samps

A hypermodern, type-safe, zero-dependency Python library for serial port I/O access.

Installation

pip install samps

or

using your preferred environment / package manager of choice, e.g., poetry, conda or uv:

poetry add samps

conda install samps

uv add samps

Usage

The general usage of this library is to create a serial connection to the device you want to communicate with.

You'll need to know the serial port name and the baudrate of the device you want to communicate with, this is usually found in the device's documentation.

Once you have the serial port name and baudrate, you can create a SerialCommonInterface (or SerialAsyncCommonInterface) object and use it to communicate with the device as follows:

from samps import SerialCommonInterface as Serial

serial = Serial(port="/dev/tty.usbserial-0001", baudrate=9600)

serial.open()

print(["Serial Port Is Open?", "Yes" if serial.is_open() else "No"])

line = serial.readline()

print(line.decode("utf-8").strip())

serial.close()

print(["Serial Port Closed"])

or, using a context manager:

from samps import SerialCommonInterface as Serial

with Serial(port="/dev/tty.usbserial-0001", baudrate=9600) as serial:
    print(["Serial Port Is Open?", "Yes" if serial.is_open() else "No"])

    line = serial.readline()

    print(line.decode("utf-8").strip())

print(["Serial Port Closed"])

The library also provides an asynchronous interface for serial communication, which can be used in an asyncio event loop.

Here's an example of how to use the asynchronous interface:

from samps import SerialAsyncCommonInterface as Serial

async with Serial(port="/dev/tty.usbserial-0001", baudrate=9600) as serial:
    print(["Serial Port Is Open?", "Yes" if serial.is_open() else "No"])

    line = await serial.readline()

    print(line.decode("utf-8").strip())

print(["Serial Port Closed"])
