I am trying to get an integer number as input through serial window.To do that I wrote the program below and it didnt work.The problem is with Scanf.Is it correct to give scanf the way that i have given in my program....
when i treid to build i got the following error
void main (void)
/* initialize the serial interface */
PINSEL0 = 0x00050000; /* Enable RxD1 and TxD1 */
U1LCR = 0x83; /* 8 bits, no Parity, 1 Stop bit */
U1DLL = 97; /* 9600 Baud Rate @ 15MHz VPB Clock */
U1LCR = 0x03; /* DLAB = 0 */
printf ("Enter the value of a b c\n");
scanf ("%d %d %d", &a, &b, &c);
"The problem is with Scanf"
What makes you say that?
The error relates to getchar, not scanf.
You need to sort out the problem with getchar first.
the program works well if I use getchar() instead of scanf.
in the ARM development tool manual I read the following The scanf function reads data from the input stream using the getchar routine .
Have you written your own getchar() function?
No i didnt write my getchar functions.
You need to translate the SERIAL.C file using the INTERWORK directive. See:
Even after using #pragma INTERWORK
i am getting the same error !
Please ZIP all project files and send it to email@example.com.
I think there is some minor configuration issue that is hard to figure out in the discussion forum.
sure i will do the same.
There is a mistake in the SERIAL.C. For using scanf, you need to define a _getkey function. Once you rename getchar into _getkey everything will be just fine.
