according to AN3841 "Performing Offset Calibration using theMMA7660FC"
//Hold MMA7660FC on horizontal plane, put it in active mode and get the shift value
X_Shift = (64 times reading sum)/64*(-2)
Y_Shift = (64 times reading sum)/64*(-2)
Z_Shift = ((64 times reading sum)/64-21) *(-2)
My question is how to get the X_shift,Y_shift and Z_shift?
Is obtained from the register of REG00-REG02?
