debug_scanf() not working?

giacomopetrini — Thu, 12 Mar 2015 15:24:19 GMT

Hello,

in a project, created with KDS 2.0.0, KSDK 1.1.0 and PE, I'm trying to create some user interaction with the console.

I added the fsl_debug_console component in PE.

I can output messages using debug_printf() and read 1 character using debug_getchar().

Now in fsl_debug_console.c there is the debug_scanf() funtion, that I expect to work like the classic scanf().

But it seems that it doesn't:

 uint16_t choice;  debug_printf("\nSet Year (last 2 digit): ");  choice = debug_scanf("%d",&choice);  debug_printf("%d\n",choice);

The input is "15\n", so I expect that the debug_printf() outputs "15\n", but the output is "1\n".

Am I doing something wrong?

Thanks, regards Giacomo

Hello giacomopetrini,

the bad thing is, that you assign debug_scanf("%d",&choice) to choice.

You must do it by this way:

uint16_t choice;

debug_printf("\nSet Year (last 2 digit): ");

debug_scanf("%d",&choice);

debug_printf("%d\n",choice);

Best Regards,

Iva
