to 250000. Read the FAQ before changing this value.

config STEP_DELAY
int "Step pulse duration (in microseconds)"
depends on CUSTOM_STEP_DELAY
help
Specify the duration of the stepper step pulse time. This
setting applies to all stepper drivers controlled by the
micro-controller. If this value is set to zero (or less) then
the code will "step" and "unstep" in the same C function.
A setting of zero (or less) on 8-bit AVR micro-controllers
results in a minimum step pulse time a little over 2us.
A setting of zero on ARM micro-controllers typically results
in a minimum step pulse time of 20 cpu cycles.
The default for AVR is -1, for all other micro-controllers it
is 2us.
config INITIAL_PINS
string "GPIO pins to set at micro-controller startup"
depends on LOW_LEVEL_OPTIONS
help
One may specify a comma separated list of gpio pins to set
during the micro-controller startup sequence. By default the
pins will be set to output high - preface a pin with a '!'
character to set that pin to output low.
# The HAVE_x options allow boards to disable support for some commands
# if the hardware does not support the feature.
