@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,

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

@robski

Thanks, I'll have a look.

@Merlin513 Hi!
I have used 2.3.3 for months, and there is a new 2.3.4.
I have an 'old' AtomS3.
This is not usually a problem!
What sketch are you running?

@HappyUser
I guess it is directly connected to some hardware pin, so it may not be controlled by the user.
Or you can check the schematic and write high and low levels to all LED pins connected to GPIO to try it.
