py532 with i2c

[nancy]

Hi

I am connecting adafruit pn532 nfc reader with the raspberry pi. I want to read the tag data using python script. I am using the example http://hubcitylabs.org/nfc-on-raspberry ... b-and-i2c/

i have enabled i2c on pi and with sudo i2cdetect -y 1 it is giving:

0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- UU -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --


I have already installed pn532lib, python3 but now when i am executing sudo python reader.py, it is giving following error:
File "reader.py", line 5, in <module>
from py532lib.i2c import *
ImportError: No module named i2c

Can anyone help me with this?

Regards
Nancy

You have to set PYTHONPATH environment variable.

For example,
1. Add PYTHONPATH in your ~/.bashrc file

Code: Select all

PYTHONPATH="${PYTHONPATH}:/path/to/pn532lib"

2. Add PYTHONPATH in your code

Code: Select all

import sys
sys.path.append("/path/to/py532lib")

good luck for your project : )
