Please note Windows CRLF sequence is not supported,
but a separate CR xor a separate LF works now.
This is a workaround for stupid terminals for debugging purposes,
and it is not necessary for the protocol to work on its own.
It may be removed in the future.
- Move unit/step conversion to modules/axisunit.h
- Unify motion::unitToAxisUnit<> and motion::unitToSteps<>,
making conversion in other modules just as easy as motion.
- Improve the documentation
Introduces:
- config::Unit: base class for physical quantities
- motion::AxisUnit: type-checked steps type
"config/unit.h" defines basic physical quantities, which are not
normally used elsewhere besides config.h.
"modules/axisunit.h" extends the modules::motion namespace with
Axis-aware units, with one type per axis per unit.
P_pos_t defines step positions for the pulley, I_pos_t for the idler,
etc. These are defined through the literar operators which are
similarly named and automatically convert a physical quantity to an
AxisUnit at compile time:
P_pos_t pulley_pos = 10.0_P_mm;
Besides type-checking, AxisUnit are otherwise identical to raw step
counts and are intended to be used along with the updated Motion API.
PlanMove/PlanMoveTo has been extended to support moves using these units
or physical quantities. Again, conversion is performed at compile time.
At least for min/max this will ensure types for both arguments are the
same.
This should be a little bit closer to the <cmath> definition that
simply overloads these functions instead.
This matches PulseGen::Position() and avoids confusion around the term
"current": Position() returns the head position in the queue, not the
"live" axis position.
We have PulseGen::CurPosition() now for this purpose, although we don't
expose it to Motion yet.
CurPosition() returns the live axis position, which in this
implementation is inherently expensive to compute.
This shouldn't be required for the MMU, but it /will/ come in handy to
check for the axis position/s in Motion tests.
