Hi! First of all, thank you very much for your very versatile library.
I tried to search before posting the question, without any luck, but still I fear this is a common question which I am going to ask again...
Is there any way to change the sample rate with this library?
I'd like to modify the frequency of my MPU6050

The BMM150 can be connected to the BMI160, allowing for the magnetometer data to be read via the BMI160 along with gyro and accel.
I have searched and been unable to find any libraries supporting this properly, will you consider adding support for this?

Hi,
trying Calibrated_sensor_output.ino with an esp32 and an MPU6886

MPU6886::calibrateAccelGyro() fails to read back the FIFO sample count here - the readBytes() request is NAK'd, hence fifo_count is zero, resulting in a divide-by-zero here

not sure what to do about it, short from replacing gyro calibration with averaging

thanks!
Michael

Hi,

During testing, I found that my esp32 was crashing when using the MPU9250 from your library.
I found the issue to be that in F_MPU9250.cpp, the function int MPU9250::initMagnetometer() doesn't return an int.

Cheers!

I have a BMI270, want it word on Arduino nano, other library is too big, hex too large, can't upload to Nano.

The magnetometer for my unit cannot use the the set pass mode from the code. Hence I suggest we used this code

writeByte(IMUAddress, MPU6500_INT_PIN_CFG, 0x02);	//enable Magnetometer bypass
writeByte(IMUAddress, MPU6500_INT_ENABLE, 0x01);    // Enable data ready (bit 0) interrupt

**Before this the code use 0x22 to enable Magnetometer to bypass.

I'm trying to port my source code to Platformio and encountered couple of weird things

1. First of all it can't be found in Platformio library search
2. Platformio "ignores broken library manifest"

3. For now, I can't build my project directly using the library from github

Was used

MPU6050 IMU;

I am using arduino nano 33 iot board and when IMUIdentifier Example is run,
Output is
=========== IMU Identifier =========== No IMU detected ======================================

So I am thinking if all the IMU's structure components are assigned correctly?
IMU {Address1, Address2, Register, ExpectedID, IMUName, IMUCapabilities} ==> {0x6B, 0x6A, 0x0F, 0x6A, "LSM6DSL", "3A,3G"}

FastIMU does not work with the builtin IMU of the Nano 33 IoT because the "who am i" value of the LSM6DS3 on the 33 is (or can be?) 0x6C instead of 0x69.

Using FastIMU 1.2.6, Calibrated_sensor_output example, on Arduino 2.3.2 with MPU6886 built into M5StickC Plus2. Runs fine if I comment out the Calibration line. If I let it try to calibrate I get:

Rebooting...

Update 6/3/2024
The Calibration works fine with an IMU6050 connected via I2c on a Wemos D1 Mini.

Does this library work with BMX160? and give our calibrated Quaternion output?

Because the sensor is not mentioned in the comments.

Thanks.

Qmi8658 is low price and high performance 6dof imu.

Is my problem?🤔
Thanks.

I have a MPU-6050 and was trying to make it work with FastIMU, unfortunately i get an error code of -1, that lead me to thinking that my sensor was broken, but when I try to read raw data from it I get a response, also when I scan i2c connections i get a positive one at address 0x68

(Image of output from Nick Gammon's i2c scanner)

(Image of output from the IMU identifier)

What units of measurement does this library output? Is the acceleration in Gs or m/s^2? Is the gyro data in rad/s?
