This means that your string needs to have space for one more character than the text you want it to contain. Acceleration and rotation sensors are most known from smartphones. Therefore, the mpu9250 just sends garbage (typically this is either 00000000 or 11111111 but it can be even an old number stored). It's easily seen that the filter (red) follows the gyroscope (blue) for fast changes, but keeps following the mean value of the accelerometer (green) for slower changes, thus not feeling the noisy accelerometer data and not drifting away eiter. You can easily wire this breakout to any microcontroller, we'll be using an Arduino. I think if I wanted the MPU9250 to work well the best way to do it would be design a very small PCB that had the MPU9250 and a small ARM processor on it where the data was feed out of the MPU9250 into the ARM processor at high freq SPI then the ARM processor performs the Madgwick fusion filter and makes aviable both the raw data and fused data. Cheers! What if I have this working codes, how will I edit this to connect more than two MPU9250? Please guide me.

For regular data collection the SensorTag does not use any interrupt features provided by the sensors, but the movement sensor (MPU9250) uses interrupt for the wake-on-movement (shake detection). Now I am starting to read the SparkFun tutorials, then the datasheet. This is extremely unlikely in a real-world situation, and makes me think that the way you are reading registers and/or converting data for storage in your variables has a problem with (1) register read orders, (2) byte orders, or (3) bit orders. 1 - a Python package on PyPI - Libraries.
