Our design includes a MMA8652 for which the Z axis MSB is showing as being maxed out (-128) even though I can read the other two axis fine. Any suggestions as to what this may be? We developed the code using the sensors development board and the Z-axis can be read fine on that. The only hardware difference I can see is the marking between the chips the one that works has the marking 6522XZ the two that don't are 6524XY. Thanks in advance.
