• front_power_distribution_can_rx_event_mapper
  • Receives can messages and raises events.
• front_power_distribution_gpio
  • Receives GPIO events and sets the corresponding GPIO pin states.
• front_power_distribution_current_measurement
  • methods:  
    • front_power_distribution_current_measurement_init()
      • Periodically Reads current values from all the load switches in some period of time
      • will use 4 instances of bts_7200_current_sense
      • will have a timer, every time the timer goes off, it'll read from all 4 storages.
      • raise a FRONT_POWER_DISTRIBUTION_CURRENT_SENSE_DATA_READY
    • front_power_distribution_storage_global()
      • simply returns the storage. 
• front_power_distribution_publish_data
  • Periodically broadcasts the gathered data from front_power_distribution_current_measurement
• main
  • initializes the modules, processes the event queue and passes it into the other modules.

Libraries

• signal_lightsbts_7200_current_sense
  • methods:
    • bts_7200_init(configuration)
      • configuration
        • Select Pin Address
        • Sense Pin Address
        • callback
      • initialize select pin as GPIO Output
      • initialize sense pin as GPIO Input, (adc)
      • periodically set up timers
        • every time timer goes off, we'll 
          • measure with sel 1 
          • measure with sel 2
          • update storage with that measurement
    • bts_7200_get_measurement()
      • returns whatever measurement is in its storage
• lights_signal_fsm
  • Uses blinkers to repeatedly raise events
  • Has a state machine implementing the.
  • inputs:
    • event names: signal_left_fsm_input, signal_right_fsm_input, hazard_fsm_input, sync
  • outputs:
    
    • signal_left_fsm_output
    • signal_right_fsm_output
    • signal_both_output, or you can raise a left_output and right_output...
• blinkerblink_event_generator
  • uses soft_timers to repeatedly raise an event with a data field
  • inputs:
    • event_id
  • outputs:
    
    • raising that event_id with alternating data fields.
