MiniProfiler/host

MiniProfiler Host Application

Python-based host application for real-time embedded profiling visualization.

Quick Start with uv

1. Setup

# Create virtual environment
uv venv

# Activate it
source .venv/bin/activate  # Linux/macOS
# or
.venv\Scripts\activate     # Windows

# Install package
uv pip install -e .

2. Run

# Start the web server
miniprofiler

# Or with options
miniprofiler --host 0.0.0.0 --port 8080 --verbose

3. Test with Sample Data

cd tests
python sample_data_generator.py

Open http://localhost:5000 in your browser.

Using the Makefile

From the project root:

make install    # Install with uv
make run        # Run the server
make sample     # Generate sample data
make clean      # Clean build artifacts

Requirements

• Python 3.8+
• uv (recommended) or pip
• Serial port access for real hardware

Features

✅ Binary protocol with command-response structure ✅ Real-time serial communication ✅ ELF/DWARF symbol resolution ✅ Three visualization modes:

• Flame graph (d3-flame-graph)
• Timeline/flame chart (Plotly.js)
• Statistics table ✅ WebSocket-based real-time updates ✅ Sample data generator for testing

Next Steps

1. Connect to STM32 device (Phase 2 - embedded module TBD)
2. Load .elf file for symbol resolution
3. Start profiling and view real-time visualizations
