Hello,
i want to configure the Timer 5 with an external Clock (Button).
This is my code, but it doesn't work correct:
GPIOA->MODER |= GPIO_MODER_MODER0_1; // Enable AF mode for A0
GPIOA->AFRL = (GPIOA->AFRL & 0xFFFFFFF0) | 0b0010; // Select AF2 for
A0 TIM3/4/5)
RCC->APB1ENR |= RCC_APB1ENR_TIM5EN; // Enable TIM5 clock
TIM5->CCMR1 |= TIM_CCMR1_CC1S_0; // Input mode, map TI1 to IC1
TIM5->CCER &= ~(TIM_CCER_CC1P | TIM_CCER_CC1NP); // CC1P and CC1NP = 0
for rising edge
//TIM5->SMCR |= TIM_SMCR_SMS; // External clock mode 1
TIM5->SMCR |= TIM_SMCR_ECE;
TIM5->SMCR |= TIM5->SMCR; // Trigger selection: TI1
TIM5->PSC = 0;
TIM5->ARR = 2;
TIM5->DIER |= TIM_DIER_UIE;
TIM5->CR1 |= TIM_CR1_CEN; // Enable TIM5 counter
Do you have an idea what's wrong?
Kind regards
