ARCHIVED, NO DEV! Please try WLED as replacement
This code allows you to use a ESP8266/ESP32 with a fitting led strip as extension for hyperion (ambilight clone). You need to configure hyperion to stream the leds as UDP to the esp.

It will also work with enigmalight.
Tested with following following libraries (other versions may work):
a) Arduino IDE 1.8.13
a) esp8266 2.7.4 http://arduino.esp8266.com/stable/package_esp8266com_index.json
b) for esp32 1.0.6 https://github.com/espressif/arduino-esp32
a) ArduinoThread 2.1.1
b) ArduinoJSON 6.18.0
c) LinkedList 1.3.2
d) FastLED 3.4.0
e) Logging https://github.com/SciLor/Arduino-logging-library - install manually: Download zip from github and install via Arduino IDE, Sketch -> Include Library -> Add .ZIP Library
f) ESP32 Webserver https://github.com/nhatuan84/esp32-webserver - install manually (for esp32 only)
Attention, enabling Logging can slowdown the leds responsiveness!
- Go to the
HyperionRGBfolder and create a copy ofConfigStatic.h.example. Remove the.examplesuffix - Configure the
ConfigStatic.hfor your needs:- Select your LED chip type. All LEDs of the FastLed libraries are supported
- Configure the used LED pins. You can also change the Pin Order. The NodeMCU order doesn't work sometimes to please also try the `RAW_PIN_ORDER``
- Define the number of used LEDs
- Define one of the standard modes which are active when your light is idle. Choose one from: OFF, HYPERION_UDP, STATIC_COLOR, RAINBOW, FIRE2012
- You maydefine Wifi configuration but you can also change it from the Webinterface
- Open the
HyperionRGB.inothe Arduino IDE - Compile and upload to your board
HyperionRGB will try to connected to the saved WiFi for 3 times and then falls back into AP Mode for 60 seconds. It will open a new WiFi network with the standard name "HyperionRGB" and password "HyperionRGB"- The SSID/Password may be overriden via the static config. (hostname/password)
This section describes the different UDP Protocol formats.
Standard format, will expect the leds data via udp as a block 3 bytes per LED, Full LED set
[LED1: {0: R, 1: G, 2: B}, LED2: ...]
One byte per block:
- Update ID & 0xF
- Fragment ?!
- First LED ID, high byte
- First LED ID, low byte
- [LED1: {0: R, 1: G, 2: B}, LED2: ...]
- 0x9C //magic byte
- 0xDA //data frame
- Data length (LED count * 3), high byte
- Data length (LED count * 3), low byte
- Fragment ID
- Fragment ID maximum
- {0: R, 1: G, 2: B}
- 0x36
If you just want a single wireless LED-Stripe you can just configure hyperion as always, except you need to set the fitting device as following:
{
"colorOrder" : "rgb",
"maxpacket" : 1450,
"name" : "AmbiSZ-ESP8266",
"output" : "ESP8266:19446", ///
"protocol" : 0,
"rate" : 250000,
"type" : "udp"
},
You need two running hyperion instances. The first grabs the data on e.g. a rasbperry pi and controls any local attached LED strips. This first instance is configured to forward its data to a second hyperion instance on the same machine. Be sure to only forward the UDP data:
"forwarder" :
{
"proto" : [ "localhost:19447" ]
},
The second hyperion instance is configured to use UDP as device so that it can talk to the ESP directly. This second hyperion instance can run on the same machine as the first instance. Just make sure that you set the UDP ports, hostnames/IPs and LED number accordingly to the values you've configured for the ESP.
{
"colorOrder" : "rgb",
"maxpacket" : 1450,
"name" : "AmbiSZ-ESP8266",
"output" : "ESP8266:19446", ///
"protocol" : 0,
"rate" : 250000,
"type" : "udp"
},
"protoServer" :
{
"port" : 19447
},
"jsonServer" :
{
"port" : 19446
},
Go to Confiruration -> General, select Controller type: udpraw set Target IP (your ESP IP addr) and Port (19446).
Please use UDP Protocol "UDP_RAW" in ConfigStatic.h for the ESP part. You may need to change the output to the IP of your ESP! The prefix doesn't matter as the ESP should ignore it (Untested).
