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?
you said "I realize that these numbers do not have the complex notation in hexadecimal" What numbers in your screenshot are you talking about? And which compiler version are you using?
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]
