Feetech STS3215 Servo Monitor and Visualizer

A Python tool for real-time monitoring and visualization of Feetech STS3215 servo parameters (position, speed, load, voltage, temperature) over a serial connection.

Features

• Real-time plots for position, speed, voltage, and temperature for up to 6 servos
• Color-coded lines for each servo
• Rolling 10-second window for live data
• Pause/resume live update with the spacebar
• Robust to communication errors and missing data
• Debug output for troubleshooting

Requirements

• Python 3.7+
• Feetech STS3215 servos (or compatible)
• USB-to-serial adapter

Installation

1. Clone this repository or copy the files to your machine.
2. Install dependencies:

   pip install -r requirements.txt

Usage

1. Connect your servos to your computer via a USB-to-serial adapter.

2. Run the monitor:

   python read.py --port COM5

   Replace COM5 with your serial port (e.g., /dev/ttyUSB0 on Linux).

3. Optional arguments:

   • --baudrate 1000000 (default: 1000000)
   • --ids 1 2 3 (specify servo IDs)
   • --debug (enable debug output)

Troubleshooting

• If only position updates, check your servo model and wiring.
• If speed/load/voltage/temperature are always zero, check the register map and power supply.
• Use --debug to see raw communication data.
• If you get shape mismatch errors in the plot, update to the latest code.
