Hi~all,
I'm learning cap sense by using CY8CKIT-044 kit. First, I found my SNR test is failed so I would like to re-tune figure capacitance according to user manual. But I can't find figure capacitance item in my tuner software. (Please refer to the attached file 1.)
Could anyone know why ?
Besides, when I found SNR test fail, to adjust figure capacitance to a smaller value is the effective way to let SNR test pass ?!
Do you have any guidance for me to know how to let SNR test pass ?!
Thank you so much.
Solved! Go to Solution.

Hi @Tim_Shih
Are you using CapSense in SmartSense mode or are you using manual tuning? Note that the finger capacitance is available in SmartSense mode only.
In manual tuning, you can increase the resolution of the sensor to increase the sensitivity.
Please note that you need to run the CapSense Tuner in synchronized mode to change the values during run-time.
Best regards,
Hari
