This code is a bit of example code for APA 102 LED Strips.
Project by Bill.b.
I have been playing with a 1m length of 60 APA 102 RGB leds for my Christmas light displays.
Here is the program I have been using to test the LEDS. also a youtube video of the results. The code is not pretty as it has been built up as I added different patterns and tried different ways to use the LEDs.
The beauty of the APA 102 LEDs are that they do not require any Cfunction code.
The APA 102 require a 5v supply but the clock and data inputs work quite well on 3.3v from the PICMX170.

The 100 ohm resistors are to protect the inputs if a fault develops in the LEDs.
