USART HMI 3.1

USART HMI is a human–machine interface and serial monitor designed for devices that communicate over UART/USART. It lets you connect to a serial port, visualize data in real time, send commands, and build simple control panels—streamlining everything from prototyping to production testing.

Key features

• Fast serial connection: Configure baud rate, parity, data/stop bits, and flow control.
• Clear data views: Switch between ASCII and HEX, add timestamps, choose line endings, and filter or search streams.
• Command automation: Create macro buttons, reusable command templates, and send sequences with adjustable delays.
• Logging and export: Record sessions and export data to CSV or JSON for analysis and reporting.
• Real-time visualization: Plot values on live charts and use gauges, sliders, and toggles to interact with your device.
• Packet helpers: Define message framing and apply common checksums to validate data integrity.
• Multi-session workflow: Work with multiple devices or ports in parallel using tabs and saved profiles.
• Customizable layout: Arrange panels to fit your workflow, with optional light and dark themes.

Typical use cases

• Debugging microcontrollers, sensors, and embedded systems
• Tuning device parameters and issuing firmware commands
• End-of-line and field testing with repeatable command sets
• Teaching and demonstrations of serial communication

USART HMI helps engineers, technicians, and hobbyists turn raw serial data into actionable insight—without extra firmware changes or custom PC tools.

USART HMI is developed by TJC. The most popular version of this product among our users is 2.0. The name of the program executable file is USART HMI.exe.
