How to find out what frequency PSoC LP5 is running at?

[yaga_3967241]

Like the CPU frequency for a CPU, how to find out at what frequency the PSoC is running?

Regards,

yaga,

Do you have the Creator project file for this running PSoC?

Yes.

Hi,

In your  Workspace Explorer > <your project> > Design Wide Resources 

Double click "Clocks"

DWR Clocks will be shown.

You can tell the frequency even here, but to see graphically,

double click somewhere in the "Source Clock" area.

Configure System Clocks window will be shown.

Probably the "speed" you asked is either "MASTER_CLK" or "BUS_CLK".

And needless to say you have control over how to configure these values in this window, too.

yaga,

Actual processor frequency may vary from the one listed in the System Clocks Config by few %%. It also changes with temperature if not locked to a XTAL. If precise frequency is needed, you can measure it directly using a o-scope or frequency meter by connecting a BUS_CLK clock to a digital output pin.
