`bma423`¶

BMA423 Bosch Accelerometer CircuitPython Driver included in the Lilygo Watch V3

class bma423.BMA423(i2c_bus: busio.I2C, address: int = 0x19)[source]¶

Driver for the BMA400 Sensor connected over I2C.

Parameters:¶

Raises:¶

RuntimeError – if the sensor is not found

Quickstart: Importing and using the device

Here is an example of using the BMA423 class. First you will need to import the libraries to use the sensor

import board
import bma423

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

i2c = board.I2C()  # uses board.SCL and board.SDA
bma = bma423.BMA423(i2c)

Now you have access to the attributes

accx, accy, accz = bma.acceleration

property acc_range : str¶

Sensor acc_range

property acceleration : tuple[float, float, float]¶: Acceleration :return: acceleration

property filter_performance : str¶

Sensor filter_performance

Mode	Value
`bma423.CIC_AVG`	`0x00`
`bma423.CONT`	`0x01`

property output_data_rate : str¶

Sensor output_data_rate

property oversample_rate : str¶

Sensor oversample_rate. Bandwidth parameter, determines filter configuration (acc_perf_mode=1) and averaging for undersampling mode (acc_perf_mode=0)

property temperature : float¶: The temperature sensor is calibrated with a precision of +/-5°C. :return: Temperature
