problem whith SW1 & SW2 on MSP430FG4618

[fatma7886]

Hi,
I work on a MSP430GH4618, I find difficulties with SW1 and SW2. Indeed on the interrupt level “__interrupt void Port1_ISR (void)”, I cannot activate twice the same pushbutton successively for two different functions. For example I want support on S1 to reveal a menu then Second once on S1 to choose options among others in the menu. it carries out the code which corresponds to 2nd supports. Some said that I must return to the main program before the second supports, and others said that I must use a timer. I don’t know how to make.
I am blocked help me please
My code is the following:
//*********************************************************************************
void main(void)
{
volatile unsigned int i;

WDTCTL = WDTPW + WDTHOLD; // Stop WDT
FLL_CTL0 |= XCAP14PF; // Configure load caps

// LFXT1 startup delay
do
{
IFG1 &= ~OFIFG; // Clear OSCFault flag
for (i = 0x47FF; i > 0; i--); // Time for flag to set
}
while (IFG1 & OFIFG); // OSCFault flag still set?
// Configuration du port P1

P1OUT = 0; // All P1.x reset
P1IES = 0x03; // P1.0, P1.1 hi/low edge
P1DIR = 0xFC; // P1.0/1 = input (switches)
P1IE |=BIT0+BIT1;

// LCD_A

LCDACTL = LCDON + LCD4MUX + LCDFREQ_128; // 4mux LCD, ACLK/128
LCDAPCTL0 = 0x7E; // Segments 4-27
P5SEL = 0x1C;
Test_LCD();
__bis_SR_register(LPM3_bits + GIE); // Enter LPM3 w/ interrupt
}
//******************************************************************************
void Test_LCD(void)
{
}
//********************************************************************************
void bagage_1 (void)
{
}
//********************************************************************************
void yes(void)
{
}
//******************************************************************************
// PORT1 interrupt handler : traitement de l'interruption
//******************************************************************************

#pragma vector=PORT1_VECTOR
__interrupt void Port1_ISR (void)
{
volatile unsigned int i, j;

for (i = 10000; i > 0; i--); // Button debounce delay
j = 10000; // Initial delay

// si S1 et !S2
if ((!(P1IN & 0x01))&&(P1IN & 0x02))
{
yes();
if(P1IN & 0x02) baggage_1();
}

}

(If you do not expect P1 to change inside yes(), then) the second if is useless, and you always run either nothing, or yes() followed by baggage_1(). I suppose that the interrupt is working, and initialization its ok
