- In this example TIM7 counter clock (TIM7CLK) is set to APB1 clock (PCLK1), since
- APB1 prescaler is set to 1 and TIM7 prescaler is set to 0.

- In this example TIM7 input clock (TIM7CLK) is set to APB1 clock (PCLK1),
- since APB1 prescaler is set to 1.
- TIM7CLK = PCLK1 = HCLK = SystemCoreClock
-
- With Prescaler set to 479 and Period to 24999, the TIM7 counter is updated each 250 ms
- (i.e. and interrupt is generated each 250 ms)
- TIM7 counter clock = TIM7CLK /((Prescaler + 1)*(Period + 1))
- = 48 MHz / ((25000)*(480))
- = 4 Hz
- ==> TIM7 counter period = 250 ms
-
- Note:
- SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f0xx.c file.
- Each time the core clock (HCLK) changes, user had to call SystemCoreClockUpdate()
- function to update SystemCoreClock variable value. Otherwise, any configuration
- based on this variable will be incorrect.
