Incompatibility between SparkFunMPU9250-DMP.h and U8g2lib.h

[froussel]

`/* Go to your SparkFun library (this is usually Documents\Arduino\libraries\SparkFun_MPU-9250-DMP_Arduino_Library-master)
navigate to src\util and edit the file
inv_mpu.h Somewhere at the beginning of file, just below the line that says
#define INV_MPU_H
add the following line:
#define min(X, Y) (((X) < (Y)) ? (X) : (Y))

This sketch works but if we uncomment
#include <U8g2lib.h> The esp8266 reboot
Sparkfun doesn't seem to be interested in its library anymore and I think it's her who is at fault
line
if (imu.begin() != INV_SUCCESS)
is the cause and if I go to the SparkFunMPU9250-DMP.h library it's on line 46
result = mpu_init(&int_param);
which reboots
mpu_init is in inv_mpu.c
Then I don't know how to track
Thanks for you help

Not sure how I can help here....

I understand that but a reader maybe ;-)
