使用smbus在Raspbery Pi 3中使用I2C

我試圖將我的加速計ADXL3458連接到運行在ubuntu mate中的Raspberry Pi 3。我已經安裝了I2C通信所需的所有必要軟件包。當我執行這個命令i2cdetect -y 1我得到了這個結果。使用smbus在Raspbery Pi 3中使用I2C

現在我運行此Python代碼

#!/usr/bin/env python 

import smbus 
import time 
import math 
from math import sin, cos, pi 

bus = smbus.SMBus(1) 

print bus 

ACC_ADRESS = 0x53 

acc_x = 0.0 
acc_y = 0.0 
acc_z = 0.0 


def writeACC (register, value): 
    bus.write_byte_data(ACC_ADRESS, register, value) 
    return -1 

def readACC_byte (addr): 
    return bus.read_byte_data(ACC_ADRESS, addr) 


def readACC_word (addr): 
    LSB = bus.read_byte_data(ACC_ADRESS, addr) 
    MSB = bus.read_byte_data(ACC_ADRESS, addr + 1) 

    val = (MSB << 8) | LSB 
    return val 


def setupACC(): 
    # Sleep mode 
    writeACC(0x2D, 0) 
    # Mesurement mode 
    writeACC(0x2D, 8) 
    # enable Autu sleep mode 
    writeACC(0x2D, 16) 

    while True: 
     time.sleep(0.1) 
     acc_x = readACC_word(0x32) 
     acc_y = readACC_word(0x34) 
     acc_z = readACC_word(0x36) 

     print "Acc_x :\n", acc_x 
     print "Acc_y :\n", acc_y 
     print "Acc_z :\n", acc_z 

     time.sleep(0.5) 


if __name__ == '__main__': 
    setupACC()

而且我示波器
