Question

For the timer configuration we are using the pic24FJ64GA102 . We are using MPLAbxide for programming. It's like c language

Write code do to the following

Purpose: The purpose of this lab is to create a project that mimics the Approach Lights to an airport runway. Approach lights are a series of lights that flash quickly in sequence to lead an aircraft to a runway, usually under Instrument Flight Rules when visibility is poor due to rain, fog, or other phenomena. Assignment: 1. Create a simulation of the Approach Light system (just the string of flashing lights) using 8 LEDs. Yes, 8. The Lab 2 only required 7) 2. Add a pushbutton switch the causes the lights to flash in the opposite direction-if the lights initially flashed from LEDO to LED7, depressing the switch once should switch the pattern to LED7 to LEDO. The pattern should reverse each time the switch is depressed.
