Give the flow chart for a program to turn your PIC board into an LED flashlight - PORTB = input - PORTC \& D are output (the LED's) - RB0: All lights turn off ( PORTC = PORTD =0) - RB1 : Half of the lights are on (PORTC=0,PORTD=255) - RB2 : All lights are on (PORTC =PORTD=255) save energy, one LED turns off every 500ms. all LEDs are off, they remain off until RB1 or RB2 are pressed. Write the corresponding assembler code
