LESSON 3 “ROTATE LED” SOURCE CODE
Here is the basic flow of our Rotate LED program:
3.3.4
In the MPLAB IDE, build the Lesson 3 project and program the code into the demo
board using the PICkit 3 Programmer.
The demo board LEDs will rotate from LED 0 up to LED 7 and then back to LED 0.

The global variable LED_Number, which holds the number of the LED we cur-
rently want on, is set to ‘0’ for the first LED.
The TRISD register bits are all set to ‘0’, so that all 8 port D pins RD0-RD7 are
outputs.

LED
The number of the LED to turn on, LED_Number, is used an index
to the array LED_LookupTable which returns a value with a bit set
corresponding to the LED to be turned on. This value is written to
the LATD register to turn on the one LED.
The LED number is incremented to the next LED. The if state-
ment checks to see if it has been incremented past the last LED. If
so, it is reset to the first LED, number 0.
As in Lesson 2, a “delays” library function is used to create a time
delay.
