esp32 mpu9250

[carbonadam]

Any chance for a version without the sensor hub? eek:)

[kriswiner]

A version of what?

A sketch for the mpu9250 for the esp32 using the Madgwick and/or Mahony filters

close enough

I managed to get this one of yours to work https://github.com/kriswiner/MPU9250/blob/master/MPU9250BasicAHRS.ino

Though its not written specifically for the esp32. I wonder how this compares to the sensor fusion hub output?

[kriswiner]

4 degree heading accuracy rather than 2 degree with the EM7180.

Outstanding:) Any increases in accuracy if I was to use the floating point available on the esp32? Preferring this for the moment over the bno55.

[kriswiner]

Accuracy will depend more on how well you calibrate the sensor, but if you can run the fusin algorith at >> 1 kHz this can only help.

The BNO055 is not a good solution.

Right Calibration. Any tips to calibration using the code version I used?

[kriswiner]

Use the code version I linked to.

Hmm, compiling that seems to give me a bunch of problems with the librarys..any hints?

[kriswiner]

Put the quaternion filter file in the main sketch tab?

more todo with the ESP8266WebServer.h: and queue.h..file not found..even though I copied in those libs

[kriswiner]

Commen out the offending lines then.

got as far as commenting out the offending temperature and pressure reading..it compiles but no sensor readings updating ax = 0.00 ay = 0.00 az = 0.00 mg gx = 0.00 gy = 0.00 gz = 0.00 deg/s mx = 0 my = 0 mz = 0 mG q0 = 1.00 qx = 0.00 qy = 0.00 qz = 0.00 Gyro temperature is 28.7 degrees C Digital temperature value = 0.00 C Digital temperature value = 32.00 F Digital pressure value = 0.00 mbar Altitude = 145366.45 feet Yaw, Pitch, Roll: 13.80, 0.00, 0.00 Grav_x, Grav_y, Grav_z: 0.00, 0.00, 1000.00 mg Lin_ax, Lin_ay, Lin_az: 0.00, 0.00, -1000.00 mg rate = 158308.53 Hz ax = 0.00 ay = 0.00 az = 0.00 mg gx = 0.00 gy = 0.00 gz = 0.00 deg/s mx = 0 my = 0 mz = 0 mG q0 = 1.00 qx = 0.00 qy = 0.00 qz = 0.00 Gyro temperature is 28.7 degrees C Digital temperature value = 0.00 C Digital temperature value = 32.00 F Digital pressure value = 0.00 mbar Altitude = 145366.45 feet Yaw, Pitch, Roll: 13.80, 0.00, 0.00 Grav_x, Grav_y, Grav_z: 0.00, 0.00, 1000.00 mg Lin_ax, Lin_ay, Lin_az: 0.00, 0.00, -1000.00 mg rate = 158305.33 Hz

Use the calibration functions then in the first sketch that you got to work.
