doccuments the various out put strings.
The default output format is CSV, here there is a reduced output to be used by the main client/server
If the command "JSON 1" is issued to the serial input the output switches to json, this is for debugging
there is much more data available in this mode for hardware testing, adjusting variables and monitoring
LPS.cpp and LPS.h
This is a modified version of the LM25 library modified to address the LM25 on the main board on bus ONE
bmp085.cpp
This handles the adafruit BMP085 barrometer breakout. Its not used in the standard hardware configuration,
however ot is possible to plug this breakout on the main board to replace the LM25
cosmicpi-arduino.cc
This is the main firmware. The firmware runs in the CSV simple mode by default. However it can also run in
the JSON mode that accepts commands to change settings, outputs debug and monitoring information. This mode
is chosen if the test program "pi-client.py" is run. This permits advanced interaction with the firmware for
people who want to investigate whats going on under the hood.
cosmicpi-arduino.ino
This is just a symbolic link to cosmicpi-arduino.cc for the Arduino IDE. If you point the Arduino IDE at
this link you can compile and upload the firmware accross USB
pi-client.py
This is an interactive test program for interacting with the JSON mode of the firmware. It talks to the
cosmicpi accross a USB port. To see the options type "./pi-client --help". To launch it you must specify
which USB port to use, typically in Ubuntu linux it would be /dev/ttyACM0 or /dev/ttyACM1. To determin
the port issue the command "ls /dev/tty*" before and after plugging in the cosmicpi to the USB. The test
program requires write access to the /dev node, and depending on your system configuration you may need
to run with sudo privaledges. Once the test program is running type the ">" character to get a command
prompt, the type "h" for help.
example:
sudo ./pi-client -u /dev/ttyACM0
sudo ./pi-client -u /dev/ttyACM0 -i 31.194.73.171 -p 15443-o .
pi-server.py
The client pi-client.py can be configured to send events and other information such as siesmic events,
weather station events, changes in magnetic field, and cosmic ray events to the server through UDP
TCP/IP datagrams to the server. This can be useful for test involving multiple cosmicpi devices. These
devices may be local or at remote locations. The server is able to corrolate and log data for futher
analysis. See example above for specifying an ip address and port.
example:
./pi-client.py -p 15443
