DE2-lab4-computer organization exercise help/solution

an you please help me out on the lab_4 exercise in computer organization laboratory exercises. I prefer not to write in assembly, so using C to write the application program for it. Its a DE2 board.

If anyone could please help me out with a solution.

code:

# include<stdio.h>

//define timerr (char *) 0x00011000

define jtag_uart_cnt (char *) 0x00011024

define jtag_uart_data ( char *) 0x00011020

int main(){

char x;

int x2;

while(1){

*jtag_uart_cnt=0xfffff;

if(*jtag_uart_cnt>0){

printf("write data to jtag_uart\n");

scanf("%s",x);

x2=(int)x;

*jtag_uart_data=x2;

printf("sucessfully written to jtag data register\n");

}

}

return 1;

}
