NXP  D3172MMA7455L  开发套件, ZSTAR3, 加速度计

The is a demo board for MMA7455L three axis digital output accelerometer. The MMA7455L is a digital output I2C/SPI, low power, low profile capacitive micro machined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self test, configurable to detect 0g through interrupt pins INT1 or INT2, and pulse detect for quick motion detection. 0g offset and sensitivity are factory set and require no external devices. The 0g offset can be customer calibrated using assigned 0g registers and g select which allows for command selection for three acceleration ranges 2g/4g/8g. The MMA7455L includes a standby mode that makes it ideal for handheld battery powered electronics.
