Hello everyone,
can anyone please tell me about "how can I use <dsk6713_aic23.h> with rxdx"
below source code for connect with labview
target.h make error with dsk6713_aic23.h
and target.h obligatory for connecting with labview
so I can't remove target.h but I need aic23.h
because I want input & output digital sound wave processing
and I usually used function "input_sample()" for input sound but this function included in aic23.h
I really wish to anyone reply for me about this problem
Thanks for reading
