Example Description

This example shows how to configure the TIM peripheral to generate four different signals with four different delays.

The TIM3CLK frequency is set to SystemCoreClock / 2 (Hz), and the objective is to get TIM3 counter clock at 1 KHz so the Prescaler is computed as following:

The TIM3 CCR1 register value is equal to 1000: TIM3_CH1 delay = CCR1_Val/TIM3 counter clock = 1000 ms so the TIM3 Channel 1 generates a signal with a delay equal to 1000 ms.

The TIM3 CCR2 register value is equal to 500: TIM3_CH2 delay = CCR2_Val/TIM3 counter clock = 500 ms so the TIM3 Channel 2 generates a signal with a delay equal to 500 ms.

The TIM3 CCR3 register value is equal to 250: TIM3_CH3 delay = CCR3_Val/TIM3 counter clock = 250 ms so the TIM3 Channel 3 generates a signal with a delay equal to 250 ms.

The TIM3 CCR4 register value is equal to 125: TIM3_CH4 delay = CCR4_Val/TIM3 counter clock = 125 ms so the TIM3 Channel 4 generates a signal with a delay equal to 125 ms.

The delay correspond to the time difference between PC.06 and TIM3_CHx signal rising edges in case of STM32100E-EVAL, STM32100B-EVAL, STM3210E-EVAL and STM3210B-EVAL

The delay correspond to the time difference between PD.07 and TIM3_CHx signal rising edges in case of STM3210C-EVAL
