The MMA7260QT has many unique features such as low power, low current, a quick turn on time, and 3-axis sensing with g-select all in a small QFN package. The STAR enables the user to quickly see many capabilities of the device along with application ideas to pursue. In addition, with data download capability, the STAR provides a quick way to prototype a software solution to gain a better understanding for the capability of the device.
A software program was developed to provide an interface as well as a development system. The software can be used for displaying the 8-bit ADC values sent through the RS232 connection, or utilized for analyzing accelerometer data to demonstrate end applications.
For a final design, the g-Select is best configured to additional I/O of a chosen microcontroller. Therefore, the sensitivity of the device could be easily changed with a quick change in the software. In addition, the software can be configured so that different sensitivities can be used for several applications, where the MCU drives the g-Select during different modes of operation.
