Hi.
I came across that fputc() is connected with printf() and fgetc is connected with scanf() in cortex-m3 uVision Keil firmware program.
But I can't find exactly how does it connect between them.
Would you please let me know exactly where can I find the connections?
Probably in a materially similar way to how the library code for stdio does on a PC and most C compilers since the dawn of time.
