This is the source code for CASAN.

This directory is structured as follows:

• c-master: code for the master (C++ version)
• py-master: code for the master (Python version, needs Python >= 3.4)
• arduino: code for the slave running on Arduino

Please read the specific README in each subdirectory.

Here are some elements of style for reading the source code:

• all source files are developped with a classical text editor (vi).
• indentation is 4 space wide.
• don't modify the tabulation size in your editor configuration: it should remain the standard 8 column, as with your printer. So, indentation is a combination of tabulations or spaces.
• CASAN C++ master code is documented via Doxygen. To generate the complete documentation, you need doxygen, dot (part of graphviz) and pdflatex: just type make pdf in ./c-master directory.
• CASAN slave code is documented via Doxygen. To generate the complete documentation, you need doxygen, dot (part of graphviz) and pdflatex: just type make pdf in ./arduino/libraries directory.

This section give some quirks to work on Linux.

Use the lsusb command:

# lsusb -d 0403:6001			# vendorId : productId
0403 is hex for FTDI SB-serial
6015 is hex for Digi dev 		# 6001 for Zigduino's

To find all USB-serial devices:

# lsusb -d 0403:

However, the lsusb command does not report device path in /dev

The problem is that USB devices are automatically numbered by the kernel, and this numbering is not stable over time.

See http://hintshop.ludvig.co.nz/show/persistent-names-usb-serial-devices/

Method:

# udevadm info --attribute-walk /dev/ttyUSB0 | grep '{serial}' | head -n1
    ATTRS{serial}=="DA00AFPO"

Create a new file called /etc/udev/rules.d/99-usb-serial.rules and put the following line in there:

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", ATTRS{serial}=="DA00AFPO", SYMLINK+="zig0"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", ATTRS{serial}=="DA00AFPQ", SYMLINK+="zig1"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="digi"

and restart udev:

# service udev restart

Unplug and plug again your devices. You should show them:

# ls -l /dev/zig*
lrwxrwxrwx 1 root root 7 Apr 17 11:54 /dev/zig0 -> ttyUSB0
lrwxrwxrwx 1 root root 7 Apr 17 11:54 /dev/zig1 -> ttyUSB1

Reliable code metrics:

$ find c-master -name "*.[ch]*" | xargs wc -l
$ find c-master -name "*.[ch]*" | xargs cat | tr -d -c ";" | wc -c

$ find arduino/libraries -name "*.[ch]*" | grep -v /boards/ | xargs wc -l
$ find arduino/libraries -name "*.[ch]*" | grep -v /boards/ | xargs cat | tr -d -c ";" | wc -c

Note: sub-directory /boards is not counted since it includes all boards supported by the uracoli library.
