picox 1.1.4

Tools for working with a Rasbperry Pi Pico running MicroPython

picox

picox is a tool that facilitates the interaction with Raspberry Pi Pico running MicroPython boards through the terminal or within a Python script. This uses the USB serial port for communication.

Windows, Linux and macOS are supported.

Features

• Detect a connected Raspberry Pi Pico device running MicroPython
• REPL session
• File operations: Upload, download, execute, and list files on Pi Pico
• Stop current execution on device

Known issues

• REPL can timeout on long operations such as sleep. Its in the nature of how it scans for the end
• Line endings of files coming out can get a little strange. watch out if there are som extra spaces etc. Best bet is to ensure you always work in the same line endings
• File operations do not include folder operations yet

Installation

Install via pip:

pip install picox

CLI Usage

Detecting Pi Pico:

# get first found device
picox detect

# get a list of all connected pico devices
pico detect --all

# Output: COM7 or /dev/ttyUSB0

REPL session on Pi Pico

picox repl /dev/ttyUSB0

Listing files on Pi Pico:

picox ls /dev/ttyUSB0

# exmaple output:
# demo.py
# home.py

Uploading a file:

picox upload /dev/ttyUSB0 local.py remote.py --overwrite

# --overrite to force update the file on the Pi Pico

Downloading a file:

picox download /dev/ttyUSB0 remote.py local.py

Executing a file on Pi Pico:

picox exec /dev/ttyUSB0 remote.py

Stopping any ongoing operation on Pi Pico:

picox stop /dev/ttyUSB0

Python Script Usage

You can also use picox within your Python scripts as follows:

from picox import Pico
from picox.detect import get_first_pico_serial


# Init device
serial_device = get_first_pico_serial()
pico = Pico(serial_device)

# File listing
for file in pico.get_file_list():
    print(file)

# Download
with open("./local/demo.py", "w") as download_file:
    pico.download_file("remote_demo.py", download_file)

# Upload
with open("./local/demo.py", "rb") as upload_file:
    pico.upload_file(upload_file, "remote_demo.py", overwrite=True)

# Execute
pico.execute_file("remote_demo.py")

# Halt execution on device
pico.stop_exec()

# Soft reboot device
pico.send_soft_reboot()
