Hi,

You need to provide more details on your issue to get any help.

What are you using GPIOTE for? How do you interface the chip? What do you mean by "gpiote is not working continously"?

Please post the code you are using, and describe the behavior and problem in details.

Best regards,
Jørgen

Hav u gone through mt code?

[Jørgen Holmefjord]

I have looked at it, but I can't see any obvious reasons for this behavior. Can you post the full project for us to reproduce the behavior?

This is the full code..i have included ble for later use..ignore it..gpiote is not working and i cant figure it out..what are the sdk configurations for gpiote..

[Jørgen Holmefjord]

I can see that it is the full code from main, but if I add that into an existing project, I would most likely need to add a lot of source files/header file paths in order to even compile your code. If you can upload the full project directory with project files (SES, Keil, etc), that will save a lot of time to debug the issue.

Okay..surely i will uploadit tomorrow..i hav checked and seems to find out that it is the problem with lead off and lead on condition i hav written and also the pll is not working correctly..

how do i upload full code?its showing error when i copy paste full folder.

[Jørgen Holmefjord]

You should put it in a zip file first. You do not need to upload the entire SDK directory, only the project folder.

Hav u looked at it?

I tested your application, but I had to change the GPIOTE pin to another one (P0.11), as P0.17 is used for QSPI flash chip on the nRF52840 DK. I can't see any issues with GPIOTE.

Did you test this on a custom board, or on a nRF52840 DK? Can you describe the issue in more detail?
