2 years ago `/* 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))
and the library is good for ESP266 and ESP32
now with ESP8266 Wemos D1 Mini

This sketch works but if we uncomment
include The esp8266 reboot
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
Hello,
I use
include
include
include
include
include
include "OneButton.h"
if I run screen u2g2lib, chrono, onebutton in first : no problem After ESP8266 wemos D1 mini reboot with result = mpu_init(&int_param); in SparkFunMPU9250-DMP.cpp
what is the solution please ?
