Quick Start

Get up and running in minutes with our simple installation and basic example.

Installation

1

Install Python Library

Install the ESP32 GPIO Bridge library via pip.

2

Flash ESP32 Firmware

Upload the modular firmware to your ESP32 board.

3

Start Controlling Hardware

Connect and control GPIO pins from Python.

Basic Example
from esp32_gpio_bridge import ESP32GPIO, find_esp32_port

# Auto-detect ESP32 port
port = find_esp32_port()

# Connect using context manager
with ESP32GPIO(port) as esp:
    print(f"Firmware version: {esp.get_version()}")
    
    # Digital output - LED control
    esp.set_pin_mode(2, "OUT")
    esp.digital_write(2, 1)  # LED ON
    
    # Analog input - Sensor reading
    sensor_value = esp.analog_read(34)
    voltage = (sensor_value / 4095.0) * 3.3
    print(f"Sensor voltage: {voltage:.2f}V")

Ready to Get Started?

Transform your ESP32 into a powerful hardware interface with professional-grade Python control.

What's New in v0.1.8-beta

All critical issues resolved! The ESP32 GPIO Bridge is now production-ready with zero known issues.

No More Reboots

Fixed hardware watchdog timer issues that were causing unwanted ESP32 restarts during normal operations.

Stable Communication

Enhanced serial communication with robust error filtering and mixed message parsing. No more parsing errors!

No More Hangs

Fixed ESP32 hang issues after idle periods by optimizing failsafe mechanism and health monitoring.

Optimized Performance

Less aggressive failsafe timeouts (30s vs 10s) and simplified health monitoring for better responsiveness.

Reliable Operation

100% test success rate with zero reboots, zero parsing errors, and stable long-term operation.

Production Ready

Comprehensive testing confirms the ESP32 GPIO Bridge is ready for production use with all core features working perfectly.
