Hello,
I am a university student working on a project that requires simple movement of two servos. I got your board because of its "plug-n-play" abilities. So far everything is working splendidly. Awesome product! :D
I am using bluetooth to communicate, but for my project I am writing other software using MATLAB. I have discovered that MATLAB is able to communicate with other programs if they are Windows "aware". E.g. I can use ActiveX Control to communicate with Excel because they are both Windows aware.
My question is if the ARC software is Windows aware? Or is there any documentation that I could sort through that might show the syntax needed to communicate directly between MATLAB and the board via bluetooth?
I realize this might be outside the scope of questions you usually answer. Any thoughts would be greatly appreciated.
Thanks!
@jschreven You bet! The EZ-SDK DLL is COM Enabled. That means you can include the DLL as a component in your project. You have full access to every public method within the DLL. I keep all methods public, so you have the most control :)
That's great! Thanks for the quick response!
I've got the connection worked out but my communication requests are timing out due to it not finding a terminator. What terminator does it use? E.g. cr/lf or lf.
what do you mean by terminator? a string terminator for what?
It's looking for either a string terminator or a line terminator. If I sent it a command like EZ_B.Servo.GetServoPosition(EZ_B.Servo.ServoPortEnum) I then have to "look-up" the information by reading the return info. It needs to know where the end of the string is.
I apologize if this doesn't make much sense. I might be asking the wrong questions.
Ah i see. That's an interesting question
You are asking it correctly. Because it has been years since i have used COM, i am unsure what the terminator would be. I do know that the response for that particular method is an Integer.
From what i remember, i think it's terminated with a \0 (null). But don't quote me on that.
I would imagine MatLab should take care of it - if it's not, then i'm surprised.
