hello everyone,

Using MPU-9250 i want to detect whether person is sleeping, walking, running etc.. i came to know using AAR library i can do this.. but i didn't find any help/link/details related on how to use AAR library(except invensense documentation)with ARM cortex.. any example code? what are all the per-requisites ? how to dump the code to ARM cortex? etc...
