Code for selecting variable speeds to run a treadmill

[Dkumar]

Hi everyone,

So, I need help setting up a code for my treadmill to change speeds automatically with time. For example, is it possible to have a code set up where the treamill initally runs at 1Mph for 20 seconds and then automatically changes to 1.8 Mph for 40 seconds followed by a ramp down of 12 seconds. (total treadmill running time is 72 seconds). I don't have a lot of experience setting up codes so any help would be greatly appreciated.

Thanks,

Devina

Yes it is possible to do what you want -- and it's not even too hard. The best way to approach this is for you to give it a try and post your efforts for comment.

Is this a commercial treadmill with some kind of interface (USB, RS232)? Then what does the manufacture manual tell you?

Or is this a treadmill that you are building? Then what kind of a motor controller have you purchased?

Hi Omar,

So it's a split belt treadill by Bertec. It's basically two belts on a treadmill where each belt can be moved at different speeds. For example, the left belt can be moved at 0.5 m/s and the right at 0.8 m/s with both running together. It has a regular program for controlling speeds but for my lab I need them to change speeds over a period of time automatically.

The manual says a remote control feature is present which can be used by creating a code either in Matlab or Labview.  They have also mentioned that treadmill has a remote.dll (C library) having the minimum functionality for connecting to the Treadmill Control Panel using API. I am basically trying to figure out what information do I need to from the company before I start writing the code.Are there any specific parameters?

Thank you,

Devina

You need a description of the functions in the dll and the.h file if you use the import wizard to create LabVIEW wrappers with the Call Library Function Node. You also need details on the physical connection (RS-232, USB, etc.).

So you already have it connected to your PC with a cable of some type (USB?, RS232? Ethernet?) and can you now control it using the Bertec "regular program" Yes/No? If not you need to get it working FIRST with the Bertec program before you even think about LabVIEW.

Did Bertec give you any LabVIEW code examples? Yes/No?

Did Bertec provide you with any information about that remote.dll. Yes/No

Do you have a copy of the Bertec remote.dll. Yes/No

Do you have a header file from Bertec for the remote.dll? A remote.h file? Yes/No

Did Bertec provide you with any information on the "Treadmill Control Panel" API?
