[LPC1343] Uart send

Hi people,

I am trying to send data to my pc. I already found the example code for the 1343.
It sends the incomming chars back.
I already tried a few things but could not get it working. The only thing the lpc needs to do is send some integer value's to my pc. The communication between pc and lpc already works fine. I am using an zigbee module to send the data.
The lpc does not need to read any incomming data.

Hope someone could help me showing how to send integers to my pc.

What's wrong with printf ?

Ah okey,

Didn't know i can use that. I think i need the uart files to use printf?

No, you just need a function, which uses your hardware to transmit. But I would suggest to use sample uart files.

Printf is just doing the formating for you

You could also write your own function like itoa() to convert an integer to ascii.

 
#include "stdio.h"
...
// Function __write()
//
// Called by bottom level of printf routine within RedLib C library to write
// a character. With the default semihosting stub, this would write the character
// to the debugger console window .
int __write (int iFileHandle, uint8_t *pcBuffer, uint8_t iLength)
{
//this function is writing the printf buffer to uart
 UARTSend(pcBuffer,iLength);
 return iLength;
}
...
 unsigned int dummy;
 dummy =10;
...
 printf("Test: %d\n",dummy);

Thank you :)

I now only see it back into the console not into my terminal.
sorry for my mis understanding but it is not clear for me if i need to include the uart files?
Do i need to init uart? I think i need to tell the lpc what the baud rate is etc.?

Obviously you are using Semihosting Lib. In this mode printf is printing to
your console. Use nohost Lib and printf tries to use __write function.

See:

http://support.code-red-tech.com/CodeRedWiki/SwitchingCLibrary

Of course you have to setup a working uart before (so use uart files or do it in your own way)

Sorry for the double post,

I am now trying to import the files to my own project.
Everything goed well until the debug mode. It say's there are error's but i do not see any red line or something.
When i delete the line printf..... the program works again.

This is my log:

Did you read this?

Your compiler is trying to tell you, that your program is too large for MFlash32 :eek::eek:

So reduce printf size with:

[COLOR=Red]Reducing codesize of printf[/COLOR]

I have read that,

I only need to send int over uart.
I used #define CR_INTEGER_PRINTF but that didn't do the job. Still getting that error.
I can use puts, that does not give any error.

Printf in INTEGER mode needs a few kB. So if your program is >24 kB without printf it could be a problem. Otherwise it should work.
You can also use Optimization :)

I don't even have more then 370 lines of code.
Where can i see how big my program is?

I am using those libs:
#include "LPC13xx.h"
#include "gpio.h"
#include "config.h"
#include "i2c.h"
#include "timer32.h"
#include "type.h"

Or you can use a chip with more memory.:rolleyes:

Are you creating large arrays?
