printf

[Reza Naima]

seems printf works just fine, the arudino people just dont want to tell
you about it?!@

see for more details..

I'll start migrating the code to use it (for the _644 version at least)

That should simplify things a fair bit!

maybe they were trying to keep with the java motif
System.out.println("...");
System.out.print("...");

Serial.println("...");
Serial.print("...");

... now that i think about it, does adding elements in a print
statement work the same as java? like

int stuff;
System.out.println("The integer 'stuff' = " + stuff);
Serial.println("The integer 'stuff' = " + stuff);

One question thought, how much bigger is the firmware with printf? My guess is that it uses up a fair bit of space.

it works the same way C++ handles it, but i don't think it would.  I think they were trying to keep it simple rather than trying to explain to people how printf() worked.

about 2k, which is fine for the 644.

Yeah on the 644 it would be fine, but on the 8k (or was it 16k) original it would have been a big issue! That is most likely why they left it out.
