AN3840, Setting up the MMA7660FC to do Orientation Detection
Freescale Semiconductor, Inc.
The MMA7660FC has the built in capability to do orientation detection. This feature gives the customer the capability to do applications such as portrait/landscape in mobile phones/PMP/PDAs. The tilt orientation of the device is in 3 dimensions and is identified in its last known static position. This allows a product to set its display orientation appropriately to either portrait or landscape mode or to turn off the display when the device is placed upside down. The sensor provides 6 different positions: left, right, up, down, back, and front, defined in Table 1 and Figure 1. “Orientation Detection Logic of when Interrupt will occur”. This application note will explain how to configure the MMA7660FC to do orientation detection given the desired sample rate or targeted power consumption.
