Which datasheet (pdf) did you refer to?
Yours is the only library having WHO_AMI_I register at 0x77 and the only library which is working with my CJ sensor.

The code for magnetometer reading must be fixed. The byte order is incorrect according to datasheet. The code should read:

`/**

• @brief Read readings from magnetometer.
  */
  void MPU9255::read_mag()
  {
  requestBytes(MAG_address, MAG_XOUT_L, 8);//note we must request 8 bytes of data because otherwise it does not work

uint8_t rawData[6];
readArray(rawData,6);

mx = ((int16_t)rawData[1] << 8) | rawData[0];
my = ((int16_t)rawData[3] << 8) | rawData[2];
mz = ((int16_t)rawData[5] << 8) | rawData[4];
}
`

well, i only know a few pin like
VCC (imu sensor) -> 5v (arduino)
GND (imu sensor) -> GND (arduino)

but i still dont know where to insert
SDA
SCA
INT
FSYNC

please give more info about it, thank you

i used your lib with TI CC1350 CC1310.
I couldn't compile because enum interrupts {...} was conflicting with core function void interrupts().
To avoid further conflicts may be it is better to rename enum interrupts to mpu_interrupts.
After following changes it worked for me:
// change in MPU9255.h:
// //interrupt pin settings
// enum interrupts {...}
// to
// enum mpu_interrupts {...}
//
// and in and MPU9255_Interrupts.cpp:
// enable_interrupt_output(interrupts selected_interrupt)
// disable_interrupt_output(interrupts selected_interrupt)
// to
// enable_interrupt_output(mpu_interrupts selected_interrupt)
// disable_interrupt_output(mpu_interrupts selected_interrupt)

Dear maintainer,

Can you please apply the pull request I made, so people can use your library, and I can delete the fork.

For anyone who want the fixed version until the maintainer of this library fixed the problem, you can you the fixed version:

Hi, I tried using your library but the mx, my, mz values are -1 in raw and -15 in dataprocessing. I am using mpu 9250/9255 with ic mp95.
