RE: [avr-gcc-list] printf'ing a string in program memory

[Tom Harris]

Joerg,

What character were you thinking of using for a string in Flash? I prefer
"%z". I am very close to running out of Flash, if I do the first function to
go will be vprintf as it does far more than I need, even in the minimum
version. I will write my own with just the formatting functionality that I
need, and I will include Flash strings as well, so it may as well be
compatible. Or if we upgrade to a larger part I shall modify the printf
source.

Not yet there.  It's on the list of things I always intented to do, but
never actually did so far.
