Hi Julien,
Sorry for the delay.
"int_thresh_var_en" corresponds to APDS9306_INT_CFG_REG bit 3 (Datasheet: INT_CFG, Address: 0x19) which
is a single bit value only. If user does "echo 4 > /sys/bus/iio/devices/iio:device0/events/thresh_adaptive_either_en",
which trickles down to the "state" variable, do we really want to write any other value except "0" or "1"?
Correct me if I am wrong here.
