Posted on December 05, 2014 at 19:08Hello,
I'm trying to change the duty cycle of TIM1 in PWM Mode, but somehow my code is not working.
void TIM1_CC_IRQHandler(void)
{
HAL_NVIC_ClearPendingIRQ(TIM1_CC_IRQn);
HAL_TIM_IRQHandler(&htim1);
cx++;
if (cx>450)
{
cx=0;
}
TIM1->CCR1=cx;
TIM1->CCR2=cx;
TIM1->CCR3=cx;
}
If I remove the lines
TIM1->CCR1=cx;
TIM1->CCR2=cx;
TIM1->CCR3=cx;
the code works fine, but without changing the duty cycle of course.
How can I change the duty cycle on the fly?
Thanks
