hello Guys
how can i write this code in mikroC:

if portB.0 = 0 & portB.B1 = 0 & portB.B2 = 0 then do something

Or

if portB.0 = 0 or portB.B1 = 0 or portB.B2 = 0 then do something

& how can i use DO statement to keep in sub function? like

do portc.0 = 1 until portb.b0 = 1

thx for help guys
 

Logical & should looks like this:
Code: 
if (portB.B0 == 0 && portB.B1 == 0 && portB.B2 == 0)
{


}
But the correct way is to check does it equal to 0 or not:
Code: 
if (!portB.B0 && !portB.B1 && !portB.B2)
Because PORTB.B2 == PORTB & (1<<2) which can be 0 or (1<<2)
 

& how can i use DO statement to keep in sub function? like

do portc.0 = 1 until portb.b0 = 1

do
{
<<your code goes here>>
}while(portb.b0 == 0); // or you could use 'while(!portb.b0);'

thx Brian
if im using timer interrupt so how it works with do loop?
is there any priority for the loop or it ignores the interrupt ?
 

if (portB.B0 == 0 || portB.B1 == 0 || portB.B2 == 0) -< OR logic
interrupt is calling interrupt because it interrupts main programm. PIC doesn't support interrupt priorities.

thx for reply but how can i cancel the do loop ? like for emergency stop like:

do {
PORTD = 2;
}
while(PORTB.B1 == 1);
}
i have 3 do loops with three conditions i want to cancel them all when emergency pressed
 

perform 'brake' command
or like this:
Code: 
char cnt = 3;
do {
PORTD = 2;
cnt--;
}
while(PORTB.B1 && cnt);

thx Mr
you mean by changing cnt later it can cancel the do statement ?
