# Modified adalight arduino version which uses the FastLED ( http://fastled.io/ ) library.
# I found this code at https://forums.adafruit.com/viewtopic.php?f=47&t=59464#p301431 .
# For me it works much more smooth then the original code using SPI.h .
# It works pretty well with Colorswirl boblight and hyperion

#include "FastLED.h"
#include <hsv2rgb.h>
#include <platforms.h>
#include <fastspi_types.h>
#include <colorpalettes.h>

// Uses Adalight protocol and is compatible with Boblight, Prismatik etc
// "Magic Word" for synchronisation is 'Ada' followed by LED High, Low and Checksum
// source http://thai-fighter.blogspot.de/2014/05/arduino-adalight-clone-with-any-led.html
//
#include <FastLED.h>
 
///// User definitions /////
 
// Define the number of LED Controllers
#define NUM_LEDS 30

This can be used as a starting point for developing your own image e.g. for running MirageOS on an Pi3

You will need an arm64 / aarch64 cross compiler. You can use e.g. the cross compiler shipped by Ubuntu or get the toolchain of your choice for your OS.

apt-get install gcc-aarch64-linux-gnu

Now we setup the SD card. We need to create two partitions like shown below

Device                                Boot Start     End Sectors  Size Id Type
2018-03-13-raspbian-stretch-lite.img1       8192   93802   85611 41,8M  c W95 FAT32 (LBA)
