Hi,

 

MMA8453 is placed inside a device which a person can carry while traveling. We've enabled double tap feature which the person can use in case of emergency. The problem is we're getting false double taps when the vehicle is moving.

Configuration:

REG_PULSE_CFG 0x2A

REG_PULSE_THSX 0x20

REG_PULSE_THSY 0x20

REG_PULSE_THSZ 0x40

REG_PULSE_TMLT 0x18

REG_PULSE_LTCY 0x28

REG_PULSE_WIND 0x3C

Thanks,

Prakash
