Leo Bodnar BBI-12 Rotary Debouncing

[Enabler]

I am experimenting with the Leo Bodnar BBI-32 and the BBI-12 rotary switches. 

I love that the rotary is capable with 2 wires. It is connected through the BBI-32 board. Which is awesome as there is no coding needed. However there is a problem. The rotary works. BUT it bounces. This is very bad especially on the Viper INS switch. 

Is there a way to debounce this switch since there is no coding through this board?

Do you have any small capacitors?  Could try putting one across the two pins.
Also, email the company.  They might have some ideas.

Like No1sonuk said above, caps are a good idea.

If you want another potential alternative, reducing the polling frequency of the switch (in software or physically if there is a clock somewhere) is a crude but simple fix in my experience. Perhaps you could check if there is a way to change the polling frequency of the usb device in your OS.

I have been in contact with Bodnar about this. I demonstrated the bounce to them and they said it shouldn’t happen. They modded a few of these for me to test but haven’t arrived you. We’ll see…

I contacted them and they have been extremely helpful. They sent me 4 switches to test that were modified with capacitors. They work great now.

Can you describe or provide photo of how the caps are placed, and cap size?

I don't know the size but they are smd and bridge the gap between the pos and neg pads.
