The ADC channel14 is configured to be converted continuously. TIM1_CH1 is configured to generate a PWM signal on its output. The dedicated DMA1 channel5 is configured to transfer in circular mode the last ADC channel14 converted value to the TIM1_CCR1 register. The DMA channel request is driven by the TIM1 update event. The duty cycle of TIM1_CH1 output signal is then changed each time the input voltage value on ADC channel14 pin is modified. The duty cycle variation can be visualized on oscilloscope on the TIM1_CH1 pin PA.08 while changing the analog input on ADC channel14 using the potentiometer.
