RampMaker - Stepper Acceleration Ramp Generator
RampMaker is a library that generates motion profiles for stepper motors. It can be used independently, or together with Step/Dir.
The main API for motion profiles is defined by the MotionProfile
trait.
The following implementations of this trait are available:
Flat
: Not for serious use, but might be useful for testing.Trapezoidal
: Constant-acceleration motion profile.
Trinamic have an overview over motion profiles on their website.
Cargo Features
This library works without the standard library (no_std
) by default. This
limits support for f32
/f64
for motion profiles that need to compute a
square root, as this operation is not available in the core library (if
you’re using the default fixed-point types, you’re not affected by this).
If you need full support for f32
/f64
, you have the following options:
- Enable support for the standard library via the
std
feature. This obviously only works, if the standard library is available for your target, and you want to use it. - Enable the
libm
feature. This provides the require square root support via libm.
