Hello all,
I am using YAGARTO ver. Newlib-1.18.0 GCC-4.4.2
if i use printf,iprintf.. function in my code the program halts after
"printf".
(if it is deleted no any problem..)
used form in function like that;
printf("something?????..?\n);
the syscalls.c downloaded from the YAGARTO
page(http://www.yagarto.de/download/yagarto/syscalls.c ..)
to check the "_write_r" routine is works or not, i insert the folloeing
code linebelow;
IOSET0 =0x00003C00;// LEDs are connected to the p0.10,p0.11,p0.12, p0.13
*********************************************************************
int _write_r (struct _reent *r, int file, char * ptr, int len)
{
r = r;
file = file;
ptr = ptr;
IOSET0 =0x00003C00;// LEDs are connected to the p0.10,p0.11,p0.12, p0.13
//lcd_write_nibbles('A');
#if 0
int index;
/* For example, output string by UART */
for(index=0; index<len; index++)
{
if (ptr[index] == '\n')
{
uart0Putch('\r');
}
uart0Putch(ptr[index]);
}
#endif
return len;
}
//**********************************************************************
***
The LEDs never light on!this mean that this routine doesnt work.
why?

I can not find any printf in the code... :-/ Perhaps you could post your code. And: what happens when you use puts()? BTW: whats your target processor?
Hello,
Target processor LPC2138. I dont want to use "puts" because i will use
float values in my code. a part of code like this;
//----------------------------
if (msg_tip =='A') { //
i=0;
for (i=0;i<16;i++) ascii7bit[i]=((Read_eeprom(i+20)));
i=0;
}
//..........................................
else if(msg_tip =='B') { //store data
DATA_OUT=2; //write to RAM
printf("V=%0.3f Volt",(temperature )*0.00488281);
//**************************************************************
}
i need to operate analog values in code.
