Hi,

I'm using ADXL362 in my application. I want to use the triggered mode on activity interrupt. If i well understood, the fifo will fill up, everytime when there is activity. But even there is no activity, my fifo filled up until it is full. (just like stream mode)

I configured my sensor like this.

 

adxl362_write_register(ADXL362_THRESH_ACT_H, 0x00));

adxl362_write_register(ADXL362_THRESH_ACT_L, 0xFA));

adxl362_write_register(ADXL362_TIME_ACT, 0x02));

adxl362_write_register(ADXL362_THRESH_INACT_L, 0xFF));

adxl362_write_register(ADXL362_THRESH_INACT_H, 0xFF));

adxl362_write_register(ADXL362_TIME_INACT_L, 0x20));

adxl362_write_register(ADXL362_TIME_INACT_H, 0x00));

adxl362_write_register(ADXL362_ACT_INACT_CTL, 0x3F));

adxl362_write_register(ADXL362_INTMAP1, 0x00));

adxl362_write_register(ADXL362_INTMAP2, 0x00));

adxl362_write_register(ADXL362_FILTER_CTL,0x12));

adxl362_write_register(ADXL362_FIFO_CONTROL,0x03));

adxl362_write_register(ADXL362_FIFO_SAMPLES,0x86));

adxl362_write_register(ADXL362_POWER_CTL, 0x0B));

   

Thanks
