Save arbitrary sensor data to CSV like M956

adambx

Would it at all be feasible to implement saving short bursts of sensor data to CSV similarly to the Accelerometer?
I'm interested in sub-CAN frequency, otherwise i would use a regular loop in a macro.
Many sensors give analog output but 250ms update rate might be a little slow to get meaningful data.

I envision something where there are following inputs:

Sensor number to log
Logging frequency
Duration/number of samples
Filename
(- write XYZ axis position along with the value?)

Just asking for general feasibility as in "maybe 3.7" or "rather 4.0"

Cheers

If you need that in standalone mode, you may get away with daemon.g, a while loop, and a continuous echo command which keeps appending a line to an arbitrary file.

I'd rather use a plugin in SBC mode which subscribes to the main object model that is provided by DSF. The default interval of OM updates in SBC mode is already 250ms and it may be reduced further (e.g. to 100ms) in a future version. It's already possible to reduce the interval using the DCS settings file.

@chrishamm Thanks for the reply.
I was thinking of faster streaming, maybe something along the lines of 100Hz. The added difficulty might be that i'm using CAN Connected boards.

It would be an alternative to making custom boards.
