Thanks to Jeff for his work ! I couldn't even try using DMP without his code...
The MPU6050_raw works well with my sparkfun mpu6050 connected to an arduino uno. The MPU6050_DMP6 has an irregular behavior. When launching, the serial monitor says "DMP ready! Waiting for first interrupt...", and indeed it waits a pretty long time... The interrupt pin is connected to arduino pin 2 I've also tried to connect the vio to arduino 3.3v The point is that I've no interrupt signal when connecting an oscilloscope on INT pin of the mpu... is there a hardware issue ? or should I initialize something in the mpu ?
Thanks for your response
