Hello, I have a problem with the following code:
#include <msp430xG43x.h>
void main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
TACTL |= TACLR;
TAR = 0;
P5DIR |= 0x02; // P5.1 output
TACCTL0 = CCIE; // CCR0 interrupt enabled
TACCR0 = 50000;
TACTL = TASSEL_1 + MC_1+TAIE; // ACLK, UP MODE,TIMER A interrupt enabled
while(1)
{
_BIS_SR(LPM0_bits + GIE); // Enter LPM0 w/ interrupt
}
}
// Timer A0 interrupt service routine
#pragma vector=TIMERA0_VECTOR
__interrupt void Timer_A (void)
{
_BIC_SR(LPM3_bits); // Clear LPM3 bits from 0(SR)
P5OUT ^= 0x02; // Toggle P5.1
__delay_cycles(65536);
CCR0 += 50000; // Add Offset to CCR0
}
I don't have any problem when I try to compile it, but at the debugger it never enters the interruption. I have noticed that the TAR never increments its value, so it never reaches TACCR0. I have also tried to use the SMCLK clock, but nothing changes. I don't know how to solve this problem
Thank you in advanced for your help.
