Micropython LISD3H library¶

`lis3dh`¶

LIS3DH MicroPython Driver

Author(s): Jose D. Montoya

class micropython_lis3dh.lis3dh.LIS3DH(i2c, address=0x18)[source]¶

Main class for the Sensor

Parameters:¶

i2c : I2C¶: The I2C bus the LIS3DH is connected to.
address : int¶: The I2C device address. Defaults to 0x18

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the lis3dh.LIS3DH class. First you will need to import the libraries to use the sensor

from machine import Pin, I2C
from micropython_lis3dh import lis3dh

Once this is done you can define your machine.I2C object and define your sensor object

i2c = I2C(sda=Pin(8), scl=Pin(9))  # Correct I2C pins for UM FeatherS2
lis = lis3dh.LIS3DH(i2c)

Now you have access to the acceleration attribute

acc_x, acc_y, acc_z = lis3dh.acceleration

property acceleration¶: The x, y, z acceleration values returned in a 3-tuple and are in \(m/s^2\)

property axes_enabled¶

The data rate of the accelerometer. you could selected different axes to be on. Take a look at the table to select the Aces that you are interested in.

Mode	Value
`lis3dh.AXES_X`	`0b001`
`lis3dh.AXES_Y`	`0b010`
`lis3dh.AXES_X_Y`	`0b011`
`lis3dh.AXES_Z`	`0b100`
`lis3dh.AXES_Z_X`	`0b101`
`lis3dh.AXES_Z_Y`	`0b110`
`lis3dh.AXES_Z_Y_X`	`0b111`

property data_range¶

The range of the accelerometer. The LIS3DH has dynamically user selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5 kHz.

Mode	Value
`lis3dh.DATARANGE_2`	`0b00`
`lis3dh.DATARANGE_4`	`0b01`
`lis3dh.DATARANGE_8`	`0b10`
`lis3dh.DATARANGE_16`	`0b11`

property data_rate¶

The data rate of the accelerometer ODR <3:0> is used to set power mode and ODR selection. In the following table are reported all frequency resulting in combination of ODR<3:0>

Mode	Value
`lis3dh.DATARATE_1`	`0b0001`
`lis3dh.DATARATE_10`	`0b0010`
`lis3dh.DATARATE_25`	`0b0011`
`lis3dh.DATARATE_50`	`0b0100`
`lis3dh.DATARATE_100`	`0b0101`
`lis3dh.DATARATE_200`	`0b0110`
`lis3dh.DATARATE_400`	`0b0111`
`lis3dh.DATARATE_1344`	`0b1001`
`lis3dh.DATARATE_POWERDOWN`	`0b0000`
`lis3dh.DATARATE_LOWPOWER_1600`	`0b1000`
`lis3dh.DATARATE_LOWPOWER_5000`	`0b1001`
