FreeMASTER is a user-friendly real-time debug monitor and data visualization tool that enables runtime configuration and tuning of embedded software applications. Both automotive OEMs and
industry-leading appliance manufacturers widely adopted FreeMASTER as it is suitable for use in a broad range of automotive and industrial applications.
FreeMASTER supports non-intrusive monitoring of variables on a running system and can display multiple variables on oscilloscope-like displays as standard widgets (gauges, sliders and more) or as
data in text form, offering simple-to-use data recorders.
FreeMASTER can link with custom HTML, MATLAB® or Excel to other scriptable frameworks to add MCU hardware into control loops. Connection to the target system from a host running FreeMASTER may be
made directly over a broad range of communication peripherals or debug channels. FreeMASTER embeds graphs, tabular grids and web views directly in the desktop application. FreeMASTER connections
are made via a network connection using JSON RPC calls, with client implementations available for Python, C/C++/C# and other languages.
FreeMASTER offers a new component: FreeMASTER Lite. It is a lightweight service leveraging the JSON RPC protocol that can run on Windows or Linux host PC and enables the implementation of custom UI
applications on a web browser application (running on a local or remote host computer or mobile device).
FreeMASTER 3.1 extends the FreeMASTER Lite by supporting the Node-RED framework. Node-RED enables
the visual programming of event-driven applications. FreeMASTER 3.1 brings a palette of Node-RED "nodes" that act as visual wrappers around JSON-RPC calls, leveraging the full potential of both
FreeMASTER and Node-RED to design visual dashboards with minimal or no coding at all.
