Heykes allen,
genoten van een laaaaaaaaaaaaaaaange vakantie :-)
Veel meer nieuws kan ik niet vertellen...
De resultaten die ik jullie reeds bezorgde.
Heb wel nog het volgende gevonden via internet, mochten jullie iets met die patchfile zijn laat me dan ééns een mailadres via pb weten dan stuur ik het even door. Maar ik snap er niets van ;-)
'This patch just convert read/write into fread/write, which are buffered and a bit faster... (actually, quite a lot faster) :-) It works, have been tested at the CCC, and allow osmo-tetra to run in real-time on a crappy Atom CPU.
Btw, if you like to run the entire decoding chain in real-time, just do this (assuming that you use the funcube dongle):
cd src/demod/python
mkfifo out.float
mkfifo out.bit
./fcdp-tetra_demod.py -D hw:1,0 -c <offset> -o out.float //(normally the fcdp runs on the second alsa port, change it to the appriopriate one).
../../float-to-bits out.float out.bit
../../tetra-rx out.bit
I'm still not 100% sure about the speech decoder, but i don't have any good sniffer dump with speech traffic to test it, i will let you know in a week or so...
Happy hacking! :-)

P.S. I have a plan to convert the float-to-bits code into a proper GNU Radio module, shouldn't be too difficult, is there any interest into continuing this project?
As I understood Harald is quite busy with other stuff (and rightfully so), but I think that we should move forward. Volunteers? ;-)'

any numbers for that?

yes, I think that is still the plan. I once started trying to do this in python but the GNU Radio bindings only allow to control modules, not really do processing in python.'
