Introduction

Provides access to onboard sensors and battery charge management circuitry

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Adafruit's LSM6DS library:

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 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 seeed_xiao_nrf52840

Or the following command to update an existing version:

circup update

Usage Example

import array
import time

import audiocore
import audiopwmio
import board

from seeed_xiao_nrf52840 import IMU, Mic, Battery

with Battery() as bat:
    print(f"Charge_status: {bat.charge_status}")
    print(f"Voltage: {bat.voltage}")
    print(f"Charge_current high?: {bat.charge_current}")
    print("Setting charge current to high")
    bat.charge_current = bat.CHARGE_100MA
    print(f"Charge_current high?: {bat.charge_current}")

with IMU() as imu:
    for i in range(5):
        print("Acceleration:", imu.acceleration)
        time.sleep(1)

with Mic() as mic:
    for i in range(5):
        print(f"Start speaking in: {5-i}")
        time.sleep(1)
    b = array.array("H")
    for i in range(8000):
        b.append(0)
    print("SPEAK!!!")
    mic.record(b, len(b))
    print(b)
    for i in range(5):
        print(f"Replaying in: {5-i}")
        time.sleep(1)
    with audiopwmio.PWMAudioOut(board.D0) as aud:
        print("PWM setup")
        sample = audiocore.RawSample(b, sample_rate=8000)
        print("sample ready")
        aud.play(sample,loop=True)
        print("playing")
        time.sleep(5)
        aud.stop()
