touch issue with STM32f303

[ASaxe]

Hi all,

STM32F303 is as capability to sens touch which is surface touch principal . I am trying to get the values on STM studio but unfortunately i am not able to see any values on it. there always a flat line. I am posting my code can anyone tell me what I am doing wrong.

Because on hardware side these is only 1 register which is on series. apart from that everything is take care by touch library.

any kind of suggestion would be helpful

Thanks in advance
