H3LIS331DL Accelerometer Breakout Hookup
Guide
Introduction
The H3LIS331DL is a high-g accelerometer with I2C and SPI interface
options. It offers an adjustable output range of 100, 200, or 400g, and an
adjustable data rate of up to 1kHz.

Page 3: Hardware Overview
Hardware Overview The H3LIS331DL breakout is fairly simple. H3LIS331DL Sensor IC - This is the sensor IC. Its operating voltage only extends up to 3.6V, so to use it with a 5V Arduino or Arduino clone, you’ll need some kind of voltage translation! It is perfectly centered on the PCB. - Page 4 SparkFun Standard I C Header - Most boards which can be communicated to via I C use this pinout, making it easy to stack them or connect them in a daisy chain.
- Page 5 Page 5 of 12 CS Jumper - Removing the solder from this jumper enables SPI mode. When the part’s CS line is low at boot, it enables SPI mode. SA0 Pin - When the chip is in SPI mode, this goes from being the address select pin to being the MISO pin.

- Converts from raw data to an actual convertToG(maxScale, reading) g-reading. The first parameter is the maximum reading for the current mode, as set by the function. Options are 6/12/24g for the setFullScale() LIS331HH and 100/200/400g for the H3LIS331DL. -

Page 7 of 12 - Set the setHighPassCoeff(high_pass_cutoff_freq_cfg hpcoeff) coefficient for the high pass filter. The actual cutoff frequency is dependent upon the data rate set by . The cutoff frequency is (fs)/(6*Hpc), setODR() where fs is the sampling frequency and Hpc is the high pass coefficient as set by these constants: •... -
Page 8: Example Code
Page 8 of 12 The H3LIS331DL supports I C, SPI, and three-wire SPI data transfer. The library supports I C and SPI mode. Obviously, since SPI requires four wires and I C only requires two, there are different circuit configurations for each mode. - Page 9 Page 9 of 12 S PA R K F U N L I S 3 3 1 A R D U I N O L I B RA RY For the most part, the example code for SPI mode and I C mode is identical.
