MPU 6050 Freezing

[ej2026]

I'm trying to pull gyro data off an MPU 6050 using an Arduino Nano R4. When I run the code, it returns extremely accurate values, but then angle X locks at -90 degrees ang AngleY locks at 90 degrees. Sometimes the code runs perfectly for 5 minutes before it freezes, and sometimes it runs for half a second. Hitting the reset button locks it up instantly. I have to unplug power and plug it back in for it to run correctly for any amount of time. Any guesses on how to fix this? I've heard that grounding the AD0 pin on the gyroscope can sometimes work to fix this issue. As I was typing this, it ran for 5 minutes. When I restarted it to take a video, it ran for 30 seconds. It doesn't matter how much or little the gyro is moved. It always locks up.

#include <MPU6050_tockn.h>
#include <Wire.h>

MPU6050 mpu6050(Wire);

void setup() {
Serial.begin(115200);
Wire.begin();
Wire.setClock(400000);
Wire.setWireTimeout(3000, true);
mpu6050.begin();
mpu6050.calcGyroOffsets(true);
}

void loop() {
mpu6050.update();
Serial.print("angleX : ");
Serial.print(mpu6050.getAngleX());
Serial.print("\tangleY : ");
Serial.print(mpu6050.getAngleY());
Serial.print("\tangleZ : ");
Serial.println(mpu6050.getAngleZ());
}

Your picture is far too small to make out any salient details.

Much. Bigger. Please. MUCH.

@ej2026

it returns extremely accurate values,

How do you know the values are extremely accurate?

Did you solder the wires to the sensor cleanly? Post a closeup picture showing the soldering.

Did you use the upload file tool, the picture looks weird.

[ej2026]

Yes, I just dragged and dropped the pics

@ej2026

Yes

That would be "no."

I took a look at the library you are using, MPU6050_tockn. The code is wrong, often fails and is not worth ten minutes of your time, except possibly as an unfortunate learning experience. Take a look at all these issues, not fixed after many years.

Make sure your connections are cleanly soldered to the sensor board, and try this simple code to read out just the raw data. Keep in mind that the gyro reports rotation rates, not angles.

Don't do that, use the File Upload icon. See post 7.

I uploaded that code, and while the MPU6050 is sitting still, the values are jumping all over the place. I'll upload pics of gyro connections in a couple minutes.

Here’s the soldered connections on the MPU.
