Telemetry Viewer is a data visualization tool designed for working with live or recorded telemetry data. It can visualize data received over UART, TCP, UDP, or camera connections, making it useful for embedded development, hardware testing, robotics, sensors, and other projects where real-time data needs to be inspected graphically.
This is free and open source software.
Key Features
- Visualizes telemetry received over UART, TCP, UDP, or camera connections.
- Provides a data structure screen for defining how incoming UART, TCP, or UDP data is laid out.
- Supports multiple telemetry streams in a single session.
- Lets users create and configure charts in a tiled workspace.
- Offers controls for rewinding, fast-forwarding, zooming, and adjusting display scaling.
- Imports previously saved settings, CSV telemetry data, and MKV camera files.
- Exports settings, acquired samples, timestamps, and camera data.
- Can automatically load a default settings file at startup.
- Supports drag and drop importing of saved Telemetry Viewer files.
- Cross-platform support – runs in Linux and Windows.
