I'm trying to read the values ??of MPU6050 and do not know if they will be right. First are the values ??vary between 0 and 255 (high and low) and not between -128 and 127. As soon as I did not give negative but positive numbers. The first table was made with MPU6050 vertically and to the right and the second table is vertical and to the left.

Hello I would like to know if I'm doing a reading at the correct values ??MPU6050??
my values ??vary between 0 and 255 and not between -128 to 17.

This position:
GyroX
GyroY
GyroZ
AcelX
Acely
AcelZ
And i reading 10x.
This set of 10 values ??were taken with MPU6050 vertically facing to the right.

And this set of 10 points were taken with MPU6050 vertically facing to the left.

The problem that you have not shared with us is probably in the program that you have not shared with us.

4

The question makes no sense without seeing your code and wiring schematic and even then it will be difficult to comment as your environment will be different to everyone elses.

THIS IS MY PRINCIPAL CODE

//valor1 -> GyrX = low ; valor1H-> GyrX= high ;
//valor2 -> GyrY = low ; valor2H-> GyrY= high ;
//valor3-> GyrZ= low ; valor3H-> GyrZ= high ;
//valor4-> AcelX = low ; valor4H-> AcelX= high ;
//valor5-> AcelY = low ; valor5H-> AcelY= high ;
//valor6-> AcelZ = low ; valor6H-> AcelZ= high ;

GYRO_XOUT_OFFSET=(valor1H<<8 ) + valor1;
CalibrateGXX[index]=GYRO_XOUT_OFFSET;
GYRO_YOUT_OFFSET=(valor2H<<8 ) + valor2;
CalibrateGXY[index]=GYRO_YOUT_OFFSET;
GYRO_ZOUT_OFFSET=(valor3H<<8 ) + valor3;
CalibrateGXZ[index]=GYRO_ZOUT_OFFSET;

ACCEL_XOUT_OFFSET=(valor4H<<8 ) + valor4;
CalibrateAXX[index]=ACCEL_XOUT_OFFSET;
ACCEL_YOUT_OFFSET=(valor5H<<8 ) + valor5;
CalibrateAXY[index]=ACCEL_YOUT_OFFSET;
ACCEL_ZOUT_OFFSET=(valor6H<<8 ) + valor6;
CalibrateAXZ[index]=ACCEL_ZOUT_OFFSET;

How are you getting the values from the device ?

7

Do not post the same question twice.

8

I'm getting through the I2C protocol.
I wanted to know was how the values ??vary and intermediate points or origins points. Learn why the numbers

9

When the device is sitting still, the accleration values will indicate which way the gravity is pulling on the sensor element.
If it is sitting flat on the table, one direction will be sometning like 16000 and the other 2 values zero.

The gyro values will indicate rotation. when it is sitting still, they should be close to zero.

10

What do you say about my valors?

There is page with samples so you can see how much noise they have:
