-ampy
Connecting Your Raspberry Pi Pico
Connect your Raspberry Pi Pico to your computer using a USB cable. You might need to install drivers, depending on your operating system.
Find the Serial Port
You'll need to identify the serial port that your Pico is connected to. On Linux and macOS, you can often find this information by running:
- ls /dev/tty*
Look for a port that represents your Pico (e.g., `/dev/ttyUSB0` on Linux or `/dev/tty.usbmodem` on macOS). You can also easily find this in Thonny on the bottom right.
Once you have `adafruit-ampy` installed and your Pico connected, you can use it to manage files on the Pico. Here are some common commands:
To list files on the Pico:
- ampy --port /dev/ttyUSB0 ls
To upload a file to the Pico:
- ampy --port /dev/ttyUSB0 put your_file.py
To download a file from the Pico:
- ampy --port /dev/ttyUSB0 get remote_file.py local_file.py
To remove a file from the Pico:
- ampy --port /dev/ttyUSB0 rm your_file.py
To run a Python script on the Pico:
- ampy --port /dev/ttyUSB0 run your_script.py
Replace `/dev/ttyUSB0` with the actual serial port of your Pico.
Remember that `adafruit-ampy` assumes that your Pico is running MicroPython firmware. If you haven't installed MicroPython on your Pico, you'll need to do that first.
