Introduction

Pass arguments to code files by writing them to a file before launching.

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-argv-file

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-argv-file

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-argv-file

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install adafruit_argv_file

Or the following command to update an existing version:

circup update

Usage Example

import supervisor

from adafruit_argv_file import write_argv

write_argv("argv_file_otherfile.py", [42, "CircuitPython is Cool", None, [1, 2, 3]])

print("Launching: argv_file_otherfile.py")
supervisor.set_next_code_file("argv_file_otherfile.py")
supervisor.reload()

argv_file_otherfile.py

from adafruit_argv_file import read_argv

args = read_argv(__file__)
print(args)
