Title: De-Bouncing
Post by: dan on June 14, 2007, 08:10:51 AM

Hi,

What will be the best way to de-bouncing 9 inputs on the T100.
I would like to do this thru programing and if is possible to be able to adjust it.

Thank you,

Dan

You can connect each input to one timer with say a 0.2s time-out. The timer contact will be the one that is actually used to trigger a process. As long as the input is bouncing with cycle time of less than 0.2s, the timer will be reset repeatedly. Only when the bouncing stop then the timer has a chance to time out and the its contact become a debounced input to the program.
