Taking ARM-LPC1788 as core of embedded chip platform

by using MPU6050 9-axis motion sensor

through the successful transplantation of digital motion processing（DMP） databases and calculation of quaternions

and accurate and reliable date are obtained. Generalized extended interpolation model is used to optimize and process data to eliminate jitter error

in order to make the attitude value more stable.The results show that this system can real-time collect the exact attitude information of current device in real time

the measurement deviation is less than 0. 1 °

and it is able to work reliably and stably

which provides more stable and accurate reference standard for embedded systems that needs posture information.
