Overview

  • RaspberryPi
    • Running Rasbpian
      • ssh raspberrypi.local

Setup

Steps Taken

  1. Installed Raspbian on a 16GB SD memory card
  2. Followed this guide to get I2C available
    • Used this article to determine that I had a 256MB Model B RaspberryPi. This is important, because when checking i2cdetect I have to use "-y 0" instead of the "-y 1".
  3. This article is good too, it mentions to add the pi user to the i2c group so you don't have to run sudo all the time.

Troubleshooting

  • Ran into this error when running DannyO's (hubcitylabs) poll.py script:

quick2wire/i2c.py", line 72, in transaction

   ioctl(self.fd, I2C_RDWR, addressof(ioctl_arg))
  • Problem Description: hubcitylab's poll.py script works on Rev1 RasbPi, doesn't work on Rev2
    • Solution: py532.i2c.py is hard coded to use "0" as the i2c_channel. This needs to be updated to "1" for Rev2 boards, or better yet, have it check which bus is in place and use the correct I2C bus location via detection.
    • Better Solution: the libraries downloaded with the git clone of the hikaru-gatekeeper are not the latest. make sure to download the latest libraries (quick2wire, py532, possibly others) independently to get code that will work on Rev2 raspberry pi boards
  • Rooted Galaxy S3, NFC reader still does not see phone. Mog suggested that an application might have to be running that will broadcast the NFC ID. --Omegix (talk) 21:13, 31 July 2013 (CDT)
    • When running NDEF Tools on my rooted (may not matter) GS3, the NFC ID was broadcast.
    • The Galaxy S4 (Four) writes a different NFC tag each scan.

Resources

Python Approach

  • usbScan.py
    • Script will continuously scan for new USB devices, and call ldap Check. If ldap check successful, call DoorUnlock.
  • nfcScan.py
    • same as usbScan.py, except for NFC (and RFID)
  • ldapCheck.py
    • Take in value, see if it's in the LDAP
  • DoorUnlock.py
    • Throw pins high and low on the GPIO to trigger relays that will be tied to a powerbolt1000.
    • Monitor pins wired to reed switches to ensure door is closed before re-locking.
    • Pin Assignments
      • Relay for Door Unlock (IN1 on Keyes Relay Board): #23 on GPIO
      • Relay for Door Lock (IN2 on Keyes Relay Board): #24 on GPIO
  • ScanReedSwitch
    • Pin Assignments: #25 on GPIO
  • Willie IRC Bot Framework
    1. install from github, tarball may not be latest
      • Install Dependencies: sudo apt-get install python-lxml python-mysqldb python-tweepy python-feedparser python-enchant; sudo pip install pytz praw
    2. run sudo ./setup install to install modules

Perl Approach

  • Would have to write an PN532 driver in perl
  • Alternatively have perl call python scripts, python already has a PN532 driver written
  • Write a new ackis module for NFC monitoring
