Plot serial data in realtime with sample time of 1ms

Hello,

My MCU is sending data with sample rate of 1000 samples/sec via serial port. how can i visualize this data in realtime on scope? please find attached simulnik model snapshot.

Regards,

You can easily log signal and check the signal from Simulink Data Inspector :

API : https://www.mathworks.com/help/slrealtime/ug/inspect-signals-in-external-mode-using-simulation-data-inspector.html

But I think 1kHz is too high for data visualization,

1. Use rate transition blk. to reduce sampling rate.
2. Attach File Log blk. at the signal for the full data(if necessary, this will log data at the target machine, and after simulation ends, all the data will be transferred through TCP/IP).

If each data point were allocated 1 pixel, then 1 kHz would fill the width in 1 to 2 seconds.
