Out of the box support for AS5048

Are there any features that you would like to add to the VESC?

Out of the box support for AS5048

Postby dpetrillo » 26 Jan 2016, 16:23

I'd like to see support for the AS5048 encoder added to the config tool.

http://ams.com/eng/Products/Position-Se ... rs/AS5048A

It's a popular choice for Gimbal motors and could be useful for robotics applications.

I have actually ordered an AS5047 and a small PCB for it is on its way, so I'm going to implement support for that soon. I also think that these sensors are nice as they are easy to mount and don't require running the motor to an index pulse first.

What AS5047 do you mean? There is the AS5047P and the AS5047D. The datasheet says that the P version is for "High speed application" so I think you will use the P.
Is the AS5048 not fast enough or why going with the AS5048? Think the AS5048 is better available than the AS5047.

My as5048 reads position between 180 and 360 really well but not from 0-180 degrees.
I tried on two vesc's but same. The data coming from AS5047 is clean. When I rotate motor by hand 1 full rotation the position ends up at exact position in BLDC tool, it just skips from 360 to 180 and then up again.
As a result using position control under 180 does not work. between 180 and 360 works perfect.
What am I doing wrong?

Someone using AS5048 and trying to do position control that has the same problem / has a solution?
