Printf is sufficiently general-purpose that for most small embedded
apps it is overkill and uses way too much memory for the parts of it
you're likely to need, and you'd usually be a lot better off using
your own code  to provide just  the functions you need.=20

e.g. for strings
void dispstring(char *sptr)
{ do  dispchar(*sptr++);   while (*sptr !=3D 0x00); }
numerics and fixed-point decomals are also pretty straightforward and
can be coded with a lot less code than printf. Again you can limit the
numeric code to just the functionality you need.=20
