# samps
A hypermodern, type-safe, zero-dependency Python library for serial port I/O access.
## Installation
```bash
pip install samps
```
or
using your preferred environment / package manager of choice, e.g., `poetry`, `conda` or `uv`:
```bash
poetry add samps
```
```bash
conda install samps
```
```bash
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:
```python
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:
```python
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:
```python
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"])
```
