Added sensor map to Firmware <=> RTE inferface: The sensor map contains a list of up to five sensors which may be connected to the external interface. The update includes the definition of the type as well as the data structure. to ensure compatibility the RTE and needed RTE version has been set to 3.0

                      ##### TIMER Generic features #####
  ==============================================================================
  [..] The Timer features include: 
       (#) 16-bit up, down, up/down auto-reload counter.
       (#) 16-bit programmable prescaler allowing dividing (also on the fly) the 
           counter clock frequency either by any factor between 1 and 65536.
       (#) Up to 4 independent channels for:
           (++) Input Capture
           (++) Output Compare
           (++) PWM generation (Edge and Center-aligned Mode)
           (++) One-pulse mode output               
   
                        ##### How to use this driver #####
  ==============================================================================
    [..]
     (#) Initialize the TIM low level resources by implementing the following functions 
         depending from feature used :
           (++) Time Base : HAL_TIM_Base_MspInit() 
           (++) Input Capture : HAL_TIM_IC_MspInit()
           (++) Output Compare : HAL_TIM_OC_MspInit()
           (++) PWM generation : HAL_TIM_PWM_MspInit()
           (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
           (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
           
     (#) Initialize the TIM low level resources :
        (##) Enable the TIM interface clock using __TIMx_CLK_ENABLE(); 
        (##) TIM pins configuration
            (+++) Enable the clock for the TIM GPIOs using the following function:
                 __GPIOx_CLK_ENABLE();   
            (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();  

     (#) The external Clock can be configured, if needed (the default clock is the 
         internal clock from the APBx), using the following function:
         HAL_TIM_ConfigClockSource, the clock configuration should be done before 
         any start function.
  
     (#) Configure the TIM in the desired functioning mode using one of the 
         initialization function of this driver:
         (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
         (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an 
              Output Compare signal.
         (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a 
              PWM signal.
         (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an 
              external signal.
         (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer 
              in One Pulse Mode.
         (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
         
     (#) Activate the TIM peripheral using one of the start functions depending from the feature used: 
           (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
           (++) Input Capture :  HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
           (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
           (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
           (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
           (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().

     (#) The DMA Burst is managed with the two following functions:
         HAL_TIM_DMABurst_WriteStart()
         HAL_TIM_DMABurst_ReadStart()
