After a long time playing with Yocto, I discover the good news with easy-to-use Lynx 3.0 for raspberrypi, and the bad news as some features of the LabVIEW Real-Time module are not supported on LINX targets, like the shared variables engine (no streams).
But what about bridged, networked and deported software ? So, to make up for it and have fun, I thought about the 0mq library.
Although I'm not sure that's fundamentally necessary, I crossed compile the Zeromq 4.2.0 and the last labview-zmq libraries for arm7 target with that perfect tutorial : https://decibel.ni.com/content/docs/DOC-36921 (thanks thanks thanks M. smithd)
After installed it on my raspberry pi target, it's working with a simple Publisher/Suscriber example in source. (thanks to Amaury Laurent for the code -see his website http://amaury-laurent.fr/, it's fun)
I haven't tested all the functionnality and possibility given by the 0mq technologie, or did stress test, but right now I have datas from my rasp and lattepanda.
I've attached the librairies, the platform.hpp and the labview code (Lv 2014 SP1) for those who think this may be useful to them.
