PyBMA400

A Python library for the Bosch BMA400 accelerometer, providing easy access to accelerometer data and configuration.

Installation

pip install pybma400

Features

Read acceleration data
Read temperature data in Celsius
Configure power modes, sampling rates, and ranges
Low-level register access for advanced users
Simple orientation detection functionality

Requirements

Python 3.6 or later
Raspberry Pi or other Linux system with I2C enabled
SMBus library (automatically installed as a dependency)

Usage Example

from pybma400 import BMA400

# Initialize the sensor
sensor = BMA400()  # Default I2C bus=1, address=0x14

# Read acceleration data
x, y, z = sensor.acceleration
print(f"Acceleration: X={x:.2f}, Y={y:.2f}, Z={z:.2f} m/s²")

# Read temperature
temp = sensor.temperature
print(f"Temperature: {temp:.1f}°C")

# Configure the sensor
sensor.power_mode = BMA400.NORMAL_MODE
sensor.output_data_rate = BMA400.ACCEL_100HZ
sensor.acc_range = BMA400.ACC_RANGE_4  # ±4g range
