general setup notes for the parts involved in “quartet”
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.
further instructions
- check
System preferences > Network > Location
is set to "sensors // no inet"

- wait
- you can check the connection by typing
tail -f /var/log/system.log
and waiting for something like

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@10.0.0.2
(the password is rootme)
- follow the sensor setup instructions from here ... .
- type
insmod adxl.o

./operate -h 10.0.0.1
