#151184 - high/low for before/during touch Responding to: ???'s previous message |
Suresh R said:
Hi all,
I am using capacitor sensing technique for sensing user key press. NE556 was connected in Astable mode and the capsense act as a capacitor in that. Hence the change in output frequency is monitored by a controller for detecting user key press. Suresh. i am also interested in a method where i could make the port logic level high/low for before/during touch. I am yet to get a method to achieve this. can i get a hint on how it need to be approached? Suresh. |
