I'm trying to retrieve data from a tag heuer timing system through rs 232. Firefly ports available says com ports 1 and 3 are available. Is one of those two the rs 232 9 pin? Thanks for your help.
levator over the automobile, complex issues are at play in concentrating population and built infrastructure in contemporary high-rise cities. How do you meet the challenges of system design for high quality compact urban environments?
The Smartgeometry Workshop is a unique creative cauldron attracting attendees from across the world of academia, professional practice and industry. The workshop is open to 100 applicants who come together for four intensive days of design and collaboration.
More Info and to Apply
The application deadline to attend the sg2014 Workshop has been extended to June 1st, 2014 at midnight PST. Reviews and early notifications will proceed for those who have already applied.

WORKSHOP CLUSTERS
The sg2014 Workshop will be organised around Clusters. Clusters are hubs of expertise. They comprise of people, knowledge, tools, materials and machines. The Clusters provide a focus for workshop participants working together within a common framework.
Clusters provide a forum for the exchange of ideas, processes and techniques and act as a catalyst for design resolution. The sg2014 Workshop is made up of ten Clusters that respond in diverse ways to the challenge Urban Compaction.

CONFERENCE
After four intense days of innovative work, the 2-day sgConference offers an opportunity for critical reflection on what has been accomplished in the Workshop and in the global design arena. It will be an opportunity to open debates, pose questions, challenge orthodoxies, and propose new ideas.
The sgConference features invited keynote speakers showcasing major projects and research from around the globe, mixed with panel sessions for open debate. The end of the first day will include reports and highlights from the Workshop, giving an opportunity to view work created during the previous four days of intensive collaboration, design and development, followed by an exhibition of the work.

mputer... so 1 seems strange. Also, the serial port is closed, so you wont be able to control your steppers until you open the port. Lastly, the Stepper Motor component also has to have the Start toggle set to true before actually sending values to the board. Hopefully that helps.…
should not be open).
3. All releases of Rhino 5, Arduino, GH, and FF are the latest as of May 21st.
I Boolean toggled the port open, but I can't seem to get any output to display from the UnoRead component. I was hoping to see values from any of the analog inputs (APin5 depicted) connected as info gets sent back and forth between the Arduino and my comp. I'm getting simultaneous "Hooray" and "Whoops" messages, and I can't pinpoint why. See attached JPG.
Does it have to do with the fact that I have a list of COM ports? Even though I know COM 3 is the correct one as defined in the IDE, do I need to re-declare it in Grasshopper as well? Does the {0} shown impact this output?
Any direction is appreciated.
Thanks - JFig

ying specifically the one port you want to talk to. My guess is that you're Arduino is actually connected to Port 3 (not 1 or 2). Since the Ports Available is returning a list (this would also be the case inside the Arduino IDE BTW)... there are a couple of options you can try. You could use a List Item and retrieve the specific COM port number you're looking for (item 2 in this case). Or you could simply type the number 3 in a text panel and connect that to the Open Port component. You could also right-click on the Port input and set the integer manually that way as well. Any of these will work. But, its important that you're only opening up a single port and not a list of ports. Make sure you also specify the same port on the Uno Read component as well. This should fix your problem (although please let me know if you encounter other issues).

o 'curves'. In the script, it still expects 'x'. I have to add another input before it will refresh and call the input 'curves'.
2/ Upon loading gh, it gives the following error message. This has only happened since upgrading from version 9.0075 to 9.0076
Priority: PreLoad
{
Method not found: 'System.String Grasshopper.Kernel.GH_ComponentServer.CopyFileToRoamingFolder(System.String, Boolean)'.
MissingMethodException
}
3/ I also posted a few bugs here a while ago, just wanted to bump that up:

that data via serial to an external program to play as MIDI.
The problem is, I am using a third-party (Spikenzie Labs) serial-to-midi converter that cannot speak to the COM port while Firefly also does. Bear with me, as I am just starting to figure this out, but I imagine the following possibilities:
1. Hardwire an actual MIDI-out into my prototype and code it so that the signal is sent this way. Get a MIDI-to-USB cable and go into a different COM port.
2. Set up a virtual serial port? No idea if this is a thing.
3. Internalize the serial-to-midi conversion/TX to my Grasshopper/Firefly setup. I don't really know what this entails.
Any thoughts?Thanks as always for all of your digital trailblazing...
