LIS3DH Interrupt line

Hi,

Is it possible to disable the interrupt line? By default it is Default: push-pull output forced to GND but I would like to be able to make it floating to use the ucontroller gpio connected to INT1 for other purposes like UART TX.

Thank you

Hi @josescxavier​ , do you mean change the INT1 internal config from push-pull to open-drain? Unfortunately is not possible... please note that even if the pull down to gnd is very weak, the use of INT1 pin routed to UART com could cause a little x-talk. Better to leave it unconnected, even if I suspect it would require a HW rework. Regards
