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. - -regs Kusti, 23.10.2004 -*/ - - -#ifndef __TFP_PRINTF__ -#define __TFP_PRINTF__ - -#include <stdarg.h> - -#ifdef __cplusplus -extern "C" { -#endif - -void init_printf(void* putp,void (*putf) (void*,char)); - -void tfp_printf(const char *fmt, ...); -void tfp_sprintf(char* s,const char *fmt, ...); - -void tfp_format(void* putp,void (*putf) (void*,char),const char *fmt, va_list va); - -#define printf tfp_printf -#define sprintf tfp_sprintf - -#ifdef __cplusplus -}; -#endif - -#endif |
