I have:
M5stack core s3
M5stack Unit weight-I2C
M5stack Stepmotor Driver Module 13.2 v1.1
10kg load cell
Step motor
trapzodial rod T8x4.

My aim is to build a small tensile test machine and plot displacement vs. load.
Basically:
*calibrate load cell with known weight.
*Tare
*Move load cell by stepper and count step(i.e displacement)
*Poll load cell
*Stop at a set max load
*Save load vs disp in a csv-file
*Reverse motor back to org position

And a graphic on the display showing buttons for calibrate, tare and start.

Best regards, H
