@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.

@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!

@xgonc

SoftwareSerial mySerial(1, 2); void setup() { mySerial.begin(115200); } void loop() { mySerial.write("Hello world!"); }

@mdseldon
are you able to access the serial log?

@mgrouch I can use the M5Unified library to read a reasonable readings from the BMM150. Yet have to work on the orientation. In my case I have to invert the X-axis value and Z-axis value and able to calculate into a tilt-compensated headings

@ewoodier84
I don't know way to do the with out Linux.
I used Linux on virtual environment in windows.
How about trying virtual environments like Hyper-V or VirtualBox?

Meanwhile I can confirm that the method described by @kuriko worked for me 100%!
I had two "bricked" QR-Code2 scanners and both are alive again!

@konacurrents Note, I have a similar startup issue with the Atom Socket and H-Driver.

Anyone know how to stop it starting before I get a change to stop it?

@kuriko thanks for the reply, as I wrote on post n. 1,

@cepics said in AtomS3R Camera & esp_camera.h example:

I can upload and run the camera.ino

for my project I need to take picture and display it in a web page....

Hi @felmue

Ok, than next option would be simbase.com. They offer Sim Cards also for individuals. Prices seem a bit higher... Covererage is given also for Italy.
Anyone has experience with this service?

Thanks, flori

@felmue Thanks Felix. I see now...

@patf said in AtomS3R IMU and magnetometer calibration:

@mgrouch Hi there, the M5Unified library has a calibration routine that works well. See the IMU example in the library, and make sure to read all of the comments carefully.

You press the Atom BtnA (screen) and it will calibrate for 10 seconds, enough to do one axis at a time. You are best to calibrate the accelerometer, gyro and magnetometer separately for best results.

Personally I modified the example so that the calibration starts on press BtnA, and ends on the second press of BtnA. i.e. no 10 second countdown. This way I can take my time and calibrate all 3 axes of each sensor (accl, gyro, or mag) in one continuous movement.

I looked at the calibration code in m5unified library. It doesn't look right to me.
There is no sphere fit being performed. Only offset biases are estimated.
What about scale biases?

Thanks

@lewissykes

I wrote code which seems gives 9-axis including magnetometer
