"Yes.  You should be able to send data back to the iPad.  You just need to have the ports correct and the name of the slider, etc.  You should use the OSC Sender for this."

Firefly Now Available for Rhino 5.0

Hi Everyone,

After a long time coming, the complete Firefly toolkit has finally been upgraded for Rhino 5.0 (both 32-bit and 64-bit versions).  This new release includes an updated C_sawapan_media.dll (many thanks to Panagiotis Michalatos!) as well as a new installer!  

The installer should automatically remove any previous versions, and copy all of the core Firefly Grasshopper Assembly files (as well as any needed dependencies) into the roaming Libraries folder on…

Firefly Kinect 0.0004

I have just released an update for the Firefly Kinect (ver. 0.004).  There had been a small bug in the Kinect Video Stream and Kinect Depth Stream components which has now been corrected.  As before, this build uses the Microsoft Kinect SDK 1.5, which means the components will only work in Rhino 5.0.  For best results, I recommend using Rhino 5.0 32-bit version as the Firefly Kinect components also rely on some of the C_sawapan_media.dll functions which has only been compiled for 32-bit…

Hello Andy,

First of all, thank you for your great work.

I am trying to control 30 servos with Arduino Mega 2560 but it seems the servos only twitch as I slide through 0-180 to mega write, and I tried to connect only one servo to different digital pins in several times, the results are the same.

I tested with Uno and all 9 servos worked under the same set up, so I imagined there might be something wrong with the firmatta, and I came across this post in 2011:  http://fireflylabs.squarespace.com/discussions/post/1540044

the Firefly version I'm using is 1.0.0.70 64 bit, does it cover for the "buffer size" and "baud width" issues that you mentioned on the post? 

I am using Rhino 5.0 and the grasshopper version is april-04 2014 build 0.9.0075. the Arduino IDE version is 1.6.5

Thank you for your time.

Hello ,

Andy I sent you a friends request. I am emanuel From the workshop at

TEXFAB.  I am having a issue with the steppers and was wondering if you could take a look at the Grasshopper build that i have used from the library samples.

Thank You

Manny Ferro

Thanks Andy. That cleared up a lot and reinforces what David explained. Had the same thought about handling the high frequency data on Arduino and sending data much less frequency to Grasshopper. Sounds like a challenge that will take some time to figure out.

Hey Andy. Have much enjoyed your gcode definitions in the past and have started using firefly, another great tool. I am trying to do something that sounds like it may have a technical roadblock. I want to read pulse output from an arduino that is running the gcode interpreter GRBL. I use grbl with my diy cnc but I am trying to cobble together a simulator for testing and understanding the firmware and gcode programs I use. The arduino pumps out pulses that are only 5-50 microseconds wide. I think I can set them as big as 255 microseconds wide. I can read the output at 1ms intervals using firefly but obviously drop a lot of information. Do you think there is a way to successfully read those pulses in through firefly?

Hey Andy,

many thanks for your great plug-in.

I am trying to start using Kinect in Grasshopper and I am wondering if you can provide me with some tutorials/hints for beginners?

Many Thanks

Hi Andy,

i've hooked up a dc motor with an h bridge circuit and i have been able to control the rotation and speed so far through Arduino code. Now i wanted to do the same through Firefly, but it keeps working with the Arduino sketch ignoring the current values i am sending through Firefly, shouldn't the Arduino sketch be overwritten? However that was not the case with servos..

Should i reset the Arduino?

Thank you

Hi andy 

I've been trying to work with OSC lately,but unfortunately i was not able to send data from my ipad to grasshopper although I was able to send some data from grasshopper to ipad. all the port numbers and page numbers and stuff seem to be right. i was wondering if you could help me. thnx in advance

Andy,

FYI, I just hooked up a different type of stepper motor (http://robotics.reefat.com/wp-content/uploads/2008/08/PF35T-48L4.pdf) and the speed is much better.  This must be a hardware issue I'll have to look at.  Sorry for the trouble.

Erick

Andy,

I really appreciate the quick response.  My issue here is speed.  I took a look at AccelStepper.h, which mentions that speeds above 1000 steps/sec are unreliable...so just to test it, I tried setting the stepper speed to 1000 on the quadstepper component.  The steppers I'm using are vextas: http://www.interinar.com/vexta-px243m-03aa.html, which have a step angle of .9.  So a speed of 1000 should give me an rps of 2.5, but when I set the quadstepper to a speed of 1000, the actual rps I'm getting is really slow, its more like .2 rps.
