int Factorial()
{
 
int i;
u32 fact=1;
u32 N, j;
while (1) {
print("Enter the number \n\r");
N = inbyte();
j = N - 0x30;
for (i=1; i<=j; i++)
{
fact = fact*i;
xil_printf("[sw] Factorial = %d\r\n", fact);
}
return fact;
}
}


Any suggestion. please welcome.

Similar to printf(), a C compiler has library functions to read formatted decimal input, e.g. scanf().
 

Thanks for your response. I cant understand please explain me in detail. How can i enter number above 9 in the terminal.

I am using XSDK and tera Terminal.
 

Since your input will be in decimal, #2 tells you to try out the alternative function scanf() instead of inbyte(). Else you need to explore what other functions are supported by the Xilinx compiler.

XUartLite_RecvByte and XUartLite_SendByte Not working_XSDK

Hi, I am fresher to VIVADO and XSDK, so i have taken simple Task "factorial" program to run in hyper terminal using XSDK. I need to input the number to terminal, so i have used "XUartLite_RecvByte" and "XUartLite_SendByte" function for inputting the Number to Factorial program. Please anyone sort out my problem

Its showing wrong result.

Source code


Code: 
int main()
{
    int i;
    uint32_t fact=1;
    u8 N;
init_platform();
//XFact Xfactorial;
//XFact  *xfactptr=&Xfactorial;
//XFact_Initialize(xfactptr,XPAR_FACT_0_DEVICE_ID);
print("\r\n----\r\nFactorial Function\n\r");

N= XUartLite_RecvByte(0x40600000);
         XUartLite_SendByte(0x40600000,N);
         xil_printf("\r\n\r");

 for(i=1;i<=N;i++)
        {
    fact =fact*i;
    XUartLite_SendByte(0x40600000,fact);
    xil_printf("Factorial is %d\r\n", fact);
        }
//XUartLite_SendByte(0x40600000,fact);
    //xil_printf("\n ");
cleanup_platform();
return 0;
}
