This isnt complete, but should be a good starting point for others to learn from.
1) Here is where the led device source is located:
cd libsrc/leddevice
2) Find the files that need changing:

LedDeviceAtmo
LedDeviceFactory
LedDeviceFadeCandy
LedDeviceHyperionUsbasp
LedDeviceLightpack-hidapi
LedDevicePiBlaster
LedDeviceWS281x

* Fixed compile error when no grabbers are defined
* Remove stupid avahi warning...
* Started on the new integrated UDP listener to replace the python effect.
Cloned boblight server and rename it to be UDP listener
It compiles!, It starts! it seems to work as a second boblight protocol server...
* moving from the exsting TCP to UDP.
i can catch packets now.. need to consider ditching the connection handling
* It kinda works right now.
UDP packets are received, led data is sent and hyperion displays them.
.... for a moment before going back to what it was doing
* It works!
looks like the default priority of 900 was fighting with something else that was also 900
commented out some udp packet debugging
* oops, forgot to add the changes the the previous commit
* resolving merge conflicts
* Fixed random http port due to uninitialized _port
* cleaning up compiler warning
* cleaned up CMakeLists to remove warning:

* remove old serialport
add logging to serialport
* remove try catch - qt serialport uses plain return values
* tiny fix, but not working atm
* make it work, tested with adalight
* cleanup: remove ambiled device
as written at the forum this is no longer supported. All people should move to adalight. They just need to flash a new sketch.

* implement make install
set CMAKE_INSTALL_PREFIX e.g. to /opt to install to /opt/hyperion
set ENABLE_SYSTEM_INSTALL to ON to activate installation
after compiling use
make install
or
make install/strip
(for performance/size optimized binaries - compile in Release to get best performance)
* cleanup cmake files
use
cmake -DINSTALL_PREFIX=/opt/hyperion ..
to install all files to hyperion or
cmake -DINSTALL_PREFIX=/usr/
to install to usr. install folders are linux standard. bin go to bin folder and additionals (effects) go to share/hyperion
* add uninstall target - be patient with that, this will remove files from your system
install service files to share/hyperion - if you want to use them you have to make a symlink to your location of service files
* optimize build release script
install service files into hyperion share folder (services not activated, this must be done by distribution package script)
initial support of cmake option -DPLATFORM= option. This selects platform specific cmake flags. no need for -DENABLE_... options (unless you want some special things)
automatic detect for apple build
* update submodule

* add hypercon compat
* add posibility for multiple config files. first one found is taken
* remove hyperion comaptlayer
services is not started automaticly

- cleanup
* add deb package dependencies
* wipe out last support for /opt installation
* change default effect path in config to /usr
* revert service files and config files
* remove last occurences of ENABLE_PROTOBUF

* Removed -HUP so the default -TERM signal is sent instead.
- hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config
Changed pgrep to add '-x' so it wont partial match on the exe name.

* This add a new device type - ws2812spi.
I've (ab)used the SPI interface to send the correct timing pulses to keep the ws2812 happy.
THE RATE IS IMPORTANT!
A FIXED CORE_CLK IS IMPORTANT!
Attach the SPI MOSI pin on the Pi to the DIN pin on your ws2812
"device" :

"name" : "MyPi",
"type" : "ws2812spi",
"colorOrder" : "grb",
"output" : "/dev/spidev0.0",
"rate" : 3800000
},
* updated hyperiond.test-binary
* Updated default SPI speed to the "correct" value.
My Pi was undervolted so was dropping the core clock confusing everything
* Code cleanups
explicitly set the final 3 bytes to 0
* Removed latchtime option - not applicable

* started bug fixes for APA strips with more physical leds than configured
* 1st cut of changes to APA102.
now looks at config for "leds" which is the # of hardware leds in the strip.
This enables us to write the correct trailer length in the packet.
Also fixed a bug where switchoff was writing the wrong # of leds
* removed commented out old code
removed debug printf
* included prebuild test binary for Pi2
* Second attempt at the fix.
BEFORE:
If you have more physcial LEDs than defined in the "leds" "index" section of the config there is random junk added to the end of the strip.
WITH THIS FIX:
In the "device" section specify the number of physical leds with:
"leds" : 212,
If this is greater than the number of led indexes, additional LEDs are set to black
If this is smaller than the number of led indexes, it is ignored
* included test binary
* Clean exit if the device config is missing or a non-supported device type is specified

* Experimental changes to piblaster code to work how i think it should
It is now assumed that the PWM pins in groups of 3 correspond to RGB channels of the led.
"assignment" : "rgbrgbrgb",
Would result in:
//Channel number GPIO number Led channel
// 0 4 0 red
// 1 17 0 green
// 2 18 0 blue
// 4 27 1 red
// 5 21 1 green
// 6 22 1 blue
// 7 23 2 red
// 8 24 2 green
// 9 25 2 blue
* Ammend pwm channel mapping comments to match the code
* 1st cut of the new more flexible piblaster pin mapping support
it works but is still rough
* removed old "assignment" handling
- prints an error messaage if found and terminates
fixed the switchoff method
* removing iPins hard coded list of valid GPIO pins
* removed iPins array for switchOff function
* code cleanups
input validation
* Handle catching (and ignoring) SIGPIPE.
You can now kill and restart pi-blaster daemon and hyperiond will gracefully recover
* added a binary for testing
* Added sample config and my modified pi-blaster version to support more GPIOs
* moved hyperiond
* removed testing binaries
move sample configuration to the configs directory
* re enabled device config display
* removed sample configuration
Former-commit-id: 95e4d4ea2fb7cb5439e8cd597883a638da61a574
* Updated smoothing options for AtmoOrb, can now choose between Orb external or Hyperion's internal smoothing.
With skipSmoothingDif you can set the maximum allowed color difference before overriding / clearing Orb smoothing during faster color change like for instance color <-> black.
* Updated inline documentation.
* Fixed command type typo in AtmoOrb device.
* Corrected variable spelling in AtmoOrb device.
* Make smoothing also match equal values for AtmoOrb smoothing differential

Config option - "invert" (integer)
if omitted, do not invert
if == 0, do not invert
if !=0, invert

The RPi 2 and 3 have two PWM channels and 3 PWM pins available to the
gpio header. BCM18 and BCM12 run on PWM channel 0. BCM13 runs on PWM
channel 1. This change allows BCM13 to be used by allowing the PWM
channel to be specified.

Add a new WS281x driver which is a wrapper around jgarff's ws281x library which
works on Pi B+, Pi 2, Pi Zero and probably Pi 3 as well.
jgarff's ws281x library is included as a submodule
