In reply to jmedik. Yup. Been there. The key to solving all of this type of hang is using the debugger.

Thank you very much. I search two days, why dosn’t work it. Reason: the heap was too small

Ah… just found this:

Perhaps it should be listed in “Related Content”?

Yes… memory is very much an issue with printf… actually two people have made commentary. Ill make a article and explain what you are saying… that is a good suggestion

Great book! I remember reading this in college. Also remember banging my head on the desk a lot trying to solve some of the problems.

In reply to Helon_Chan.

void dbg_printf(char *format,…) /// MAX_FORMAT_BUFFER_SIZE)
iWriteNum = MAX_FORMAT_BUFFER_SIZE;

for(i=0;i {
UART_UartPutChar(s_formatBuffer[i]); ///< Uart_function
}
}

If for me, I will give up using this method ( too much memory), I will do like this:

#define DBG_ENABLE (1) ///< Enable DBG_PRINTF
#if DBG_ENABLE
#define DBG_PRINTF(format,…) dbg_printf(format,##__VA_ARGS__)
#else
#define DBG_PRINTF(…)
#endif
#define MAX_FORMAT_BUFFER_SIZE (255)
static uint8_t s_formatBuffer[MAX_FORMAT_BUFFER_SIZE];

void dbg_printf(char *format,…) /// MAX_FORMAT_BUFFER_SIZE)
iWriteNum = MAX_FORMAT_BUFFER_SIZE;

for(i=0;i {
UART_UartPutChar(s_formatBuffer[i]); ///< Uart_fucntion
}
}
