I want to write function for fiq interrupt on LPC2378, Here the program which I have try to run. But it gives error.
void T0isr(void) __fiq //__irq {
T0IR = 1; /* clear interrupt flag */
T0TCR = 0;
Enable_Timer1();
T0TCR = 1;
VICVectAddr=0xff; }
void Timer0_Init(int interval) { /*Load prescaler for 1mSec*/
T0PR=PRESCALER; /** * T0TCR: Timer 0 Control Register * 2: reset counters (both timer and prescaler) **/
T0TCR=2; /* * interrupt and clear when counter=match */
T0MCR=3; /* * interrupt every ms */
T0MR0=interval;
/** * T0TCR: Timer 0 Control Register * 1: enable counting **/
T0TCR=1;
// VICVectAddr4= (unsigned)T0isr; // Set the timer ISR address // VICVectCntl4= 0x00000020 | 4;
VICIntSelect = 0x00000010; VICIntEnable= 0x00000010; }
this program give error
freq.c(184): error: #130: expected a "{"
This program is running for irq but not for fiq....... If anyone know the method of writing a fiq ... please reply to me
The number in parentheses (184) tells you the line number at which the error occurred.
As we don't have your complete file, it's impossible to tell which of the lines you posted is number 184!
Your code is illegible because you didn't pay attention to the clear instructions for posting source code:

Although people might give you the benefit of the doubt for sloppy errors like that, a compiler will not!
A compiler will insist that you write your code exactly in accordance with the language syntax rules - otherwise you will get errors like this one!
When the compiler tells you that it was expecting a '{' (an opening brace), that means that you have broken the syntax rules - eg, by missing a semicolon - and the only way the compiler could make any sense of your text was by assuming that there should have been an opening brace at the position stated.
So you need to look at your code carefully for such mistakes!
If you look at:
www.keil.com/.../armccref_chdfijae.htm
You'll notice that:
__fiq
is not a supported keyword.
Andy, I know error & how to find it. I think you not able to understand my problem, if I am not explain my problem neatly then I am sorry & listen again.
Actually I am not able to find out syntax for defining fiq in Keil, In my program I am commented irq syntax, which running neatly.... But when I am converted it for fiq interrupt, I am not understand some things 1) How to give interrupt handler address? 2) Syntax for fiq. 3) Compiler gives error which is explain already...why? above both problems are not occurred in irq.
If you have any solution please explain me..
Thanks to reply... Ani
