Prototype

short _Q15sinSeries(_Q15 f, short start, short num, _Q15 *buf);

Arguments


`f`	a fixed-point number in Q15 format, which ranges from 0 to (2³¹-1). The valid range of values for this argument is from -16384 to 16384. The argument represents the Normalizing frequency.
`start`	a fixed-point number in Q16 format, which ranges from 0 to (2³¹-1). The valid range of values for this argument is from 1 to 32767. This argument represents the Starting Sample number in the Sine Series.
`num`	a fixed-point number in Q16 format, which ranges from 0 to (2³¹-1). The valid range of values for this argument is from 1 to 32767. This argument represents the Number of Sine Samples the function is called to generate. Note: `num` should not be more than 16383 for dsPIC and 32767 for PIC devices.
`buf`	a pointer to the buffer where the generated sine samples would get copied into.

Return Value

This function returns num, the number of generated sine samples.
