Introduction
Provides access to onboard sensors and battet
Dependencies
This driver depends on:
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()
