general setup notes for the parts involved in “quartet”

  1. turn on wireless
  2. check its on the network (…)
  3. find its ip#
  4. turn on the cerf, wait
  5. find the cerf's ip#
  6. connect to the cerf using ssh (eg. ssh -lroot
  7. insmod adxl.o (this only has to be done when it startsup)
  8. when something is listening for sensor data (on port 5333, eg. oZ) ./operate -h

Another option for ./operate is -s [poll-time-msecs], and there is also -e [difference] for setting minimum difference (epsilon) for data output (0..65535).

The accelerometer system is based on the system developed for Project Txoom, so the Cerf Notes might be useful if things deviate too far from the script.

  • open q4.oZ-main.mxt
  • open player shell and zoomviewr to see datascrollers

further instructions

- check
    System preferences > Network > Location
    is set to "sensors // no inet"

 - open 'terminal'
- type
      sudo  -s
- enter password
- type
    /usr/libexec/bootpd -D
- connect the sensor to the ceed (black box)
- check ethernet cable is connected to the laptop
- connect the power to the ceed
- wait

 - you can check the connection by typing
 tail -f /var/log/system.log
   and waiting for something like
      bootpd[453]: ACK sent familiar. pktsize 300
   the nu,ber starting with 10.0.0 will be the ip of the ceed
 - type ctrl-c to exit

 - connect to the ceed by typing
     ssh root@
             (the password is rootme)
 - follow the sensor setup instructions from here ... .
 - type
     insmod adxl.o
 - type
     ./operate -h
  (note: this only works when something is listening ie; oz in max)
