SparkSerial Pro
A lightweight Serial GUI Tool for hardware testing and debugging built with Python and PyQt6. Inspired by professional tools like Docklight and CoolTerm, SparkSerial provides a modern, user-friendly interface for engineers and developers.
⚠️ Important: USB Driver Requirement
SparkSerial is a GUI application only. It does not include USB-to-Serial drivers. You must install the appropriate driver for your USB-to-Serial adapter/converter separately.
Common Drivers:
- FTDI chips (FT232, FT2232): FTDI Drivers
- CH340/CH341: CH340 Driver
- CP210x (Silicon Labs): CP210x Drivers
- PL2303 (Prolific): PL2303 Driver
After installing the driver, your serial port should appear in the Port dropdown.
Features
- Professional Configuration: Comprehensive port settings (Baudrate up to 921600, Data Bits, Parity, Stop Bits, Flow Control, Line Ending).
- Command Shortcuts: Save frequently used commands (Text or Hex) for quick access and batch testing.
- Find/Replace: Bulk find and replace text across all saved commands.
- Command History: Use ↑/↓ arrow keys to navigate through previously sent commands.
- Advanced Terminal: Real-time logging with timestamps, Hex view, and autoscroll.
- Persistence: Automatically saves your command library.
- Base Converter: Built-in tool to convert between Decimal, Hex, Binary, and ASCII instantly.
- Modern UI: Industry-standard dark-mode aesthetic optimized for hardware debugging.
- Cross-Platform: Designed for macOS, Windows, and Linux.
