RE: [avr-gcc-list] printf - low level connection?

[Jim Davis]

Eric,

Im still confused.  I see from the library code that printf calls vfprintf
which in the
end sends characters to stdout via calls to putc.  How do I link this to the
driver code
as shown in the manual?

int uart_putchar(char c)
{
        if (c == '\n')
                uart_putchar('\r');

        loop_until_bit_is_set(UCSRA, UDRE);
                UDR = c;

        return 0;
}

Please dont assume I know anything.  I know this isnt suppose to be too
difficult.

Thanks

Jim
