raiden00pl 31ffa6d576 libdsp/lib_observer.c: remove dir argument from speed observers 
We can automatically detect the direction of movement from angle diff
 2022-02-16 03:20:20 +08:00
raiden00pl 01cbe9133e libdsp/lib_observer.c: update some comments 
The angle observer always refer to a motor electrical angle,
while the speed observer can be applied to a motor electrical speed or a motor mechanical speed.
 2022-02-16 03:20:20 +08:00
raiden00pl 26f1be27dd libdsp/lib_observer.c: separate angle observer from speed observer 
They can be used completely independently, so they should'n be coupled.
For example, a sensored motor controller in speed control mode doesn't need an angle estimator.

baggio63446333 917f1a64ad libdsp: Fix compile error with the standard math library 
The libdsp uses M_PI_F and M_PI_2_F which are defined only in the NuttX
math library. Fix an compile error when CONFIG_LIBM is disabled and the
other math library is used.
