@frogandtoad Thanks for this suggestion. Having an amped-up Arduino with more memory and a built-in ADC might be the easiest solution. I've ordered...

@jker @will Thanks to you both for taking the time to offer your suggestions. We'll keep working on it and followup here.

@jker @will This is probably getting beyond what I and my student are capable of. Would it be appropriate to suggest that I could send the code for ...

@will Might have to give that a try. Will report back.

@jker The reason to pick up load cell data for each motor step is we need to graph load cell output as a function of steps. We need a good sample r...

@will Right now, we are reading the load cell signal with a 16-bit ADC (ADS1115) which uses I2C. We wanted better resolution than the inherent 10-b...

@jker @will Any suggestions from you two on how to do this? I would be monitoring the load cell in bits not mv?

@jker Thanks for this - and the testing. Nice work! Data wins :) We'll try cutting out the SD card write as a first step. But even if this solves...

We are also saving the step and load data to a SD card which perhaps is a bottle neck as well.

@jker Thank you for this. What you suggest is what we are doing now. Except.... The issue we are running into now is that when we extend the linear...
