Hi,
We are doing manual tuning of CapSense.
First, we decided the resolution from the SN ratio.
We understand that "IDAC" and "Analog switch divider" are items like fine adjustment.
There are threshold values that stop working at all by changing the numerical values of "IDAC" and "Analog switch divider".
For example,
Set Analog Switch Divider to 3: Works fine
Set Analog Switch Divider to 2: No response
in this case,
Analog switch divider will be better not to set to 3?
Is there a document on manual setting of "IDAC" and "Analog switch divider"?
Descriptions of the function are described in the data sheet, but there is no description of how to set it to the optimum value manually.
Solved! Go to Solution.

Hi Masashi-san,
Could you please refer to the manual tuning section of the PSoC 5 LP CapSense design guide? (https://www.cypress.com/documentation/application-notes/an75400-psoc-3-and-psoc-5lp-capsense-design-...)
You could use SmartSense auto-tune initially to know the range of IDAC values set and change them according to your requirements, in manual tuning mode, by following the manual tuning process explained in the application note.
Thanks,
Shanmathi

Shanmathi-san,
I never changed Analog Swich Divider, but I read and understood the application notes.
Thank you.
