Switch Debounce Protection built in?

sciguy

Does the Basic Stamp 2PE support switch debounce protection built in to the hardware? Or does it have to be accommodated for in the code?

Thanks

Hello,

That depends…If you’re using the BUTTON command for a single input you can handle debounce through the command. If you’re trying to read the switches some other way you will need to handle debounce. This has been covered in the Stamp Works Manual if you would like an example of debouncing multiple switches. Take care.

I don't quite understand... I'm using a Vibration sensor, and It is either activated or not. However, I've amplified the signal, and I want to make sure it doesn't jump between rails and get the stamp confused. The amplification adds some noise.

Here is the code:

' {$STAMP BS2pe}
' {$PBASIC 2.5}

VibrationPin    PIN     15
VibrationLEDPin PIN     11

Slip:
LOW VibrationLEDPin
IF VibrationPin=0 THEN Slip
HIGH VibrationLEDPin
GOTO Slip

There’s no confusion…As soon as it’s detected you can take action…There’s no need to debounce a vibration sensor. Just wait for the active state and jump to your handling routine. Take care.
