Orangepi zero i2c and ina219 poblem

[Orangepi0]

Hello everyone,

I'm having some trouble with i2c  between orangepi zero and ina219. Here is i2cdetect -y 0 respons:
"     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --"

I'm using https://github.com/chrisb2/pi_ina219 and also installed https://github.com/adafruit/Adafruit_Python_GPIO and both of them installed without any problem, but when I run: 

"from ina219 import INA219, DeviceRangeError
from time import sleep

SHUNT_OHMS = 0.1
MAX_EXPECTED_AMPS = 2.0
ina = INA219(SHUNT_OHMS, MAX_EXPECTED_AMPS, address=0x40)
ina.configure(ina.RANGE_16V)

def read_ina219():
    try:
        print('Bus Voltage: {0:0.2f}V'.format(ina.voltage()))
        print('Bus Current: {0:0.2f}mA'.format(ina.current()))
        print('Power: {0:0.2f}mW'.format(ina.power()))
        print('Shunt Voltage: {0:0.2f}mV\n'.format(ina.shunt_voltage()))
    except DeviceRangeError as e:
        # Current out of device range with specified shunt resister
        print(e)

while 1:
    read_ina219()
    sleep(1)"

 

I get:

"Traceback (most recent call last):
  File "zero.py", line 7, in <module>
    ina.configure(ina.RANGE_16V)
  File "/root/pi_ina219/ina219.py", line 164, in configure

  File "build/bdist.linux-armv7l/egg/Adafruit_PureIO/smbus.py", line 274, in write_i2c_block_data
IOError: [Errno 70] Communication error on send"

 

So does anyone know what to do to fix this error.

 

Thanks
