I2c In C# Not Reading Values

Skip to comments   Jump to end

I have mpu-6050 6dof imu. I want to read the value of who_am_i register with register number 0x75. The register returns address 0x68. But I am getting 255. The device address is 0x68 as well. Code is as follows:

byte[] ret = ezB_Connect1.EZB.I2C.Read(I2C.ReadArgsEnum.Auto,0x75,1);

here is the register description for the device:RM-MPU-6000A.pdf

I checked my imu with arduino and it works fine. So, any help here?

Hi I have mpu-6050 too and i try to read the value from C# and i have some problems...

I tried this command : ezB_Connect1.EZB.I2C.Read(I2C.ReadArgsEnum.Auto,0x75,1); and it does't work cause there is this method "I2C.ReadArgsEnum.Auto" more over the read method accept only 2 values.... Does it exist some where a sample to use the device mpu-6050 by using C# ?

Please share your code.

Also, in visual studio there is auto complete, which shows you the command syntax as you type.

Removed duplicate thread.

ps, i upgraded the EZ-SDK today - ensure you upgrade as well.

Now that i'm in front of a PC, here's example code...


  public class MPU6050Example {

    MPU6050  _mpu;

    public FormMPU6050() {

      InitializeComponent();

     // Create the mpu6050 object 
     // Include a reference to the EZB (most likely in your EZB Connection UserControl)
      _mpu = new MPU6050(ucEZBConnect1.EZB);
    }

    private void btnInit_Click(object sender, EventArgs e) {

      // Init is required before you can begin obtaining data
      _mpu.Init();
    }

    void getData() {

      try {

        EZ_B.Classes.MPU6050Cls response = _mpu.GetData();

        // do something with the data

      } catch (Exception ex) {

        // handle your exception
      } finally {

      }
    }
  }

Hi DJ Sures You are crédible :-) , i just ask a new api and you made it in few minutes. thank you very much. I have included your code in my visual studio and tried to print the value of the Gyro but the values of the gyro are initials

label2.Text = response.GyroX.ToString(); // value 0 label3.Text = response.GyroY.ToString(); // value 0

there is something wrong in my code i think. i keep on to look for and keep you inform thank you again. tired
