python-st3215 1.1.0

A Python library for interfacing with the ST3215 smart servo.

Python-ST3215

Python-ST3215 is a lightweight and intuitive Python library for communicating with ST3215 Smart Servos over a serial bus. It provides a high-level interface for reading and writing servo parameters, controlling motion, and working with the servo memory map.

Features

• Simple API for controlling ST3215 servos
• High-level wrapper for movement and parameter access
• Helpful exceptions for robust applications
• Fully typed and documented through docstrings
• Tested against Waveshare ST3215 hardware

Installation

Install via pip:

pip install python-st3215

Quick Start

from python_st3215 import ST3215, ServoNotRespondingError

controller = ST3215("/dev/ttyUSB0")

try:
    servo = controller.wrap_servo(1)
    print("Current location:", servo.sram.read_current_location())
except ServoNotRespondingError:
    print("Servo not responding")
finally:
    controller.close()

Examples

A collection of example scripts is available in the examples/ directory. These cover tasks such as motion control, serial communication tests, reading/writing parameters, and more.
