Hello Tom, Of course, how could I forget? I had to modify your code a bit to get to work, however:
const float *in = (const float *) &((const float*)input_items[0])[history()-1]; It just needed a type cast in there. My code works now. The suggestion about gr_quadrature_demod_cf is very helpful; this will be a good reference moving forward on this project.
