XIAO BLE Sense (nRF52840) Absolute Wrist TIlt

[PJ_Glasso]

Hi there,
So I hear you on the INT2 thing. I know the schematic.
but check this out… You can map everything to INT1 pin, small amount of code overhead but can do.
Check out this thread, from Honvi a while back. Dude was like a hound dog on the hunt.
turns out same is for the LSM6DS3 part.
Register writes are all that’s required to configure. YMMV

XIAO BLE Sense - LSM6DS3 INT1 Single Tap Interrupt

I may be wrong about the absolute wrist tilt function not being usable. I found a register that reroutes INT2 interrupts to the INT1 pad. CTRL4_C (13h) INT2_on_INT1 All interrupt signals available on INT1 pad enable. Default value: 0 (0: interrupt signals divided between INT1 and INT2 pads; 1: all interrupt signals in logic or on INT1 pad) Here is a schematic from another STM accelerometer that roughly shows how it works: [image]

continue…
