This\nblinking RED is active after the YELLOW to allow the traffic to stop co-operatively (Not \ncommanding one direction to stop directly from a GREEN state).\n\nThe code includes a Switch Debounce Task which provides for many combinations of switches to\nbe used.  The task leaves detected switch changes in a Queue where another interested task can\ncheck to see the switch state. Any switch combinations and Queues you do not need can be removed to \nreduce the size of the code.\n\nThe I/O is implemented through a PCF8575 i2s port extender driving a seven segment LED on my \nexperimental breadboard, although any six LEDs would work.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fboomerwing%2Ffreertos-trafficlight","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fboomerwing%2Ffreertos-trafficlight","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fboomerwing%2Ffreertos-trafficlight/lists"}
