setHighPassCoeff(high_pass_cutoff_freq_cfg hpcoeff) - Set the
coefficient for the high pass filter. The actual cutoff frequency is dependent
upon the data rate set by setODR() . The cutoff frequency is (fs)/(6*Hpc),
where fs is the sampling frequency and Hpc is the high pass coefficient as
set by these constants:
•LIS331::HPC_8 - Sets coefficient to 8.
•LIS331::HPC_16 - Sets coefficient to 16.
•LIS331::HPC_32 - Sets coefficient to 32.
•LIS331::HPC_64 - Sets coefficient to 64.
enableHPF(bool enable) -true to enable, false to disable.
HPFOOnIntPin(bool enable, intSource) - Does the high pass filter apply
to the signal the interrupt is based on? true to enable, false to disable,
and the second parameter is 1 or 2 depending on which interrupt you wish
to apply this setting to.
intActiveHigh(bool enable) -Pass true to set the interrupt pin to active
high, false to set it as active low. Default value is active high.
intPinMode(pp_od _pinMode) - Are the interrupt pins open-drain or push
pull? Pass LIS331::PUSH_PULL or LIS331::OPEN_DRAIN .
intSrcConfig(int_sig_src src, pin) - What sort of thing triggers an
interrupt, and which pin shows the interrupt. The options are:
•LIS331::INT_SRC - Interrupt source is the same as the pin number.
•LIS331::INT1_2_SRC - Either interrupt will be reflected on the pin.
•LIS331::DRDY - The “new data ready” signal will be reflected on the
pin.
•LIS331::BOOT - The boot mode status of the part is reflected on the
pin.
setFullScale(fs_range range) - Sets the range of the part, as listed
below:
•LOW_RANGE - +/-6g for the LIS331HH or +/-100g for the H3LIS331DH.
•MED_RANGE - +/-12g for the LIS331HH or +/-200g for the
H3LIS331DH.
•HIGH_RANGE - +/-24g for the LIS331HH or +/-400g for the
H3LIS331DH.
bool newXData() - returns true if new X data is available since last read
of X data register.
bool newYData() - same as newXData() for Y axis.
bool newZData() - same as newZData() for Z axis.
enableInterrupt(int_axis axis, trig_on_level trigLevel, interrupt, bool enable)
- axis can be LIS331::X_AXIS , LIS331::Y_AXIS , or LIS331::Z_AXIS .
trigLevel can be LIS331::TRIG_ON_HIGH or LIS331::TRIG_ON_LOW ,
interrupt can be 1 or 2, and enable is true to enable the interrupt and
false to disable it.
setIntDuration(duration, intSource) -duration can be any value from
0-127, and represents the time in number of samples that the sensor must
read above or below the threshold set by the user. intSource is 1 or 2.
setIntThreshold(threshold, intSource) -threshold is the absolute
magnitude above or below which an interrupt will occur, divided by 16. It
can range from 0-127. intSource is 1 or 2.
