Mcube MC3635 Quick Start Manual And Demo

GENERAL DESCRIPTION
The MC3635 is an ultra-low power, low-
noise, integrated digital output 3-axis
accelerometer with a feature set optimized
for wearables and consumer product
motion sensing. Applications include
wearable consumer products, IoT devices,
user interface control, gaming motion input,
electronic compass tilt compensation for
cell phones, game controllers, remote
controls and portable media products.
The EV3635B is a prebuilt circuit board with
MC3635 3-axes sensor. The MC3635 has
internal sample rate from 14 to 1300
samples / second and measures
acceleration with a wide usage range, from
+/-2g up to +/-16g, and 6-bit to 14-bit high
precision ADC output, which is easy to fit
on top of the microcontroller, such as an
Arduino. The accelerometer communicates
via I2C/SPI and gives out motion detection
or sample acquisition conditions to trigger
an interrupt toward an MCU.
The sensor data is easily readable by
connecting DVDD to 3.3V, GND to ground,
and SCL/SDA pins to your Arduino I2C
clock and data pin respectively. Download
the MC3635 library from GitHub onto the
board, run the example sketch, and then
sensor data shortly comes out in raw data
count and SI unit accelerometer
measurements. An easy-to-use
demonstration on EV3635B using the
Arduino platform is included in this
document.
