Example code for Floating-point Twiddle factors Generation:

for (i = 0; i< N/; i++)
{
      NRF_DSP_CFFT_TWIDDLE_COEF[2*i]   = cos(i * 2*PI/(flt32_t)N);
      NRF_DSP_CFFT_TWIDDLE_COEF[2*i+1] = sin(i * 2*PI/(flt32_t)N);
} 

where N = 32, PI = 3.14159265358979

Cos and Sin values are in interleaved fashion
