I thought I would post this on the list as maybe others have run into this issue. It is emc related although I don't think the problem is. I have an arduino uno that I want to use mainly as a temperature input into emc. (spindle temp) Plus it gives me some extra non realtime inputs and outputs.
I Am playing around with what Jeff Epler had done here http://emergent.unpythonic.net/01198594294 When I plug the arduino into the linux box (10.04) it shows up in dev as ttyACM0. That is the port I put in the arduino-vcp.hal file. The arduion.py file was renamed to arduino and put in the /bin dir and set as executable. I also added myself to the dialout group. Now - when I halrun arduino-vcp.hal I usually have one of 3 outcomes. 1.) the pyvcp pannel opens and everthing seems to work correctly. 10% of the time (estimate) 2.) http://pastebin.com/qVa13VbE (pretty much says it could not open port /dev/ttyACM0 but it is still showing in /dev) 89% of the time 3.) http://pastebin.com/CvEBeCHg (seems to maybe be an issue with the setup of pins within the arduino.py file) 1% of the time Now I have tried this on 2 different computer with the same result. It seems the serial port gets locked some how. I did add some rules in the rules.d directory with the same results.. (like I say - the port shows up in /dev) Seb had me run a trace on the port 'strace hd /dev/ttyACM0' and got http://pastebin.com/SgMjTbpB I am still searching and searching but am coming up with not good solution yet.
