Below is the electrical connection schematic of LIS302DL, an MEMS motion sensor 3-axis – ± 2g/± 8g smart digital
output “piccolo” accelerometer which capable to measure accelerations of 100Hz or 400 Hz output data rate. LIS302DL can be applied for
a variety of applications such Free-fall detection, Motion activated
functions, Gaming and virtual reality input devices, Vibration monitoring and compensation.
Through the I2C/SPI interface, you can see functionality of the LIS302DL and then measure the acceleration data
since this device has selectable and accessible functions through the
interface. Please high-tied of the CS when you use the I2C, according to
the datasheet. You can also completely program the functions, the
threshold and the timing of the two interrupt pins (INT 1 and INT 2)
through the same interface.
On the common design practice, you should place power supply decoupling capacitors
(100 nF ceramic, 10 µF Al) as near as possible to the pin 6 of the
LIS302DL since through the Vdd line the device core is supplied while
the I/O pads are supplied through Vdd_IO line. Have complete
