Developers / knx, linuxmce, eib part, ... help?

« on: June 30, 2008, 06:52:24 pm »

EDIT: now working on implementing knx through eibd in linuxmce.
so making a dcedevice to communicate with eibd

old message:


hi

i would like to implement more the knx protocol:
a device on the knx bus is supposed to have a couple adress: one to receive order, one to send back state.

i suppose it is only a matter of translation, but i 'd like to have some help on where in the code is the adress storage coded? and btw, any advise that could help me..

thanx

Developers / EIB read function requirement

« on: June 14, 2008, 02:24:39 pm »

hi, i am trying to implement the read function on the eib programm.

but i don't know what is it supposed to do:
do one know where i could get the base idea of this function? the comments are not.. present, so i don't even know:
is the adress parameter supposed to be a filter?(the adress group of the eibd)? i think so because the overload makes a copy of it, meaning the adress isn't changed. this way of working means read(adress) only pops the last message sent on the bus with the destination of(adress). but i rather be sure of it.
the same way is, if there is no message on bus, how to make the calling program understand it? the function doesn't throw an exception.


i think it's gonna be the same for other functions, so i wold appreciate one to give me tips for getting the way to implement these functions. i could try to get every documentation i can, but i think it would be too long..

thanx

Developers / integrate another daemon to read the bus?

« on: June 12, 2008, 05:19:29 pm »

hi, i have been reported a problem i am supposed to solve:(i am studier,not professional, but trying to get some xp)

i think i am supposed to solve this one:
http://wiki.linuxmce.org/index.php/EIB#Can.27t_read_from_the_bus

according to him, i can have to ways to do so:
1- either modifying what exists already(linked me to http://svn.linuxmce.org/pluto/branches/charon-merge/src/EIB/ ) and make it work
2- or use the http://www.auto.tuwien.ac.at/%7Emkoegler/index.php/bcusdk project to get a fully functional daemon

as anyone else ever got this problem, which is not in the 710 known issues ( http://wiki.linuxmce.org/index.php/KnownIssues_0710 )
may one help me to:
- understand where in the sources is supposed to be the function implemented?(bus reading)
- give me some tips to how to make a wrapper for the daemon?(i mean, what is the interface of the one now?)
- give me some tips they think would be useful for me. i remember i just got my degree from university, so i really am not used with professional programming. but i have much time to learn(it's my goal actually)
