How does the MCUXpresso IDE add variables to watch in the debug mode run state?

Dear Sir.

How does the MCUXpresso IDE add variables to watch in the debug mode run state??

※Not debug paused add watch

Do you have to use those conditions??

thanks

Although, as Erich says, the standard Eclipse/CDT Expressions view does not support live variables, you can achieve this directly in the Global Variables view. As well as supporting the addition of Variables (using the "spectacles" icon), the Global Variables view also provides an "Add new expression" option (inside the view itself, rather than in the view's icons).

In the below screenshot (debugging the K64/Bubble example), I am displaying the global "g_xAngle" as a variable, and also have added it as an expression too :

I hope this helps,

Dear Erich Styger,

Thank you for your reply, "Global Variables" window I have tried this function. Because of this function, the IDE will crash for a while, so I would like to ask if I have used Add Watch Expression and then observe it in Expression.
※ Hope is in the debug mode run mode Add Watch Expression

The expressions view does not support the live variable function. You have to use the variables view for this. If you want to monitor an expression, you would have to calculate that expression in your code and store it in a global variable instead.

Which IDE version and what debug connection are you using? Note that there has been an identified issue with P&E/SEGGER using live variables in IDE 11.0.0 which causes some unintended side effects. The LinkServer connection is not affected by that.

Dear Erich Styger,

I am using MCUXpresso IDE v11.0.0_2516, then I am using the P&E driver on NXP EVB to burn/debug, I will try to see what you said CMSIS drive to do this, but currently I use MCUXpresso IDE v11.0.0_2516 through CMSIS Driver also has a very unstable situation, I plan to use lpc-link2 to try again.

Thanks a lot...
