I am trying to make an FFT algorithm on a stm32f407ve development board. For this I first tried the program in matlab and it worked, I passed the syntax to keil and it did not work. When using the library I have a problem because it does not recognize the macros for the notation of the "_I_" however I found an alternative way by declaring the i as the root of -1 as complex and I could already use the complex numbers obtaining its real and imaginary part with the functions of the libraries (I tried giving times to a led to see if it recognized it number). But when using the debugger I realize that these numbers do not have the complex notation in hexadecimal. What can it be?
that is, in the debugger window I remember that I saw in a publication that showed a+b*i being a and b hexadecimal .Of the number X2 [1]
