TSS library kinetis K20

Hi everyone,


I'm developing a touch keyboard of 12 buttons using kinetis K20.

I developed the TSS driver using processor expert of code warrior 10.2.

Near the keyboard there is a LCD of 7 inches.

The system doesn't work good. When I turn off and turn on it, sometimes the system doesn't read some buttons. I think that sometimes the calibration is different from start to another one.

I tried to solved the problem changing the sensibility of each button, but the system reads buttons different from the pushed one.

Could someone give me some suggest to stabilize the behavior?


Many thanks in advance for your support.


Best Regards,
