Hi,Community,

I'm looking for a software processing method to get more accurate capsense values, excluding noise and parasitic capacitance.

I guess it can be realized by active shielding or passive shielding method with reference to 3.4.6 CAPSENSE CSDRM shierlding in AN85951 in terms of hardware.

If the active shielding or passive shielding method is to be implemented in software, could you please let me know if there is any sample code available?

The feature I would like to use is the CSD-RM mode of the capsense buttons.

And the PSoC4 MCU I am using, capsense is supported by the 5th generation.

Hi @NXTY_Tatebayasi -San,

 

Please refer to https://www.infineon.com/dgdl/Infineon-ModusToolbox_CAPSENSE_Configurator_5.0_User_Guide-UserManual-... Page 23 to 25. Here you can enable shield and Select which shield you want to choose. Then please go ahead and assign pins which should be driven to shield and you're good to go.

Thanks!
Kind Regards
