You would likely get a merge conflict that you then need to resolve. git has the functionality to help you handle that.

If you have made changes you think other Zephyr users might find useful, please feel free to submit a patch to upstream Zephyr. See this link.

I'm not sure how I would do that. If I did do something like this, since I would be changing the driver code wouldn't it get overwritten when I do an NCS update?

I did implement a flag and a test in the trigger handler itself. I flip the flag back and forth as if I am disabling it. Not power efficient but it works. At some point Ill test how much more power the Accel motion trigger draws. If you know how much that might be It would save me some time and Id appreciate it. If you don't know but you'd like to know I can provide the code I have for power testing.

Hi,

The sensor API in Zephyr does not seem to have this disable functionality implemented. Maybe you could try to implement a function in adxl362_trigger.c or adxl362.c that e.g. write to the INTMAP1 register in order to disable the interrupt ?
