focas fanuc protocol-analysis to python-source
samplescreens on raspberry and android
The python-source is based on protocol analysis. The problem is, that the Fanuc Focas Library does not have proper linux support. The current target platform for protocol-analysis is an EDM-machine with a 160 control and a Robodrill 30i.
"I need more generated protocols (wireshark) from another fanuc-machines."
