Error while trying to turn on NRF52DK using NPM1300 GPOIs

[Pallavi_03]

Hi,

We're currently working on a project that involves using the NPM1300 to power the NRF52 DK using the GPIO pins. We've managed to supply 3.3V using the GPIO button but encountered an issue where the voltage drops to 0V as soon as the button is released.

Additionally, we attempted to utilize the one-button example provided in the documentation, but we didn't observe significant changes in the voltage behavior. Furthermore, when trying the NPM1300 one-button example, we encountered an error stating "led driver not found."

Any insights on potential hardware configurations or where we might be going wrong would be greatly appreciated.

Thanks and regards

Hello, 

Can you provide more information on your setup? How have you connected? And how are you measuring? 

Additionally, we attempted to utilize the one-button example provided in the documentation, but we didn't observe significant changes in the voltage behavior. Furthermore, when trying the NPM1300 one-button example, we encountered an error stating "led driver not found."

I'm not able to reproduce, though I tested with the first kit at hand i.e. nRF9160DK.

Thanks. 

Kind regards,
Øyvind

hello!
We have followed the exact connections as mentioned in the documentation.

Thanks and regards.

Understood. 

We've managed to supply 3.3V using the GPIO button but encountered an issue where the voltage drops to 0V as soon as the button is released.

Where did you measure this? 

we encountered an error stating "led driver not found."

Could you provide a build log where you get this error?

Hello!
We managed to get the "one button" example in the documentation to work. 
The current issue we're facing is that when the ship mode is released, there doesn't seem to be a event callback.

And could you also let us know how to clear the interrupt using I2C?

Thank you!

Sorry for the late reply. 

Have a look at the nPM1300 Event and interrupt registers in the PS.
