yes, i use code
| Code: | #include <16F887.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#INT_RB
void rb_isr()
{
output_toggle (PIN_D2) ;
IF (input (PIN_B0) )
{
output_toggle (PIN_D0) ;
}
}
void main()
{
enable_interrupts(INT_RB);// turn on interrupts
enable_interrupts(GLOBAL);
WHILE (TRUE)
{
output_toggle (PIN_D1);
delay_ms (100) ;
}
}

is work, but
| Code: | #include <16F887.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#INT_RB
void rb_isr()
{
output_toggle (PIN_D2) ;
//! IF (input (PIN_B0) )
//! {
//! output_toggle (PIN_D0) ;
//! }
}
void main()
{
enable_interrupts(INT_RB);// turn on interrupts
enable_interrupts(GLOBAL);
WHILE (TRUE)
{
output_toggle (PIN_D1);
delay_ms (100) ;
}
}
|
interrupts loop, never return to main.
What is this error ? code or compilers ?
please help. |

Read the datasheet. You have to read port B once to reset the input mismatch condition, otherwise, the interupt will be executed permanently.
input(PIN_B0) does it. |
