Current statusPaused development for now, will restart once I find better ways of managing and distributing general-purpose embedded libraries. However, library is functional good stability & test coverage.

Telemetry enables easy communication and data visualization between a computer and any embedded platform, likeARM Mbed orArduino.

Specifically,Telemetry is a communication protocol, implemented in C language.

Data is exchanged on named channels, calledtopics (ex :foo,bar andqux on the figure above).

Sending data is calledpublishing.

Telemetry TM;int32_t i =123;TM.pub_i32("foo", i);

For receiving data,Telemetry lets you attach variables and functions to topics.When fresh data is received under a topic, attached variables will be updated and attached functions will be called.

Telemetry TM;float thr;TM.attach_f32_to("throttle", &thr);for(;;) {  TM.update();}

Telemetry is written to be portable and general-purpose, and the core code is not tied to any hardware.

Wrappers for specific platforms are written to provide a plug-and-play manner to use Telemetry:

• Arduino wrapper
• Mbed wrapper (Available also onMbed repository )
• Yotta (package manager) - in process

As soon as a device publishes data, it is possible to leverage the power ofthePytelemetry Command Line Interface.

This terminal application lets you interact with the device, using simple commands.

Opening a live plot is as simple as
