@yuyun2000 Thank you for your response. I will try it out with Arduino as soon as possible.

Just a quick question to make sure we're on the same page. We are talking about the integrated IMU in the AtomS3R, no external accelerometer, right?

I will try to find more details in the documentation, but as far as I can see, the only place where the IMU is mentioned in the schematics is the IMU_INT that's connected to this XTAL_32K_N.

I will update you as soon as I have news.

Hi all,

Is it possible to use the UIFlow 2.0 API to put the AtomS3R into deep or light sleep mode and then to wake it up if the accelerometer registers a large enough acceleration?
I'm a total noob, but I saw in the schematics that the IMU INT line is connected to something (XTAL_32K_N) so it should be possible somehow, right? But I saw nothing in the API for this.

If it's not possible with UIFlow 2.0, is it perhaps doable with Arduino?

@teastain thx for the hint! It's just as you said about acceleration.

Btw: UIFlow works. I just installed the incorrect firmware (UIFlow2.0 instead of UIFlow2.0 AtomS3R).

Thanks again everyone!

Thanks for answering, guys.
I tried the Arduino example as suggested by @kuriko and indeed I get non-zero readings! So maybe @felmue is right to assume that UIFlow2 doesn't fully support M5AtomS3R yet.

The IMU readings don't make a lot of sense to me yet, I will next try to calibrate with this example code:

Hi everyone,
I bought an ATOMS3R, and burned the UIFlow2.0 ATOMS3R firmware on it. In UIFlow 2.0 I tried to print the accelerometer and gyroscope readings with below code.
However, the readings are all zero regardless of how I move or shake the ATOM. Did I miss an initialization or calibration step?

import os, sys, io
import M5
from M5 import *
import time

accel = None
gyro = None


def setup():
  global accel, gyro

  M5.begin()


def loop():
  global accel, gyro
  M5.update()
  acc_x, acc_y, acc_z = Imu.getAccel()
  gyro_x, gyro_y, gyro_z = Imu.getGyro()
  print(f'accel: {acc_x}x, {acc_y}y, {acc_z}z')
  print(f'gyro: {gyro_x}x, {gyro_y}y, {gyro_z}z')
  time.sleep(1)


if __name__ == '__main__':
  try:
    setup()
    while True:
      loop()
  except (Exception, KeyboardInterrupt) as e:
    try:
      from utility import print_error_msg
      print_error_msg(e)
    except ImportError:
      print("please update to latest firmware")
