- RaspberryPi
- Running Rasbpian
- ssh raspberrypi.local
- Running Rasbpian
Setup
Steps Taken
- Installed Raspbian on a 16GB SD memory card
- 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".
- 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.
- http://www.skpang.co.uk/blog/archives/575
- sudo adduser pi i2c
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))

- this article goes over how to use the internal pullup\pulldown resistors on the pi: https://github.com/quick2wire/quick2wire-gpio-admin/blob/master/README.md
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
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
