Hi,

Can I use FreeMaster to monitor FlexRay Transmitted frames from a node ?

If yes which document i can refer to use FreeMaster.

Hi Deepak‌,

FreeMASTER won't help much with such tasks as communication bus analysis/sniffing. It's main purpose is to monitor and control your embedded application variables. You could still be able to get some data going through FlexRay by copying the frames into a variable and display it in FreeMASTER UI, but that does not guarantee you the same accuracy as a dedicated analyser, because FreeMASTER may not read data from the target at the same rate, at which dataframes come from FlexRay.

An example of a task that would be a better fit for FreeMASTER is to monitor communication statistics (ex: number of frames send/received), but it would still require a piece a piece of logic, that gathers those statistics and stores them, implemented in the embedded application.

Regards,

Iulian

Hi Iulian,

Can I use FreeMaster as like oscilloscope to monitor the flexray tx and rx frames signals. If yes then, it is possible to decode the signals.

No, FreeMASTER cannot monitor raw signals.

Short clarification: FreeMASTER has a functionality called "oscilloscope" (to not be confused with signal processing device). It provides the capability to plot one or multiple embedded application variables on a chart widget similar to how signal data is visualized on an actual oscilloscope display.
