Parameters

trig_pin	the pin attached to the triggering signal
echo_pin	the pin used to measure round-trip time of ultrasonic pulses
input_timer_queue	the input queue that receives data from IRQ
output_range_queue	the output queue that receives computed range
echo_irq_call_back	The ISR (interrupt Service Routine) that process IRQ event
event_mask_config	the rising/falling edge configuratio of the irq
