Smoothieware stepper motor signals
-------------------------------------------------------------------------------

This is a capture of Smoothieware stepper signals while running the test.gcode.

Logic analyzer setup
--------------------

The logic analyzer used was an FX2 based device (at 24MHz):

  Probe       Target
  ------------------
  0           ARM ITM trace (irrelevant)
  3           Y axis step
  4           Y axis direction
  5           X axis step
  6           X axis direction


Data
----

Command to decode X axis position:

  sigrok-cli -i smoothieware.sr \
             -P stepper_motor:step=5:dir=6:unit=mm:steps_per_mm=80.0

(though steps_per_mm doesn't currently work in sigrok-cli)
