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> + +void init_printf(void* putp, void (*putf)(void*, char)); + +int tfp_printf(const char* fmt, ...); +int 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 + +#endif diff --git a/tmk_core/common/print.h b/tmk_core/common/print.h index 1c77236212..04ca558109 100644 --- a/tmk_core/common/print.h +++ b/tmk_core/common/print.h @@ -72,7 +72,9 @@ extern "C" # elif defined(PROTOCOL_CHIBIOS) /* PROTOCOL_CHIBIOS */ -# include "printf.h" // lib/printf/printf.h +# ifndef TERMINAL_ENABLE +# include "chibios/printf.h" +# endif # ifdef USER_PRINT /* USER_PRINT */ @@ -87,6 +89,7 @@ extern "C" # define uprintf printf # else /* NORMAL PRINT */ + // Create user & normal print defines # define print(s) printf(s) # define println(s) printf(s "\r\n") diff --git a/tmk_core/protocol/chibios/main.c b/tmk_core/protocol/chibios/main.c index 7d32c16ed8..61665eb6f4 100644 --- a/tmk_core/protocol/chibios/main.c +++ b/tmk_core/protocol/chibios/main.c @@ -158,6 +158,9 @@ int main(void) { /* Init USB */ init_usb_driver(&USB_DRIVER); + /* init printf */ + init_printf(NULL, sendchar_pf); + #ifdef MIDI_ENABLE setup_midi(); #endif diff --git a/tmk_core/protocol/chibios/usb_main.c b/tmk_core/protocol/chibios/usb_main.c index 66985b9de8..ecc83d9ecc 100644 --- a/tmk_core/protocol/chibios/usb_main.c +++ b/tmk_core/protocol/chibios/usb_main.c @@ -796,7 +796,10 @@ int8_t sendchar(uint8_t c) { } #endif /* CONSOLE_ENABLE */ -void _putchar(char character) { sendchar(character); } +void sendchar_pf(void *p, char c) { + (void)p; + sendchar((uint8_t)c); +} #ifdef RAW_ENABLE void raw_hid_send(uint8_t *data, uint8_t length) { diff --git a/tmk_core/protocol/chibios/usb_main.h b/tmk_core/protocol/chibios/usb_main.h index 94baf9b35e..17041b4f2f 100644 --- a/tmk_core/protocol/chibios/usb_main.h +++ b/tmk_core/protocol/chibios/usb_main.h @@ -87,4 +87,6 @@ void console_flush_output(void); #endif /* CONSOLE_ENABLE */ +void sendchar_pf(void *p, char c); + #endif /* _USB_MAIN_H_ */ |
