Part Number: MSP430FR2633
Hello ,
I am using MSP430FR266 for our capacitive touch keypad application which has 16 touch button using mutual capacitance. Currently , it works perfectly fine when the user touches keys softly, but whenever the touch is hard just like one presses the physical button, touch is not detected and it hangs for few seconds. I am attaching my captouch config file.
Please let me know if more information is required for this purpose.
