Hi,

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?
