Hello,

   

I have attached the snap shot, which explains where to set sense and modulator clock divider value. Kindly refer the attachment. Double click the CSD component, go to "scan order" tab, you may find the sense and modulator clock divider value. 

   

To measure the absolute capacitance of Capsense pin, CapSense_GetSensorCp() API is used. 

   

Thanks

Hello Ramesh,

   

  Thanks for your prompt reply. Sorry for that I didn't speak clear question. I knew how to setup the scan speed.

   

After I use CapSense_GetSensorCp() API to get the value of capacitive sensor, how to decide the scan speed.

   

In CSD datasheet, the Cp of sensor is a scope from 10pF to 50pF.  For higher Cp, do we setup the low scan speed to keep the

   

integrity of charge and discharge? I can observe the wave by oscilloscope.  Do you have a table to show this?
