HI,I Want use gun in keil.now,Can't output debug log to uart.I
have implement fputc like this:
int fputc(int ch, FILE *f)
{ if (s_debugInit) { UART_SendData(DEBUG_UART, ch); } return ch;
} but when I call printf,don't call fputc function.what's
worry?Thanks for your help!
I have add syscalls.c in my keil project.
syscalls.c
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include &
