High Priority PIC18 Interrupts

[sigmaorion]

Hi all,

My code is something like I describe below:

----------------------------------
----------------------------------
----------------------------------
#include <18F4550.h>
#device high_ints = true

#FUSES ...
.....
.....
#FUSES ...

#use delay(clock=48000000)
#use rtos(timer=0,minor_cycle=20ms)

#INT_TIMER1 HIGH //<-- error line here
void sampletimer_int() {
...........................
interrupt code here
...........................
}

void main() {
...........................
main program here
...........................
}
----------------------------------
----------------------------------
----------------------------------

When I try to compile it I get "Error 7 "test.c" Line 19(12,17): Invalid Pre-Processor directive.
The indicated line is "#INT_TIMER1 HIGH" and the errors disappears if I delete the "HIGH" directive. I really need this interrupt to be of high priority.

Is there anything I'm doing wrong? The compiler version I use is 4.104.

Thanks in advance.
Regards...

Try this program. It compiles OK for me with vs. 4.104. It doesn't give
any errors.

Separately, if you are also using the INT_EXT interrupt, you should be aware that this will always be a high priority interrupt, if high priority interrupts are enabled. Can catch the unwary.
I'm sure it's the spaces causing the problem.

Hi guys, thank you very much for your responses.

Finally I found the problem was I had defined "define HIGH TRUE" because I wanted to use the keyword "HIGH" for pin states. Of course it was causing troubles later in the code when I tried to use the keyword HIGH to define the interrupt as high priority.

The "stupid" code:
#define HIGH TRUE
#INT_TIMER1 HIGH

Is not a good idea!!! I passed my eyes over that mistake without seeing it, hehe.

Thanks again everyone!
