Keypad Set bounce and debounce

[TelmoM]

Hi,

I'm having a issue using a long (0.5m to 1m) cable, the values that I get are all mix up!
Is it possible to set the bounce and debounce of the keypad?

Hi @TelmoM,

if you use a shorter cable does it works properly?
Currently the class keypad::matrix doesn't provides functions to set bounce and debounce parameters.
I hope to add them as soon as possible.

Hi @Wicker25,

With a shorter cable the examples work fine. With a long(0.5m to 1m) the example 12keys1 detects always one key-press and multiple key-presses when pressing some keys.
By cutting the cable to 0.2m it started to work fine, I did this experiment several(3x) times and with different cables :)

I can only think that the problem can be solved by changing the bounce/debounce params.

Thanks in advance

Thank you, @TelmoM . I'll try to work on it in the next days.. ;)
Meanwhile, you can try to work around the problem by reading twice the same button.

Thank you very much for the help. I'll try reading twice the same button :)

I just added a function to set the Refresh Rate of the keypad and the support for Event Listener (see the example "keypad/16keys2.cpp").

Try to change the frequency and let me know if the keypad works with a long cable.. :)

p.s. Default frequency is 10 Hz.

Hi @Wicker25
I will try to use a long cable during this week. I'll report the results :)
