    Charles,

    You are correct. We expected to have our 2MTR-69M-KIT released by now, so we didn't spend time documentign everythign required to run two motors.  Considering this kit has been delayed we should give you the necessary information to run a two motor system.

    There are air conditioners using 6xF today to run he compressor and fan both using InstaSPIN-FOC at different PWM and controller rates, so it is certainly possible.  It is also challenging to run at higher frequencies and insure you have relevant data for each control loop using a normal interrupt based control system.

    When we release the 2MTR kit we will actually show an example of using our TI-RTOS, which makes life MUCH easier.

    For now, let me do some work on putting together a how-to on adding a 2nd motor to your project.  Give me a day or two....

    Dear Chris,

    Thank you very much! I'll look forward your work.

    I also try to add 2nd motor in one project by myself,it seems not easy to achieve.

    charles,

    Ok, here is some information.  I can't give you the code directly because it has some customer proprietary elements that I can't divulge.  I went through the project and noted all the changes that you would have to make from a normal MotorWare project.

    Let me warn you that this is complicated. There is a large amount of code for you to copy/paste and then make some edits to align the structure of all the objects for two motors.

    It will be VERY helpful once we relase our 2MTR-69M-KIT and there is a solid example project to work from.

    Anyways, I hope this helps you.
