AW: [Sdcc-user] putchar()

[<MSo...@Mi...>]

Hello Robbo,

there are so many options of what to do with the output of printf (e.g. s=
end
it to one of the serial ports, to a LC-Display with various protocols, to=
 a
parallel printer, to a CRT, to some kind of debugging port) that you have=
 to
write putchar yourself.

Regards, Michael

Betreff: [Sdcc-user] putchar()


Thanks for that, but where do I get putchar() from? do i have to write it
myself? or is it available somewhere?

Thanks for your help, Robbo.
