Overview
The PmodACL2 is a 3-axis digital
accelerometer module powered by the Analog
Devices ADXL362.
Features include:
•
•
•
•
•
user-selectable resolution
single or double-tap detection
activity and inactivity monitoring
free fall detection
SPI Communication
Functional Description
Connector J1 – SPI Communications
Pin Signal Description
The PmodACL2 uses a standard 12-pin
connector and can communicate via SPI.
While the ADXL362 is in Measurement Mode,
it continuously measures and stores
acceleration data in the X-data, Y-data, and Z-
data registers.

Interface
All communications with the device must
specify a register address and a flag that
indicate whether the communication is a read
or a write. Actual data transfer always follows
the register address and communication flag.

Description
The SPI standard uses four signal lines. These
are slave select (~SS), master out slave in
(MOSI), master in slave out (MISO), and serial
clock (SCLK). These four signal lines map to
the following signals on the ADXL345: ~SS
corresponds to the chip select signal (~CS),
MOSI corresponds to serial data input (SDI),
MISO corresponds to serial data output (SDO),
and SCK corresponds to the serial clock
Perform device configuration by writing to the
control registers within the accelerometer.
Access accelerometer data by reading the
device registers.
You may find a full list of registers, their
functionality, and communication specifications
in the ADXL362 datasheet available at:
www.analog.com.
(SCLK). (See Table 1 for signal descriptions.)
