Clint, I already have the converse of this problem (i.e.,
printing floats (and ints) to a remote console via serial_putchar())
solved. I'm currently working with Fred Martin to make these routines
part of an improved standard IC library. I hadn't thought (yet) about
your problem, reading floats (or ints, for that matter) via
serial_getchar(), but it's clearly doable.
Fred, should I put out my existing cprintf.c library now
and let others start to write the input routines based on my code?
It sounds like the logical long-term solution would be
serialio.c ;low-level serial I/O
conio.c ;my cprintf.c functions, and the converse
;formatted input stuff that Clint is
;asking about
What do you think, Fred?
