#####The code output is raw value of acceleration in X, Y and Z Axis.

adxl345's Issues

I/O Error on this python code in raspberry pi 2

hi sir,
thanks for sharing this code.I have some doughts about this code.I run this same code in RPi board.after installing smbus and enabling I2C model.but it's showing i/o error, so please help me for this error.
the error is
[
pi@raspberrypi:~/Desktop/Nexsys $ sudo python ADXL345.py
Traceback (most recent call last):
File "ADXL345.py", line 6, in
bus.write_byte_data(0x53, 0x2C, 0x0A)
IOError: [Errno 5] Input/output error
]
my code is:

import smbus
import time

bus = smbus.SMBus(1)

bus.write_byte_data(0x53, 0x2C, 0x0A)
bus.write_byte_data(0x53, 0x2D, 0x08)
bus.write_byte_data(0x53, 0x31, 0x08)

time.sleep(0.5)

data0 = bus.read_byte_data(0x53, 0x32)
data1 = bus.read_byte_data(0x53, 0x33)

xAccl = ((data1 & 0x03) * 256) + data0

if xAccl > 511 :
xAccl -= 1024
data0 = bus.read_byte_data(0x53, 0x34)
data1 = bus.read_byte_data(0x53, 0x35)
yAccl = ((data1 & 0x03) * 256) + data0
if yAccl > 511 :
yAccl -= 1024
data0 = bus.read_byte_data(0x53, 0x36)
data1 = bus.read_byte_data(0x53, 0x37)
zAccl = ((data1 & 0x03) * 256) + data0
if zAccl > 511 :
zAccl -= 1024

Output data to screen

print "Acceleration in X-Axis : %d" %xAccl
print "Acceleration in Y-Axis : %d" %yAccl
print "Acceleration in Z-Axis : %d" %zAccl

thanks,

Concatenate several devices

I need to Concatenate 10 accelerometers to read acceleration simultaiusly using one I2C line
How can I do this?
