I have problem when use printf function in Keil uvision when select
Realview Compiler ( Not Keil CARM Compiler ) . it can compile ( not
have error ) but not have any response send to serial port.
system = LPC2103 + 12.000MHz + RealView MDK-ARM 3.03q Evaluation
#include
#include
void init_serial0 (void);
int main(void)
{
init_serial0(); printf("Hello LPC2103 TEST UART-0\n");
while(1);
}
void init_serial0 (void)
{ PINSEL0 |= 0x00000005; U0LCR = 0x83; U0DLL = 97; U0LCR &= 0x7F;
}
But when i write sendchar , sendstr and sendhex functions same
MCB2103 Blink Sample code. it work !!

printf function with Realview Compiler

As far as I remember the RealView compiler uses its own libraries for
standard (IO) functions. If you want to use your own instead you have
to specify a comand line option (something like --no-std-libs, but I
could be mixing up gcc options here).
I do not have the RealView stuff at home so I cannot help you with the
specific options but check the manuals on linking and usage of
libraries, you'll find the solution in there.
Good luck,
Rob

Look at C:\Keil\ARM\RV30\Examples\Hello and you will see
that "serial.c" is included in the project. Copy this serial.c to
your project folder and edit as needed to be sure that it is setup
for the serial port you are using and you should be fine, I think.

I'm guessing you may have switched over from CARM to RealView, in which
case
you'll need to change a few things with your serial.
You'll need to write your own versions of sendchar, getkey and timeval if
you want to use them (but by the sounds of it you already have). Aside from
that you'll simply need some wrapper functions as described below and it
should all work.
(contents of file retarget.c to be added to your project)
#include
#include
#include
#pragma import(__use_no_semihosting_swi)
extern int sendchar(int ch); /* in Serial.c */
extern int getkey(void); /* in Serial.c */
extern long timeval; /* in Time.c */
struct __FILE { int handle; /* Add whatever you need here */ };
FILE __stdout;
FILE __stdin;
int fputc(int ch, FILE *f) {
return (sendchar(ch));
}
int fgetc(FILE *f) {
return (sendchar(getkey()));
}
int ferror(FILE *f) {
/* Your implementation of ferror */
return EOF;
}
void _ttywrch(int ch) {
sendchar (ch);
}
void _sys_exit(int return_code) {
while (1); /* endless loop */
}

Timeval is simply the representation of time in terms of a structured way of
recording it. I shouldn't worry about it too much as it appears you aren't
using it anyway. If you are simply do a search for the time.h header file
and timeval struct. Glad to have helped get your serial up and running again
:)
