Example Description

This example shows how to configure the TIM10 peripheral in PWM (Pulse Width Modulation) mode.

The TIM10CLK frequency is set to SystemCoreClock (72 MHz), to get TIM10 counter clock at 24 MHz the Prescaler is computed as following:

The TIM10 is running at 36 KHz: TIM10 Frequency = TIM10 counter clock/(ARR + 1) = 24 MHz / 666 = 36 KHz The TIM10 CCR1 register value is equal to 500, so the TIM10 Channel 1 generates a PWM signal with a frequency equal to 36 KHz and a duty cycle equal to 37.5%: TIM10 Channel1 duty cycle = (TIM10_CCR1/ TIM10_ARR + 1)* 100 = 37.5%

The PWM waveform can be displayed using an oscilloscope.
