Introduction

CircuitPython helper library for the QMI8658C 6-DoF Accelerometer and Gyroscope

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device
• Register

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing from PyPI

Note

This library is not available on PyPI yet. Install documentation is included as a standard element. Stay tuned for PyPI availability!

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install qmi8658c

Or the following command to update an existing version:

circup update

Usage Example

import time
import board
import qmi8658c

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

# If board.I2C is not defined, select the actual I²C pins. eg: SDA=GP6, SCL=GP7
# import busio
# i2c = busio.I2C(board.GP7, board.GP6)

sensor = qmi8658c.QMI8658C(i2c)

while True:
    ac = sensor.acceleration
    gy = sensor.gyro
    print(f"Acceleration: X:{ac[0]:.2f}, Y:{ac[1]:.2f}, Z:{ac[2]:.2f} m/s^2")
    print(f"Gyro X:{gy[0]:.2f}, Y:{gy[1]:.2f}, Z:{gy[2]:.2f} rad/s")
    print(f"Temperature: {sensor.temperature:.2f} C")
    print("")
    time.sleep(1)

Usage Note

Accelerometer low power(LP) mode must be a gyro disabled.

sensor.gyro_enable = 0
sensor.accelerometer_rate = AccRate.RATE_LP_21_HZ
