change live expression Update rate in IDE

[VidhiPa]

The STMcube IDE1.18.0  updates live expression very fast. How can I reduce the update rate, if possible?

How to accurately read ADC value for sensor calibration in this case ?

That's the whole idea of live expression. It updates live.

1. Print the values to a UART peripheral.
2. You can pause debugging to view the value
3. Slow down you ADC conversion so live view is updated at a slower rate.

Yes, of course I understand that. I use workarounds like UART, but older version of STMCube IDE has it updated slowly than this version, so I wanted to know if there is a way to modify this.

In this application, I wouldn't call a UART (or similar) a "workaround" - I'd say it's a more appropriate approach to the problem.

Hello @VidhiPa 

In addition to the suggestion of @Karl Yamashita, you can also Set breakpoints at points of interest and inspect variables when halted.

That's a separate question!

For this, I'd use output to a UART (or similar) as @Karl Yamashita suggested.
