application 7 police car this is a full program application example to demonstrate how easy format handles a complicated design requirement. all the work is to be done on a single page. there are four input trigger buttons and two output pins to drive two leds. button #1: turn on (start) or off the engine. button #2: gas pedal to give acceleration sound from idle and then keep on at a steady running sound. button #3: siren sound on/off: toggle on and toggle off. button #4: brake, triggers deceleration sound and then brings the car to idle. leds outputs: blinks in opposite phase when the siren sound is on. that is when one light is on, the other light is off in an alternating pattern. time out requirements: every sound needs to be automatically shut down after a specified period if no more trigger signal is received. easy format tm application example: police car flow chart ht84xxx 28 april 26, 2000 78 7( 97 8" 8) ( 7( 7(:( # 8 7 # &) 9 7 # )& 7 8 # +& 7 ( ( # +& 7 ( 22 # "& 7 8 # "* 7 ( ( # +* 9 7 # *" 7 ( 22 # )" # ") # )+ 7 ( ( # *+ 7 8
