xilinx inbyte

Inbyte is a C function that you receives a char (a byte) from a generic port. To do this, you will need to develop a UART module (RS232) in your Spartan, and develop a computer software to send data. Or you can use a hardware, for example, a GPIO and conect direct to your module, and now using inbyte. Copied that?

Re: using inbyte

im using c langauge switch case in the XPS to enable the board to respond back to the pc. for e.g when i type "a" in the hyperterminal, i want it to return a "b" in the pc. however it appear my "a" into another character. but it still will reply a "b". i only can once after it has respond. i dont noe where is the error. below is the code tt i've tried:

int main (void) {

int inchar;
xil_printf(">");
inchar = inbyte();

xil_printf("%c\n\r");
switch(inchar){
case 'a':
xil_printf("b\n\r");
return(0);

case 'b':
xil_printf("c\n\r");
return(0);
break;
}

}

using inbyte

In this line, the argument is missing: xil_printf("%c\n\r");
You probably meant this: xil_printf("%c\n\r", inchar);

A good compiler should warn you about that problem. Try enabling all of its warning messages.
