@par Example Description 

This example provides a description of how to use a DMA channel to transfer
continuously a data from a peripheral (ADC1) to another peripheral (TIM1) supporting
DMA transfer.
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.
