@kuriko Dupont, that looks promising. Thanks. For the 4 pins of the HDriver to the 4 pins on the M5Atom (and 2 other pins too) - I would need a female at one end, and a male at the M5 end. You gave me a good path forward.

@hacxx tryed still same

I too have the ATOM_SPK and the sample programs run but create no sound, even with the earphone jack. https://docs.m5stack.com/en/atom/atom_spk The PlayRawPCM program runs but no sound. Also the PlayMP3FromSD is missing files, such as AudioFileSourceSD.h. Has anyone got these to work? I can get the beep program here to work https://github.com/PaulskPt/M5Stack_M5Atom_EchoSPKR But it seems this program makes a constant hum sounds always, and the beep when button pressed. I assume the battery will die faster too. ps. What's up with tagging posts as being "OLD" - when it's a year ago, but the programs being tried are 4 years old. It sure seems to me that the "thread" of any issue, even decades old, should still be used to keep that context intact. Oh well..

Mine did exactly the same thing until I actually funded my OpenAI API account. Then it started working instantly.

@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? https://community.m5stack.com/topic/7445/m5atom-based-power-turns-on-briefly-before-user-code-runs

@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....
