   Designed to work on Nucleo_L476RG
   TIM1 ch1N and ch2 are used for output generation (TIM1_CH1N_PIN, and TIM1_CH2_PIN).
   It is important that both channel are on the same timer, in order to check influence on channel dependant API.
-  Management of interruption is done with variable incrementation.
-  TIM8 ch1/ch2 are used to measure frequence and duty cycle of TIM1_CH1N output generated signal
-  TIM8 ch3/ch4 are used to measure frequence and duty cycle of TIM1_CH2 output generated signal

   Regular channel and complementary channel (TIM1_CH1N) are tested.
