Helping in an External Interrupt!!

#1 Post by aseer » 02 Jun 2010 03:11

I have a project that needs an external interrupt, I tried this code in mikroC PRO for 8051 but it does not work:

void INT0ISR0() org 0x0003 ilevel 0 {
EX0_bit = 0;
P1=0xDC;
Delay_ms(10000);
EX0_bit = 1;
}
void main(){
EX0_bit=1;
do{
}while(1);
}

can anyone help me?

Hi!

Please send me your complete project to my email slavisa.zlatanovic@mikroe.com and I'll try to deduce what's wrong.

It looks like you have forgotten to enable the global interrupt !!!
When all else fails .... Read the fu**ing Manual.!!

Hallo everybody!!

I am using an intel 8031 microcontroller with an external EPROM, everything is going right except the external interrupt. When compiling this extrnal interrupt no error found, but when putting this program on EEPROM it does not work.

I can not find the problem!

Can anybody help me?
