MPU9250 DMP Library for ESP32

Postby rupin.chheda » Mon May 06, 2019 4:54 am

I am working on a DIY joystick with an ESP32 and needed a IMU for motion tracking.
The Sparkfun Repo https://github.com/sparkfun/SparkFun_MP ... no_Library was one of the available libraries, but this library was made for the Razor DOF product of sparkfun, which has an SAMD core.

I have been able to modify the library and get good results with the ESP32. My fork and modifications are available here https://github.com/rupin/SparkFun_MPU-9 ... no_Library

If you have the IMU and the ESP32 with you, I would urge you to play with this library and give me feedback. Will submit a PR sometime in a couple of weeks once I am able to test the changes thoroughly.

Hello rupin.chheda, I'm trying your fork, the program normally compiles without any problem is written to ESP32. The setup is executed successfully, the MPU9250 module is found, but I am not receiving data from the module when the

Code: Select all

imu.dataReady ()
command is executed. I made some modifications to debug what is happening and I have identified that I am receiving an

Code: Select all

INV_ERROR (0x20)
response to the command.

The test form performed in a "Heltec WIFI_LoRa_32" and the module "GY-91"
