Hi,
I'm using cdt to develop an embedded application based on IAR. For testing purposes we are porting the application to mingw to create an emulator. Everything is working fine but I'm missing a lot a livewatch window to see variables value while the application is running without pausing it. Is it possible? I checked online but I was not able to find anything about that.
I tried last CDT 2021-09.
thanks for the support, I hope it's not a double post.
Michele

What you seem to asking for is a live telemetry stream.

The closest thing would be a hardware watchpoint.
These are available through GDB but they are effectively breakpoints
that trigger when the value changes and are available only on some
cpus. The program stops when triggered. You set them by right clicking
on a variable in the Outline View.

CDT (through GDB) provides a dynamic printf that prints values
at a breakpoint then automatically resumes execution. I think the
program is paused while printing.

You can also cause a breakpoint to execute certain actions when encountered.
Right click on a breakpoint in the program and view the breakpoint properties
to see what's available. Documentation is sparse.

Thank you David for your answer. Effectively a real debugger just constantly access processor memory while it executes and sends out the requested data: compared to a printf the difference is that data is just shown and through away while in printf there is a lot of prints and the console is filled and it' not possibile to add variables while application runs.
thanks
