+
+This library is really just two files: 'tinyprintf.h' and 'tinyprintf.c'.
+
+They provide a simple and small (+400 loc) printf functionality to
+be used in embedded systems.
+
+I've found them so useful 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 the 'sprintf' family of
+functions ('snprintf', 'sprintf', 'vsnprintf', 'vsprintf').
+
+The formats supported by this implementation are:
+'c' 'd' 'i' 'o' 'p' 'u' '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
+noticeably longer. Likewise with 'PRINTF_LONG_LONG_SUPPORT' for the
+long long specifier, and with 'PRINTF_SIZE_T_SUPPORT' for the size_t
+specifier.
+
+The memory footprint of course depends on the target CPU, compiler and
+compiler options, but a rough guesstimate (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 mileage may vary. By hacking the source code you can
+get rid of some hundred 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 really) 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 interrupts 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' when 'TINYPRINTF_OVERRIDE_LIBC' is set
+(default). Setting it to 0 makes it possible to use them along with
+'stdio.h' printf's in a single source file. When
+'TINYPRINTF_OVERRIDE_LIBC' is set, please note that printf/sprintf 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 function. If it is a
+problem, just give up the macros and use the functions directly, or
+rename them.
+
+It is also possible to avoid defining tfp_printf and/or tfp_sprintf by
+clearing 'TINYPRINTF_DEFINE_TFP_PRINTF' and/or
+'TINYPRINTF_DEFINE_TFP_SPRINTF' to 0. This allows for example to
+export only tfp_format, which is at the core of all the other
+functions.
+
+For further details see source code.
