Software for the Access Control Nodes (ACNode) at the Makerspace Leiden.

RFID cards are coded as decimal numbers separated by a dash. So if the card contains

unsigned char uid[] = { 13, 70, 0, 33, 19 }; // In 'read from card' order.

then the seralisation into an ascii string wil be '13-17-0-33-19'.

• Master

  The master node and a sample database. Can be ran out of the box with

   ./master.py --debug --dbfile sample-keydb.txt 
  

• SimpleDeurNode

  A simple door RFID reader and stepper-motor lock combination. Can be tested/ran with the command

  ./acnode-deur.py --offline --debug 1-1
  

  The --offline command removes the hardware from the loop (see the top of the file for the GPIO settings); the '1-1' is a 'fake' card; see the above sample-keydb.txt

• DeurControlNode

  A node that has only the stepper engine to open the door connected. Run with:

  ./acnode-deur.py --offline --debug
  

• DeurRFIDNode

  A node that has just a reader attached.

  Test with the command (after starting above DeurControlNode.

  ./acnode-rfid.py --offline --debug 1-1
  

• KrachtstroomACNode

  A more complex node - which can control multiple tools.

• Drumbeat

  A test tool - just broadcast the timestamps.

• lib

  Library of shared files:

• lib/ACNode.py

Base class with the protocol and assorted sundry

• SensorACNode.py

• ActuatorACNode.py

• DrumbeatNode.py

  Classes on top of the ACNode that add the protocol bits for a sensor, actuator and the timestamps.

• OfflineModeACNode.py

  Provides the '--offline' functionality to allow testing on laptops (e.g. not require the specific RasberryPI & assorted hardware).

• RfidReaderNode.py

  Simple RFID reader; can also be ran 'stand alone' to test the RFID reader; e.g. with

    $ ./RfidReaderNode
    Detected card: 23-9-12-4-32
    Detected card: 3-71-5-21-81
    ctrl-C
    $
  

• lib/Drivers

• Mosfet.py

• Stepper.py

Directory with hardware/wiring specific drivers. These can be ran from the command line as well. e.g. use:

  ./Stepper.py 

to activate the stepper to open the door.

Currentl dependencyies for a `pip install' are:

wheel setuptools 

followed by (as otherwise dependencies can go funny):

daemon setproctitle configargparse python-axolotl_curve25519 ed25519 python-axolotl paho-mqtt pycrypto

Pip can generally be installed with

pkg install pip
port install pip
apt install python-pip

etc. On some platforms you will have to also install the headers; e.g.

apt install python3-dev

or similar.
