One Color

This pattern turns on all LEDs of the same color at one time. It consists of 6 steps that each take just under half a second. The original version of this pattern was very slow running about 3 seconds per color but my wife complained about the "anticipation" pattern and I was forced to speed it up. This is an excellent pattern to show that you got all the right color LEDs in the right place. This pattern runs through 10 cycles of all 4 colors before advancing to the next pattern when in automatic cycle mode.

Programming the PIC

Written by Dave Baker

Microchip has a lost cost programmer called PICkit 2 which is a programmer and development platform. The PICKit 2 starter kit is available from Microchip Direct or several other sources (mouser.com or digikey.com)

Microchip released the schematics and source code for the PICkit 2 programmer so there are also several other programmers capable of programming the PIC processors based on the design. Below are a couple of links. Also if you search the web for PIC programmers you will find lots of low cost alternatives. Just make sure you can program the PIC used in the Xmas Tree. If you are new to PIC processors you may want to stick with the PICkit 2 or a similar debug/development platform.
