I have a bit of a problem right now..
I have 2 mega32 with a serial connection between..
One uC is the master, the other is a display driver for my 32x16 LED display...
but I can't figure out if it would be smartest to use printf or just write my own serial function with buffer..
The data I'm gonna send from uC to driver is:
a control char followed by 2 to 64 data bytes
a control char followed by a string of text with variable length.
I've never used printf before.. so right now it sound kinda scary... how much space will it use ? how do I use it?
