Thanx
But how can i use interrupts?Can you help?

Some sample code showing usage of ISR would clarify the same. I had tried the Kiel way but it does not work.

Hi,

I don't have any manual for PRO version, but after some test, the following interrupt is working on my demo board:

interrupt
void Timer2_ISR (void)
{
TF2H = 0; // Clear Timer2 inrrupt flag
if(LED1 == 1)
{LED1 = 0;}
else
{LED1 = 1;}
// Change state of LED
}

asm("org 02BH"); //set ROM vector of Timer2
asm("ljmp _Timer2_ISR"); //int service

Best Regards,
Mariusz Lacina

In fact you don't need to use assembler to set up the vector, it can be done like this:

Code:



#define LED1 P10    // port 1 bit 0

interrupt void
Timer2_ISR(void) @ 0x2B // using @ syntax to specify the vector address
{
    TF2H = 0; // Clear Timer2 interrupt flag
    LED1 = !LED1;
}

I was just making these changes myself and each of the processor include files, in my case 8051f0xx.h, has the vectors defined. The line in the previous post can be:

Code:


Timer2_ISR(void) @ TIMER2 // using @ syntax to specify the vector address
