scanf take alot of program memory. I need to find an alternative to scanf. I need to read two numbers from seial port, add them and present the result.

As an example, I had the same problem with printf and at last found this code example:

void send_serial(unsigned char *s)
{while(*s != 0x0)
    SBUF=*s;     /*send out the character*/
    while(!TI)   /*wait until sent*/
        { }
    s++;      /*get the next character*/

This code takes much less space.



RE: scanf

why dont you try... inportb()
