Sorry for the upside down photos. My iPhone for some reason wants to do that today. lol

Thank you for the compliments and also thank you for the help. I'll dig into Describe and see how much I can figure it out.

Well I managed to get the Describe software to interface with the EZB using the Sabertooth's ramping controls and it works perfectly!

Alan, Thank you for the ramping script help because even though I didn't go that route, the script was able to help me understand how ramping works. I needed that base to figure out how to tune the Movement Panel to get the movements correct.

Dave, Thank you for the Describe suggestion! Once I figured it out, the entire process was easy to set up and I didn't have to use the script "work around."

So with this, I will put together a thread on exactly how I was able to get this accomplished so someone else can benefit.

Sooooooo........

Do any of you know how to get a Movement Pad into the mobile app? I have created one with movement buttons but they are not as fluid as the movement pad in easy builder. The movement pad is the virtual joystick I'm looking to have on my iPhone. I've adjusted the ramping in describe to be perfect with the movement pad.

I'm really glad you got the ramping working. You're right, it's such an easy thing to do once you start to understand the software. I'm amazed on how many different adjustments you make on so many different DE devices with this program.

I'm looking forward to seeing your tutorial on setting up the ramping and what ever else you decide to show. I had planned at one time to do one of my own (and still want to one day) but I've been to obsessed with building my B9 to take time away to do it. Besides, there's so much to cover that a guy could write a book trying to show how to do things.

I wish I could help on the Mobile app. Again, I've been busy building to ever make a mobile app. However once the building is completed in a few months I plan to really start playing around with these cool features.

Good luck and happy building.

Great to hear that the ramping from Describe works. As you saw from your searches, this has been talked about a lot, but I didn't know anyone had ever tried setting it in Describe. As I said in the second half of my first post, it is on my todo list to try, but now I know it will work, that is a big relief.

Alan

@Dave - Thank you!

@Alan - I was so wrapped up in scripting that I totally missed your original Describe suggestion. Sorry about that! Anyway, Describe is really simple to play with. I'm a total newbie and even I was able to figure it out. If I can do it, then anyone can. I ordered a Kangaroo x2 to go with it because I think it will make it that much better! Hopefully it will arrive next week.

Thanks again for all your help!

P.S. Describe changes it layout based on what you are trying to control. For example, the ramping controls on the 2x32 are on the motor controls tab whereas the 2x25 has them on the general tab. That threw me for a loop because the Describe manual didn't line up when I selected 2x32 from the drop down menu.

Again, I'm glad it's working out for you. As far as the Kangaroo goes, for it to work your going to have to use a feedback device on your motor shaft like a pot or encoder. This tells the Roo where the motor is and how fast it's moving. The Roo will not work without it. If you end up using the Roo it will add a hole nother layer of complexity and difficulty but you will have precision control.

It is my understanding that it will be able to help me achieve variable speed control over the serial connection. I'm trying to duplicate an RC joystick control where the farther you push the stick the faster the motor will go. Am I misunderstanding the roo?

You're correct. You'll be able to have variable speed. It also corrects itself for load and resistance. Still, be prepared to add some kind of feedback device to your drive motor shaft. The Roo won't work without it. It won't even do a self tune until it detects a feedback device and a motor attached to it with the proper electrical connections made. You also will have to have all the dip switches set properly on both the roo and the sabertooth to match your configuration and how you intend to use it. Once you have all that in place and have completed a successful self tune it works like a dream.

FYI, you can use a RC joystick with the roo. You simply attach the RC receiver to the roo's control input port and set the dips correctly. Here's a cut from the roo's manual (I recommend you download the manual and give it a good read or two):

 In R/C mode, the output position or velocity is
controlled by an incoming R/C signal. This could be
used for cruise control, automatically going the
same speed up or down hills, with varying load and
resistance. It can also be used to create arbitrarily
large R/C servos, proper steering or other
applications. This is also an easy mode to use with
microcontroller boards, because nearly all
microcontroller modules from Basic Stamps to
Arduinos can output an R/C servo formatted signal.
For R/C input, set DIP switch 1 to ON. R/C Input
with velocity mode automatically calibrates to the
input from your transmitter. R/C mode with
position control uses a pulse range from 1000us to 2000us, with the center at 1500us. This can be
calibrated with tune mode 4, or programmed with the DEScribe software.
