not able to use printf statement in keil uvision 4

And what did you do then?

Did you read any documentation, trying to figure out exactly where printf() should send the output, given that embedded products don't have a default "text console"?

What conclusions did you make, after having realized that printf() needs some support code for actual output of the formatted text?

printf() is not a statement - it is a function.

this is the code for GSM , if i debug i am not able to run in debug mode and it is not displaying message on Serial window

#include <lpc214x.h>
#include <stdio.h>

unsigned int i;

//Serial Port Initialize
void serial_init(void)
{ PINSEL0 = 0x05; /* Enable RxD0 and TxD0 */ U0LCR = 0x83; /* 8 bits, no Parity, 1 Stop bit */ U0DLL = 0x61; /* 9600 Baud Rate @ 15MHz VPB Clock */ U0LCR = 0x03; /* DLAB = 0 */ U0IER = 0x01; /*Enable Interrupt Register */
}

//Delay Routine start here
void delay1(int n)
{ int i; for(i=0;i<n;i++);
}

void delay2(int n)
{ int i; for(i=0;i<n;i++) delay1(1000);
}

//Main program starts here
int main(void)
{ serial_init(); //serial initialization

printf("AT+CMGF=1%c",13); delay2(50); //Text Mode | hex value of 13 is 0x0D (CR ) printf("AT+CMGS=\"9600292363\"%c",13); delay2(50); //Type your mobile number Eg : "9884467058" printf("Hi :-) GSM Modem Test"); delay2(50); //Type text as u want printf("%c",0x1A); delay2(50); //line feed command

while(1);
}

Why not?

What have you done to resolve that issue?

Did you study the documentation carefully on how to use the debugger?

The source code you posted is illegible because you did not pay attention to the instructions for posting source code:

Things will generally not work when you don't follow (or even read) the instructions - so, again, as Per asked, did you study the documentation carefully on how to configure your system to support printf() to your requirements?

Sir/Madam mail me how to configure the printf() function to configure to ARM 7 LPC2148.

i dont have that documentation, how to configure printf statement to support ARM7

Do you mean that Keil have installed an IP filter that is specifically blocking you from reading the documentation online? And no documentation installed in your own machine either? No sample code installed? Nothing?

S SIR I am Unable to open documentation by online

i started to use KEIL uvision 3 now it works sir sir i need some help on coding in ARM using file concept

"I am Unable to open documentation by online"

C'mon now, seriously? Precisely what happens when you click this link?

You seem to be constantly stuck. There are programming courses available. Both generic courses, but Keil also now and then holds courses specifically about their products and how to use them.

The majority of users tends to manage without any extra courses. And the secret is that we spend time reading the documentation and looking at example programs. And, of course, making use of search engines.

So why do we do that? Because we don't want the cost of having a private tutor. And web forums aren't filled with people who are so bored as to be private tutors for free.

Hi Andrew Neil,

I think you're doing everything right.

It works fine for me on a Keil board. I just set AF_CTRL.10 to deselect the SD pins, and set TIMTAK_CTRL1.4 to enable the clock. That gives me full control over the outputs through the EZFR.0 bit.

Well, thank you very much!

:-)

I AM GETTING ERROR LIKE "UART_0_1.c(206): warning: #167-D: argument of type "unsigned char *" is incompatible with parameter of type "const char *"

so how can i solve this problem help me out

Start by trying to figure out the meaning of that const type.
