Disabling interrupt in code vision avr
i tried to use interrupt INT0 of atmega16..
i wnt to disable interrupt once the program enters the INTERRUPT SUBROUTINE and enable the interrupt once the ISR gets over. but for the interruot to start for thr first time #asm(“sei”) needs to be given in the main()..
i want to enavle interrut once and then disable it in the ISR..
i have given my code below.
plz help..interrupt [EXT_INT0] void ext_int0_isr(void)
{
#asm(“cli”);
delay_ms(4.752);for(i=0;ilt11;i++)
{
PORTC=PINDampamp0x04;
PORTA=0×00;
delay_us(864);
PORTA=0×01;
delay_us(864);
}
PORTA=0×00;
delay_us(864);
PORTA=0×02;
delay_us(864);
PORTA=0×00;
}void main(void)
{
PORTA=0×00;
DDRA=0xFF;PORTB=0×00;
DDRB=0×00;PORTC=0×00;
DDRC=0xFF;PORTD=0×00;
DDRD=0×00;#asm(“sei”);
while (1)
{
// Place your code here};
}

i tried to decode phillips tv remote IR signal using atmega16 and TSOP 1738(ir reciever) 1st i used interrupts(INT0 - pin16th) to detect the 1st falling edge to syncronise the delays..but after it goes to the interrupt subroutine the falling edges in the input datastream is also considered as interrupt and the subroutine is repeated. suggest me some help to overcome this problem. can i use polling as an alternative to interrupts? if so how? please help. i am using code vision avr as my programming tool.. i am givvin my code: interrupt [EXT_INT0] void ext_int0_isr(void) { #asm("cli"); delay_ms(4.752); for(i=0;ilt11;i++) ...Since I didn't got any answer on my previous question I reopen the item.

I am using L293D motor driver.I have connected 12V to the Vs of this IC. I am getting weird behavior from uc. But when I am connecting the Vs to 5V, I am getting perfect behavior. P.S.

I want to use one switch (SW2) for turn on LEDS connected to PortA an other switch (SW3)to turn on LEDs connected to PortC. SW2 with pin change interrupts and sw3 with external interrupt, but i dont want the microcontroller interrupts when you push the switch, the main program must detect when a switch has been pressed detecting when PCIF1 enable or INTF0 enable. But SW2 dont turn on the LEDS. SW1 works OK. What could be wrong??
