In embedded debugging, using serial port to print debugging information is a very common means. And these embedded in the functional code of the debug code, in the formal version of the program often need to be removed, in the problem location and need to add in.

The use of macro definitions can easily solve this problem:

In the Config.h file:

/*/#define debug_info 1/    * Set to  ' 1 ' To enable print DEBUG information */ #define dbg_current_types   1/    *  set to ' 1 ' To enable print debug information */#define debug_printf (type,...)         if (((type) & Dbg_current_types))  {xil_printf (__va_args__);}

debug_printf (Debug_info,"This isa DEBUG information!\r\n");
