Posted on May 17, 2011 at 12:50Hi Guys,
I am trying to generate a interrput on the rising edge of center agligned pwm using TIM1_CCR4 but I keeping getting both rising & falling interrupts. Is possible to mask out the the falling edge interrupt?
TIM1_ARR=0xFFFF;
TIM1_CCR1=0x7FFF;
TIM1_CCR2=0x7FFF;
TIM1_CCER = TIM1_CCER_CC1E|TIM1_CCER_CC1NE|TIM1_CCER_CC2E|TIM1_CCER_CC2NE;
TIM1_BDTR = 0x02| TIM1_BDTR_OSSR|TIM1_BDTR_OSSI|TIM1_BDTR_AOE;
TIM1_EGR|= TIM1_EGR_UG;
TIM1_CR1 = TIM1_CR1_CEN|TIM1_CR1_ARPE| 2<
TIM1_CCMR1_OUTPUT_COMPARE_MODE = TIM1_MODE_PWM1<
TIM1_MODE_PWM1<
TIM1_CCR4=1;
TIM1_CCMR2_OUTPUT_COMPARE_MODE = TIM1_MODE_PWM2<
TIM1_CCER|= TIM1_CCER_CC4E;
TIM1_DIER = TIM1_DIER_CC4IE;
Irq_0_to_31_Set_Enable = 1<
thx
