MSP430 LaunchPad with G2553 --- P2.6 interrupt does not work

[uka1024]

Hi !

First I used the example delivered with the Launchpad stuff and got
the P1.4 interrupt running ok (resulting in changes of red LED state).

Then I tried the same with P2.0 and P2.4 - they are working ok, too.

Then, trying with input P2.6 the interrupt does not work ! This is also
the XIN-pin on the board, but i don't have the XTAL soldered on it....

The datasheet for the G2553 doesn't give me a hint. Please, help ...


With thanks in advance & best regards, Uli

Hello,

Please find the below code for P2.6 Interrupt Driven.

[syntax=c]#include<msp430g2553.h>
void main(void)
{
WDTCTL=WDTPW+WDTHOLD;
P2DIR |= BIT6;
P2SEL &= ~BIT6;
P1DIR &= ~BIT3;
P1SEL &= ~BIT3;
P1IN |= BIT3;
P1REN |= BIT3;
P1IE |= BIT3;
P1IFG &= ~BIT3;
_BIS_SR(GIE);
}
#pragma vector=PORT1_VECTOR
__interrupt void port1(void)
{
P1IFG &= ~BIT3;
P2OUT^=BIT6;
}[/syntax]

Thank You,
