----------------------------------------------------------------------
This library is realy just two files: 'printf.h' and 'printf.c'.
They provide a simple and small (+200 loc) printf functionality to
be used in embedded systems.
I've found them so usefull in debugging that I do not bother with a
debugger at all.
They are distributed in source form, so to use them, just compile them
into your project.
Two printf variants are provided: printf and sprintf.
The formats supported by this implementation are: 'd' 'u' 'c' 's' 'x' 'X'.
Zero padding and field width are also supported.
If the library is compiled with 'PRINTF_SUPPORT_LONG' defined then the
long specifier is also
supported. Note that this will pull in some long math routines (pun intended!)
and thus make your executable noticably longer.
The memory foot print of course depends on the target cpu, compiler and
compiler options, but a rough guestimate (based on a H8S target) is about
1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack space.
Not too bad. Your milage may vary. By hacking the source code you can
get rid of some hunred bytes, I'm sure, but personally I feel the balance of
functionality and flexibility versus code size is close to optimal for
many embedded systems.
To use the printf you need to supply your own character output function,
something like :
void putc ( void* p, char c)
{
while (!SERIAL_PORT_EMPTY) ;
SERIAL_PORT_TX_REGISTER = c;
}
Before you can call printf you need to initialize it to use your
character output function with something like:
init_printf(NULL,putc);
Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc',
the NULL (or any pointer) you pass into the 'init_printf' will eventually be
passed to your 'putc' routine. This allows you to pass some storage space (or
anything realy) to the character output function, if necessary.
This is not often needed but it was implemented like that because it made
implementing the sprintf function so neat (look at the source code).
The code is re-entrant, except for the 'init_printf' function, so it
is safe to call it from interupts too, although this may result in mixed output.
If you rely on re-entrancy, take care that your 'putc' function is re-entrant!
The printf and sprintf functions are actually macros that translate to
'tfp_printf' and 'tfp_sprintf'. This makes it possible
to use them along with 'stdio.h' printf's in a single source file.
You just need to undef the names before you include the 'stdio.h'.
Note that these are not function like macros, so if you have variables
or struct members with these names, things will explode in your face.
Without variadic macros this is the best we can do to wrap these
fucnction. If it is a problem just give up the macros and use the
functions directly or rename them.
For further details see source code.
