MPU6050 Accelerometer Gyro Temperature

@Jeremie,  thanks for the reply here is a picture of the setup.  The ezb4 is being power with 8.4 volts the MPU6050 is being powered by the 3.3V from the i2c port on the ezb4 the wire is about 17inchs long. The SDA and SCL pins have 330 resistors connected to the Vcc pin.

The sda pins on the ezb4 and the MPU connected together and the same goes for the scl pins.

Is there anything else I can provide for you.

In the skill it shows the temp but as soon as I click the int button in the skill it normally makes the red LED light up and stays on and the ezb4 disconnects from the network.

Thanks for the photos! 2 things:

1. Your wires may be too long I would look at shortening those.

2. It looks like you used 470ohm resistors in parallel with the onboard pull-ups, I would recommend going lower (220 ohms).

It looks like we have very similar boards. Here's my setup (works solidly):

8 inch cable:

220 ohm Pull-up resistors soldered in place of the original (2.2Kohm resistors) I believe:

Yeah, I also powered it from the EZ-B 3.3V.

I just use the example code from above for testing:

ControlCommand("MPU6050", Init)

:loop

ControlCommand("MPU6050", RunOnce)
  
sleep(100)

goto(loop)

@Jeremie, I installed the 220 ohm resistors and it is working great now thanks for your help!

DJ,  Is there anyway I can get the source for this skill I would like to see if I can enhance it for my project. by making a new version that is more feature rich.  Please let me know if this is something we can do.

Sure, here you go: MPU6050 Src.zip

This is not a plugin robot skill, which means it's part of ARC native. For you to make it a plugin, the code can be copied into the plugin template. You have to change the namespace.

DJ, Thanks but it looks like I am not going to be able to do this because my Windows 11 is on an Arm64 and you can only install Visual Studio 2022 Community for ARM64.  Based on what is posted there are issues with 2022 Community version.   But thank you for providing the source code.

Yeah Microsoft has a pretty big bug that they refuse to fix about that.

DJ, I am trying to understand which MPU6050 class you guys are using and what type of values that class is sending back so if you can provide any information on that class it would be a big help.  I just need to understand what type of pre processing the class is doing to the values.

The following code is from the MPU6050.cs file in the source you sent me.  Just as an FYI this skill is not returning the correct temp value.  I get a value of like 217c in the skill.

using System;
using System.Linq;

namespace EZ_B {

  public class MPU6050 {

    EZB _ezb;

    public MPU6050(EZB ezb) {

      _ezb = ezb;
    }

    public void Init() {

      _ezb.I2C.Write(0x68, new byte[] { 0x6b, 0x00 });
    }

    public Classes.MPU6050Cls GetData() {

      _ezb.I2C.Write(0x68, new byte[] { 0x3B });

      byte [] everything = _ezb.I2C.Read(0x68, 14).Reverse().ToArray();

      Classes.MPU6050Cls cls = new Classes.MPU6050Cls();

      cls.AccelX = BitConverter.ToInt16(everything, 12);
      cls.AccelY = BitConverter.ToInt16(everything, 10);
      cls.AccelZ = BitConverter.ToInt16(everything, 8);
      cls.TmpC = (BitConverter.ToUInt16(everything, 6) / 340) + 35;
      cls.GyroX = BitConverter.ToInt16(everything, 4);
      cls.GyroY = BitConverter.ToInt16(everything, 2);
      cls.GyroZ = BitConverter.ToInt16(everything, 0);

      return cls;
    }
  }
}
