    of course.

    most of the labs use just 1 motor.

    INSTASPINUNIVERSALGUI can be use to instrument almost any of the MotorWare labs.

    The GUI can be run standalone; meaning you copy/paste your .out into the folder, rename appProgram.out, and launch the GUI.exe

    Alternatively you can import the GUI into CCS and instrument the code as you debug inside CCS (which is what I do).

    Hi Chris

    Tks for your answer

    1,my further question is since the 28069 launchpad is a duel motor driver. If that ok I only connect one motor with one side DRV8301, for example the left one . then, can I run the example projects of the Motorware, anything thing else I should set or pay attention to.

    Is this totally same procedure as using a 28027 Launchpad+8301.

    2, I am evaluating a 28027 Launchpad firstly , and escalating to Proj_Lab11 from Lab2, but always found the motor spinning velocity were not so good and the gMotorVars.Speed_krpm were shown swing a lot (for example the ref speed I set 0.5, it could be swing from 0.45 to 0.53).

    not sure what is the mostly reason and is there any suggestions.

    Best regards

    Eric

    1. Yes, all of the single motor labs (the majority) will run on either J1 or J5 Launchpad connectors of the LAUNCHXL-F28069M. You simply need to define J1 or J5 in the user file

    2. Have you tuned the speed controller? It is not tuned by default. It is set to a general setting which is usually stable for most motors. In the next MotorWare we will include a lab which uses graphing to show you a way to test your controller tuning.

    Hi Chris

    Your help was greatly help to master how to use the solution of launchPad with 8301.

    I finally turn to motorkitscncd69miso_v104 demo solution, which is very suitable to our application ,  but I could not fond the hardware design files of <controlCARD with Piccolo TMS320F28069MPZT> from TI website.

    Could you pls inform me where I could find it.

    Thank you very much

    the HW files for controlCARDS are in controlSUITE

    Hi Chris

    Thank your perfect answer.

    Here, I have successfully spun up the Demo projects from MotorWare actually. It's a pity that I met some depressed results when I try to create my own Instaspin Motion project from the Proj_lab13b (Position Transitions with SpinTAC Move and the motor isTeknic 2310P).

    1.After I tried to create my own project Myproj_lab13b following on the steps of  "e2e.ti.com/.../1159207the disaster happened, I I even  could not resume to run up the motor  again when I repopulated back to the original motorware Projs.

    (1), The code could not correctly check out the DC voltage any more, the value were kept flowing (such as 0.0,9.995698929e-05, 0.0001999735832..etc..),  however my DC input is 29V.----What is the potential reasons , where I need to check on the circuit.

    (2),  The DrvSpi8301Vas shown unknown&Errors throughout all motorware projects, I remembered this was not shown like that。--May it because the item (1)?

    (3),As one of the abnormal scenario proj_lab12a,the  parameters of the Aperk*** were all 0.

    Is that possible the hardware's reasons? however, the example codes still could be compiled and debugged and Run with not Fault report from PCB board.

    2, Is there some latest coaching material related with the procedure of creating customized project from the original Motorware Labs.

    Best regards

    Eric

    I don't know how you tried to customize the projects. if you didn't copy the project settings over directly that is the first place I'd look. The libraries have to be linked in a specific order to work correctly.

    that would be the first place I would look.
