Hello People, I have got a Problem with the MPU6050_DMP6 Code as it sometimes hangs when its running. It seems to stop randomly after some time and it makes no difference if i have the Arduino powered from USB, USB and Running Serial Monitor or from 9V Battery. I did minor changes to the code: Added Raw Values and Datalogging on a Micro SD Card with a Catalex Micro SD Adapter for Arduino and removed parts like TeaPot Demo and so one because i dont need them for my application. But i dont think this problem occus due to my changes because i think i saw this freezing also with the Basic MPU6050_DMP6 Code. I tried the Datalogging with SD-Library and SDFatLibrary but the Problem occured with both. The FIFO/DMP Rate is set to 25 Hz with 0x02, 0x16, 0x02, 0x00, 0x07 // D_0_22 inv_set_fifo_rate in the MPU6050_6Axis_MotionApps20 Library .h File because i had Fifo Overflow when runnig with 100Hz. Here is my sketch code: I added a Led on Pin 8 with indicates aktivity so i see the led stopping blinking once in a while when i run the code. If i have the serial monitor then it just stoppes writing new lines. Can somebody give me a hint why this happens and how it could be fixed? Or if somebody got a code for Datalogging Yaw Pitch and Roll Values + Raw Values Accelerometer and Gyroskop i would also appreciate very much! I also tried 2 differnet SDCards (one Class 10) and ther was no differnce... I really annoying because i want to log data and when it stops randomly and mostly after not more than 2 to 3 minutes the application is unreliable and useless.... Greets Julian
