I am trying a very simple code to generate a PWM using the CCR1 and CCR2 with MSP432.. Here is my code
#include "msp.h"
int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop WDT
CSKEY = 0x695A; // unlock CS registers
CSCTL0 = 0; // reset DCO settings
CSCTL0 = DCORSEL_0;
CSCTL1 = SELA__REFOCLK | SELS__DCOCLK | SELM__DCOCLK;
CSKEY = 0; // lock CS registers
P1DIR |= BIT0;
P1OUT=0x00;
P2DIR |=BIT0;
P2OUT=0x00;
TA0CCTL1 = CCIE; // TACCR0 interrupt enabled
TA0CCR1 =5000;
TA0CCTL2 = CCIE;
TA0CCR2 =60000;
TA0CTL = TASSEL_2 | MC_2;
SCB_SCR |= SCB_SCR_SLEEPONEXIT; // Enable sleep on exit from ISR
__enable_interrupt();
NVIC_ISER0 = 1 << ((INT_TA0_0 - 16) & 31);
}
// Timer A0 interrupt service routine
void TimerA0_0IsrHandler(void) //CCR0
{
switch( TA0IV )
{
case 2: // CCR1
{
P1OUT =0x01;
}
case 4:
{
P1OUT =0x00;
}
case 10: break;
}
}
I wish the LED to be in ON condition between the instance when the timer value is between 5000 and 60000. I am unable to get and the code is getting exit unconditionally.
