** General info on the swig-generated wrappers for Comedilib **
|
||||
|
||||
1) Regenerating the wrappers
|
||||
The wrapper were made using swig-1.3.19. Any of the swig-1.3.x seris should work
|
||||
N.B. the default swig on redhat systems is version 1.1. Upgrade to v-1.3.19. It's better!
|
||||
|
||||
run $> swig -python comedi.i
|
||||
|
||||
2) Building the module
|
||||
i) edit the setup.py file so that the include and lib paths are correct for your system
|
||||
ii) run $> python setup.py build
|
||||
|
||||
3) Installing the module
|
||||
i) Manual installation I'm afraid. Copy comedi.py and _comedi.pyd files to somewhere in your PYTHONPATH
|
||||
|
||||
4) Using the module
|
||||
All the comedilib functions are translated directly to python function. The various comedi structs
|
||||
are now available as python classes (e.g. comedi_cmd_struct). The members of each struct are now
|
||||
attributes of the class and can be set and retrieved in the usual way. Comedilib Functions which
|
||||
take a pointer to a comedilib struct as an argument (in C) now, in python, accept the appropriate
|
||||
struct python object.
|
||||
|
||||
For a multichannel acquisition, a C-array containing the channel list, gains and referencing is
|
||||
required. This can be created using a swig-generated helper class: chanlist(n). This creates a C-array
|
||||
of length n and type Unsigned Int. Individual members of the array can be accessed/set using
|
||||
pythons indexing syntax:
|
||||
mylist = chanlist(3) #creates a chanlist array of length 3
|
||||
mylist[0] = 100 #set some values
|
||||
mylist[1] = 200
|
||||
mylist[2] = 300
|
||||
|
||||
The chanlist object can then be passed to a comedi_cmd_struct object, for example. N.B. The
|
||||
chanlist object contains *no* length-checking or other error protection so use with care! Don't
|
||||
try to get/set indexes outside the array bounds.
|
||||
|
||||
All the comedilib macros (e.g. CR_PACK) are now available as python functions.
|
||||
|
||||
check out the example test_comedi.py to clarify the above.
