Simulink Real-Time went through a major product update for the R2020b release. Graphics support has been removed as part of this in favor of a more performant SSH shell-based BlackBerry® QNX Neutrino® real-time operating system. This means that it is no longer possible to visualize signals on the target screen. Instead, a text-based status monitor is visible on the target screen:
You can use the methods outlined in the following MATLAB Answer to visualize live data from your real-time application on a connected host computer:
The simplest approach is to mark your signals for logging, which enables live streaming to the Simulation Data Inspector (SDI) in MATLAB. See:
If your Speedgoat is running in standalone mode and connecting a host computer is not an option, you can consider printing messages to the system log within the status monitor, as demonstrated in the following documentation example:
