When configuring a pin as a task pin in GPIOTE, is it still possible to use the input buffer?

[David Fernandez]

Hi there,

The PS says that a pin configure as a task will get the output overrided, but does it also get the input overrided?

Hi Hakon,

What I mean by reading the state of a task pin is that:

1. I want the input buffer to be connected to the pin.

2. I want to get the value seen by the input buffer.

Since the task pin will be configured as S0D1 or H0D1, the interesting thing is to read it when the task sets it.

Hi,

 

If I understand correctly, you want to read the input of an GPIO configured as output (overridden by a peripheral). That is not possible. You need to then connect that specific pin to another GPIO (configured as input) to do this.

 

Kind regards,
