Description

Library for performing the Park transformation, a mathematical transformation commonly used for BLDC motor control.

Can be used with either standard doubles, or a fixed-point variable type. The fixed-point functions use sine/cosine LUT's (fast), while the double functions use sin() and cos() functions provided by math.h in the standard C library (slow).

Dependencies

The following table lists all of park-transform-cpp's dependencies.

Dependency	Delivery	Usage
<stdio.h>	Standard C library	snprintf()
<math.h>	Standard C library
"FixedPoint.hpp"	/lib/fixed-point-cpp	Fixed point transform functions (faster than doubles/floats especially when system has no floating point unit).

Usage

Coming soon.

See test/ParkTransformTest.cpp for more examples.
