External Frame Sync (FSYNC) in MPU6050::dmpInitialize()

Recommended Posts



can anyone explain me why Jeff Rowberg


1. set the FSYNC-Register, in the MPU6050_6Axis_MotionApps20.h / Function uint8_t MPU6050::dmpInitialize() row 404,  to      Extern_Temp_out_L and


2. the  Gyro Range to 2000 instead of 250?


Thx for your reply.

The only reasoning behind the code contained in the dmpInitialize() method is that it imitates the behavior captured from the official InvenSense MPU-6050 evaluation board and ARM controller which I had access to back in 2011. The captured and analyzed data can be found here:
I am not 100% certain whether every one of these I2C transactions is truly necessary.
