Sysid Acceleration Filtering Removed all data

[Bmongar]

I was able to run earlier in the year but for post season work I was trying to run again and was having some issues. Whenever I try to analyze the data I get “Acceleration Filtering Removed all data”

I am running current released build 22.3.1

Not sure what I did wrong. I have a SDS Mk4 L2 Swerve with falcons. We ran with the wheels blocked straight.

Set up for Meters with a 4 inch wheel 0.3192 units per rotation.

All the tests seemed to run fine but I can’t get the feed forward numbers (or any really) out of the analyzer

Here is the data

The latest release is 2022.4.1. Also, your forward dynamic test data didn’t save. We merged a change for 2022.4.1 that may fix that.

22.4.1 build is failing, and the previous build artifact links don’t work. Is there somewhere else I should download the build from?

Why are you building it yourself? It comes precompiled in the WPILib installer.

Ahh, thanks. I had installed the latest ‘release’ of the whole suite earlier this week (which is a couple of months old) So when you said to get 22.4.1 I google download sysid and it led me to the sysid github. This is good thanks, hopefully I can run tests again tomorrow.

I still get acceleration filtering error. I realize I need to run the test again but how did you bring it up?

Also is my units per rotation correct or should i include my gear ratio ? The old version said not to but this one doesn’t say that.

Those plots came from https://github.com/wpilibsuite/sysid/blob/main/scripts/time_plots.py, which we use for debugging the tool.

Idk.

Thanks, I am just trying to determine is the acceleration filtering problem is my settings or a bug in the previous version.

It’s from the forward dynamic test data never going above the motion threshold, because it’s all zeroed out.
