Macros

#define PRINTF_TARGET_SEMIHOST   1
 Using the semihost support from toolchain, requires no hardware but is the slowest.
 
#define PRINTF_TARGET_UART   2
 Using UART as stdio, this is the default for most of the board.
 
#define PRINTF_TARGET_SWO   3
 Using non-instructive serial wire output (SWO), is the best option since it does not slow down MCU but requires supported from debugger and IDE.
 
#define PRINTF_TARGET_NONE   4
 Using none at all.
