2 Motors using InstaSPIN-MOTION

Other Parts Discussed in Thread: MOTORWARE

I'm interested in running two BLDC motors using the F28069M chip, running InstaSPIN MOTION with speed control.

I've got the FOC version working with 2 motors currently from this community using the Launchpad and two BOOSTXL-8301 Rev. B daughter boards, that worked without too much trouble.

My application is to send USB speed commands to the two motors and have them running at different speeds and possibly directions.

1. Foresee any issues with resources or pins with doing that?

2. Any tips or advise?

We apologize for letting this one slip through the cracks. Were you able to spin two motors using external comms commands for speed reference? I'm not sure if we had the 2 motor example in Motorware in 11/2015, but the most recent version of Motorware should have a good example on how to perform this. There should be no issue with CPU resource, usage or pin out for an application like you describe.

No problem. I did the motors to both spin using the examples. When I posted this I was waiting a couple months for the reply. Sorry about snarky response, must have set off the "rude sarcasm" detectors on the website - the response was pretty quick!
