[SOLVED] problem: error on compiling _ LPC1768+CMSIS+ RIT Unit

[enekas]

Hello

I wanna use RIT by CMSIS for LPC1768 ( Compiler : Keil )
my code:

#include "LPC17xx.H"  

#include "system_LPC17xx.h"  
#include "lpc17xx_clkpwr.h"
#include "lpc17xx_rit.h"

unsigned int i=0;

void RIT_IRQHandler(void)
{	i++;
	if(i%2==0)
	LPC_GPIO2->FIOSET=0X01;
	else
	LPC_GPIO2->FIOCLR=0X01;
	RIT_GetIntStatus(LPC_RIT);
}

int main(void)
{
//	NVIC_SetVTOR(0X2000);
	LPC_GPIO2->FIODIR=0X03;
	RIT_Init(LPC_RIT);
	RIT_TimerConfig(LPC_RIT,100);
	RIT_Cmd(LPC_RIT,ENABLE);
	NVIC_EnableIRQ(RIT_IRQn);

 	while(1);
}

Compiler error:

Build target 'Target 1'

rit.axf: Error: L6218E: Undefined symbol check_failed (referred from lpc17xx_rit.o).
Target not created

I solve some errors by changing some headers , but I can't settle this one
any suggestion?

Tanx.

Is your header files in the include folders or project folder? i.e., where the header files are present or is it in a different directory? If the library files arenot in project directory then you have to use #include <...> instead of #include "..."

Tanx , because of your quick reply ...
yes, all header files are in project folder. then i used #include" ... "

 

[jayanth.devarayanadurga]

It is telling L6218E is undefined. What is L6218E in LPC terminology? I don't use LPC controllers. L6218E definition is missing in some file. I see that the file lpc17xx_rit.c is not included anywhere in the project. I think this file is needed to generate lpc17xx_rit.o object file properly. Include this file and compile. See if that works.

Also put the below files in the project folder

lpc17xx_libcfg.h
lpc17xx_libcfg_default.h

Tanx jayanth.devarayanadurga ...
Some headers (... .c) included by IDE , it's a different method & will be done without use #include"..."
It seems that's because of " lpc17xx_libcfg_default.c "
We don't have any error on " lpc17xx_rit.o " now ! , Tanx ..., you're right
But then some error occurred, i solved and everything is fine now.

Thank you very much
Good luck my friend
