Hi,
I'm trying to get to know the way interrupt service routines are written with msp430-gcc. From code examples found here in the forum I figured out that I have to use #pragma vector = ... , however when I try to modify the simple blink.c example that comes with msp430-gcc I get a compile error.
Here's the code:
---------------------------------------------------------------------
#include <msp430F1611.h>
#pragma vector=TIMERA0_VECTOR
__interrupt void TimerA_ISR(void)
{
//here later some code would go in
}
int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
P1DIR |= 0x01; // Set P1.0 to output direction
for(;;) {
volatile unsigned int i; // volatile to prevent optimization
P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR
i = 10000; // SW Delay
do i--;
while(i != 0);
}
return 0;
}
-----------------------------------------------------------------
The error message I get when compiling this is:
C:/ti/gcc/bin/msp430-elf-gcc -I C:/ti/gcc/bin/../include -mmcu=msp430f1611 -O2 -Wall -g -c -o blink_isr.o blink_isr.c
blink_isr.c:27:0: warning: ignoring #pragma vector [-Wunknown-pragmas]
#pragma vector=TIMERA0_VECTOR
^
blink_isr.c:28:13: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
__interrupt void TimerA_ISR(void)
^
make: *** [blink_isr.o] Error 1
make: Target `all' not remade because of errors.
I know there would have to be more initialisation stuff etc. in the code to get TimerA working but for the time being I would be glad if gcc would compile this file in the first place.
I'm using msp430-gcc without CCS on a Windows machine
What's going wrong here (or more certainly: What am I doing wrong)? Any help is welcome.
Regards,
Jens
