schmitt triggers on nRF51 GPIO

[Bryan Hood]

Could someone confirm whether there are schmitt triggers on the nRF51822 GPIO. I found the following thread that mentions them, but it also is discussing the nRF52 series so I was not sure. devzone.nordicsemi.com/.../

Thanks!

Hi Bryan,

I am pretty sure that the GPIO peripheral on the nRF52 is close to, if not identical to that of the nRF52. However, I will update my answer as soon as I get this confirmed.

Edit: 25.07.17

Like the nRF51, the GPIO peripheral on the nRF52 uses Schmitt-Triggers.

Best regards

Was this ever resolved, Re are the inputs to the nRF51 devices indeed Schmidt-triggers? There's a whole lot of hysteresis, which implies they are... but I'd like to verify.

Thanks for the update!
