F28027F & BoostXL DRV8301. Solid static movements possible?

Michiel
Are you talking about doing position control or just creating different motion trajectories?

for position control you will need to have a mechanical sensor that can track the rotor position at all speeds, including zero speed. In a robot this is typically done with an encoder (integrated or mounted for each motor). Sometimes you can use hall sensors if less precision is required. If using encoders you would - at a minimum - want to use an MCU with an encoder connection peripheral (eQEP) like F28035 or F28069. You may also consider using InstaSPIN-MOTION (which supports sensored velocity and position control). You could evaluate this using LAUNCHXL-F28069M with the BOOSTXL-DRV8301 you already have.

If the velocity only movements you can achieve with LAUNCHXL-F28027F InstaSPIN-FOC are enough for you and you only need to set-up different motion profiles this is just system code you add to your project. Based on some logic you have different sets of speed and acceleration commands that get set.

Hi Chris,

Thanks for your feedback and insight. The LaunchXL - F28069M definitely looks interesting! I feel kind of bummed out now that I didn't get one of those instead of the LaunchXL - F280F27F. 

I think however that the velocity only movements might just suffice for the time being. But writing that code on my own just way too advanced for me I think, so I might just grab myself a LaunchXL F28069M to work this out in an easier way which is also better suited as a long term solution.

Kind regards,

Michiel
