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.

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. 

i m uploading standat firmata2_2_for uno_3... just mentioning if there s any prob with that.

Hi claudemit,

At the moment, there is no way (with Firefly) to post data to Pachube.  Its been on my list of something to consider implementing into the tool set, I just didn't know if there was a lot of demand for it.  But, I can take a look at it.  It will likely be a little more complicated as it requires more information to create a feed (than just downloading the current values).  I'll try to take a stab at it, but I don't know when I'll have a time-frame on the next release.  Sorry that I don't have a better solution at the moment, but thank you for your feedback.

Cheers,

Andy

hi andy,

Thanks for your reply.I think we can download the date of some existing buildings from pachube,and then make some simulation and different optimizations in grasshopper or Physical models.It will be funny to show the comparison diagrams on pachube.well,it's just some random thoughts about the "demand".

Hi Giya,

Great videos... Very fun.  I really like the dance floor visualization. Congrats!

Thank you. Btw we were lacking of some features in firefly while developing speedometer based on two proximity sensors and arduino.

We had to rewrite the bang (TogEdge) component and FlipFlop component like they are in vvvv to grasshopper in order to perform needed boolean operations. And grasshopper timers are awful. We need normal flexible counters!

So my "wishlist" for next firefly release is about adding this features. I will appreciate if you implement these things.

Cheers.

HI Giya,

Thanks for the suggestions. I have to admit that I'm not an expert in vvvv and as such I don't exactly know how the TogEdge and FlipFlop components work.  If you could describe how they work (and how they might be applied in a normal setting) I could definitely look into adding this functionality into Firefly.  Also, if possible, I'd like to move this discussion over to the Firefly forum so it can be tracked more closely: http://www.fireflyexperiments.com/discussions/post/1579096?lastPage...

Thanks again for your input.

Cheers,

hi,I meet a problem,when i  send some data to grasshopper with the serial read,the UNO read shows error:solution exception:conversion from string "23.20" to type 'integer' is not valid. How can i solve this problem?

Hi claudemit.  Do you think you could upload a screenshot of your definition?  I'm just curious to know how you setup your definition/arduino sketch to see how I can help troubleshoot your problem.

Cheers,

Andy

hi andy,I use the DPin2 connect a Temperature &Humidity sensor AM2302 with  the library written by  http://www.ladyada.net/learn/sensors/dht.html. if I send the result to firefly meanwhile i use the "UNO read " ,it just show "solution exception:conversion from string "23.20" to type 'integer' is not valid" and not work.I have tried to change the type of the result ,as integer and  float,but it comes out similar error . So i reedit the arduino file like this,it seems to solve my problem.Firefly_UNO_Firmata.pde Please give me some suggestion.
