Port readings unstable


#1

Hi,

I have some unstable port readings from my digital ports and analog ports.
When reading from them the readings are randomly wrong.
For instance when I read the status from a button, once a while it returns the wrong value.

To solve it I have written a function that reads the port n times and if it is n times the same, the reading is accepted.

However, this is a cumbersome thing to do.
I noticed that was an issue one Month ago concerning sensors and that was solved.

GrovePi Sensors don’t work or analog sensors don’t work [SOLVED]

How can we know that this solution needs to be installed?
Will it also work for my problem?

Kind regards,
Freddy
