DE2-70 RS232 and VGA Question

Try this:

# include <stdio.h>

# include <string.h>

int main ()

{

FILE* fp;

char prompt = 0;

fp = fopen ("/dev/uart1", "r+"); //Open file for reading and writing

//replace 'uart1' with device name you have in sopc builder

if (fp) {

printf("UART Opened Successfully\n");

while (1) {

printf("%c", getc(fp));

}

}

else {

printf("Error: Could not open UART\n");

}

return 0;

}

I have made it in quick time, so not sure if this returns any error, but you can modify it as you like. I have not used but you may want to add fclose(fp) to close UART properly at later stage.
