Freescale is now offering the next-generation ZSTAR3 with the MMA7660FC accelerometer that offers extended functionality. New software has been developed to allow the user to tap, shake or orient the device with the MMA7660FC for specified commands. The ZSTAR3 system accommodates multiple digital and analog accelerometer boards, connected through an RF ZigBee® 2.4 GHz communication to a single USB node connected to a PC. The accelerometer boards measure acceleration in three axes using a pin-compatible digital or, optionally, an analog sensor. The sensor sensitivity is defined by the selected accelerometer. The USB node is part of the ZSTAR design, equipped with dedicated software supporting multiple nodes.
