support of 2 sensors

[76nic]

Dear Romain,
I really like the work you have done on the library MPU6050_light. Would you consider to add support of 2 MPU sensors. Basically calling all the functions you have currently implemented with "mpu0x68.xxx" and "mpu0x69.xxx".
Many thanks in advance for thinking about it!
Best regards,
76nic

Hello 76nic,

As far I understand your issue as already been solved. Please have a look at the previous issue here.
You can also have a look at the release version 1.2.1 which solved the two sensors issue.

Please tell me if this helps

Cheers,

Romain

Dear Romain, many thanks for your responds and pointing me to the mpu.setAddress() functionality. I have a question regarding the mpu.calcGyroOffsets() function using 2 sensors in parallel. Is the calibration done for both sensors and stored if I call that function? Basically like the following:

MPU6050 mpuA(Wire);
MPU6050 mpuB(Wire);
void setup()
    Wire.begin();
    mpuA.setAddress(104);
    mpuA.begin();
    Serial.println(F("Calculating gyro offset, do not move MPU6050"));
    delay(1000);
    mpuA.calcGyroOffsets();
    Serial.println("Done.");
    
    mpuB.begin();
    Serial.println(F("Calculating gyro offset, do not move MPU6050"));
    delay(1000);
    mpuB.setAddress(105);
    mpuB.calcGyroOffsets();
    Serial.println("Done.");
void loop()
    mpuA.update();
    currentAngleX_A = mpuA.getAngleX();
    currentAngleY_A = mpuA.getAngleY();
    currentAngleZ_A = mpuA.getAngleZ();

    mpuB.update();
    currentAngleX_B = mpuB.getAngleX();
    currentAngleY_B = mpuB.getAngleY();
    currentAngleZ_B = mpuB.getAngleZ();

Many thanks,

sorry - the code format turned out weird by uploading - it is meant as continues code.

Hello 76nic,

If you have two different MPU6050 cpp objects they evolve independently, so the calibration is independent.

Cheers,

Hello thank you for this code but may I know how would the code be like if it is for 5 sensors and not only 2 sensors? For this code 2 registers were used but what if it is for 5 sensors? Thank you so much.

To what pins should the other MPU connected to?
