hi all,
i am newbie in dsp,i use ezdsp 28335.
i have few questions.
the first question:
I use ezdsp f28335 floating point to controll AC motor.so i want to use the sine function
defined in "math.h".i have included "the math.h" but the ccs 3.3 says:
......

_Cos D:\\Programme\\MyProjects\\RL_3phase\\Debug\\park_sinus.obj
_Sin D:\\Programme\\MyProjects\\RL_3phase\\Debug\\park_sinus.obj
_park_calc D:\\Programme\\MyProjects\\RL_3phase\\Debug\\RL_3phase.obj
.....
what should i do?should i use sine lookup table?which way is better?
the second question:
like matlab operation, when i delare variable so : float32 : a,x,y,z;
then can i do without IQmath so ??: z = a*x + y; also like in matlab?
the third question:
what does the rts2800_fpu32_eh library do?
thanks!:):):)
