Configure gpio as floating input, it will continuously enter the interrupt function

RE: Configure gpio as floating input, it will continuously enter the interrupt function

Hello,

Jonathan is out of office, so I will look into your ticket. Please note that we will all be out of office from tomorrow until April 2nd, so please expect some delay in replies. I am sorry for the inconvenience.

What do you mean? What library do you use to set up your interrupts? Is there an option to set pull? Are you able to set the pull, but you get unexpected results? Or are you not finding where to set the pull configuration at all in that library?

Best regards,

Edvin

Yes, I know this. I tried the nRF5 SDK and it is supported, but I cannot do it in NCS. Can you help me confirm?

Have not tested on this sample but it should work, NO_PULL is supported

Ok,have you tested and verified it on your end?

No pull should be supported for the SoC if that is what you where asking.
