m using rhino 4 sr8, which grasshopper version will firefly 3 works? firefly 4 wasnt working withit nor is 3?

Hi Hassan,

I'm a little confused by your question.  Are you saying that Firefly 1.003 or 1.004 are not working on your machine (with Rhino 4 SR8)?  Have you made sure to remove any previous installation files?  Check these locations to make sure any old installations of Firefly have been removed:

C:\Program Files (x86)\Rhinoceros 4.0\Plug-ins\Grasshopper\Components

C:\Users\username\AppData\Roaming\Grasshopper\Libraries

Then, go to www.fireflyexperiments.com and download the latest version (which is 1.005... released last week).  Please follow the installation instructions found on the download page (you have to copy/past two files into the proper directory).  If this is still not working, could you please post a screenshot of the error message or provide a little more information so we can help you debug this problem.

Thanks,

Andy

 

Hi ,

 Thanks for helping me out... i just checked , i have rhino Sr7.  my error is same as this one http://www.fireflyexperiments.com/discussions/post/1232576.

Error something about newer version ... SDK...

Its mentioned over there that firefly will work on 0.7.0053, but this version is asking for SR8. Now the prob is SR8 s askin for Key which i hav lost ... where can i find SR8 or is there any way of running Firefly on my current settings ( SR7 + 0.6.0059)  as this version is supporting geco and rabbit too

Hi Hassan,

Unfortunately... there was a big shift in the core infrastructure between the older builds (0.6.0059) and the newer ones 0.8 and higher.  The move was made to make Firefly compatible with the newer version because all future versions of GH would be using this new Rhino common... so unfortunately, Firefly will not run on older versions of GH.  You could try to download and install an evaluation version of Rhino (http://download.rhino3d.com/rhino/4.0/evaluation/download/).  This is a fully functional version, but it will only allow you to save 25 Rhino files.

HTH,

Andy

Hi,

I bought Arduino UNO just 2 days back. i tried some LEDs it was fine. now when i am upto Stepper motor, i cant afind any logic to feed numbers in grasshopper that does cyclic rotation. i have moved it in Arduino software ( processing type) . now i want to have controlled radian rotation.

 

hassan

can anyone tell me how to run a stepper motor from arduino uno???  its working fine in processing and ardunio sketches

Hi Hassan,

Sorry for not responding sooner.  Jason posted a stepper solution on the Firefly Experiments website.  Check out this discussion and let us know if you need more help:http://www.fireflyexperiments.com/discussions/post/1438445

Hassan,

The generic Serial Write component allows you to send any string you want out to the board... So, you can send the value (1000 0100 0010 0001 ) very easily just using the generic serial write (as in the stepper example).  The only tricky part is you have to parse through the data being sent over the serial port and get it into a format that can be read by the board.  Please look through the stepper example code, as this is taking the data sent over from the board and processing it so it can control the easy driver board.  I'm assuming that since you know exactly how you want the data to be sent to the board, that it shouldn't be too hard.
