Abstract FreeMASTER-Sensor-Tool v1.0 Release Notes
NXP Semiconductors
1 Overview
FreeMASTER sensor tool is an evaluation and application development software based
on the NXP FreeMASTER framework for IoT/Industrial/Medical sensors.
The FreeMASTER sensor tool provides ease of use through common development
platform integration. This tool utilizes the FreeMASTER tool framework for GUI
development, and integrates with MCUXpresso SDK and ISSDK for embedded
application development.
FreeMASTER sensor tool provides a quick out-of-box sensor demonstration and
flexibility for end users to rapidly prototype customized GUIs.
2 Features
2.1 Supported features:
• Real-time sensor output monitoring: Supports multiple memory variable monitoring
at individual sampling rates and for up to eight streams in the oscilloscope/graph view.
• Real-time sensor register control: Supports modification of memory variables and
registers in real-time. Control/configure sensor device in real-time with register write
capabilities.
• Data visualization: Enables third-party instrumentation components inserted into the
HTML code as embedded objects. Allows for the creation of user-friendly displays of
complex, real-time data dashboards.
• Sensor register page: Provides a register map of the sensors and allows quick read
and write of different register bit-fields in real-time, allowing detailed sensor evaluation.
• Out of the box sensor demonstration: Provides quick visualization of sensor data
and other sensor outputs based on the pre-configured sensor settings in the firmware.
• Development Platform Integration:
– Integration with MCUXpresso SDK using ISSDK and FreeMASTER drivers for
– Integration with FreeMASTER v 3.x with flexibility to extend JavaScript-powered

4 Known issues
• Packet losses: Higher output data rates (>400 Hz) for output watch variables cause
packet losses as a result of throughput limitations on OpenSDA.
• Control page update: The FreeMASTER classic framework makes a web socket
connection to localhost: 41000 to talk to HTML control page implementation. Based
on Windows PC performance, the server may start a bit slower. The slower start inturn delays the control page update. If this occurs, reload the control page by pressing
refresh button or F5 key after a few seconds.
