Debouncer on Digilent myDigital Protoboard

[Samuel Ulehla]

HI.

Is there any debouncer integrated for push buttons or switches for this board? If not, how should I make one? One pin on the push button is connected to +5V through a 200ohm series resistor, and the other is probably output.

Hi @Samuel Ulehla,

There is no debouncer integrated for the push buttons or switches on the MyDigital Protoboard. The outputs have both a 2.2k ohm pulldown resistor and a 200 Ohm series resistor to the output signals, with the 5 V rail being 'visible' once the button is depressed. Regrettably I don't have permission to simply share the schematic of this particular module.

As for implementing debouncing, you can either do it through external capacitor or through software debouncing. Depending on how the digital inputs of the attached controller board detect high and low signals, particularly at 5 V logic, I'd likely be more inclined to do it in software.

Let me know if you have any questions.

Thanks,
JColvin
