Posted on July 25, 2017 at 05:08hello can someone look at this code and figure out what's wrong with it. it's supposed to flash an LED for 10 seconds. but it don't. the LED doesn't come on. it will come on if i use a delay loop, but not with TIM16.
GPIOA->BSRR |= GPIO_BSRR_BS_4; // turn on LED wired to pin A4
TIM16->PSC = 23999; // 24k (PSC + 1)
TIM16->ARR = 21000; // about a 10 second count
TIM16->CNT = 0;
TIM16->EGR = TIM_EGR_UG; // update registers
TIM16->CR1 |= (TIM_CR1_OPM | TIM_CR1_CEN); // Enable and start timer in one pulse mode
while(TIM16->CR1 & TIM_CR1_CEN);
GPIOA->BRR |= GPIO_BRR_BR_4; // turn off LED
