Hello,
I am using the Bosch API that I modified to work with the nRF52832 and the Grove Step Counter Grove - Step Counter(BMA456) | Seeed Studio Wiki.
I am attempting to see the step counter output or if the interrupt triggers but it seems it doesn't as when reading either register they are always 0.
I would love to hear any ideas of how to modify my code or even if you think perhaps the Grove step counter may be to blame. Thank you for any help.
Here is the output on Putty:
