AmbiLight for your Samsung TV

Version 3.0
Features:
- Added black-border detection
Fixes:
- Fixed crashing with H_LEDS and V_LEDS
- Fixed mapping with H_LEDS and V_LEDS

The lib uses partly code of zoelechat's libScreenShot, except that it sends the data via UDP to an ESP8266 controller. So, without zoelechat, this project wouldn't be able - thx man!

Demo
https://www.youtube.com/watch?v=mOQVHFVH3VQ
Due to the fact that the script does not grab the data exactly from the edges but with some padding (to avoid black borders), therefore it looks like they're a bit offset.

Requirements

adressable LED-Controller (WS28x, anything that's supported by FastLED)

ESP8266-12E (the one with the USB-port, less headache )

PSU (power-supply for LED-strip)

First install latest samyGOso as usual, if needed.

Installation

Get your LED light mounted and connected correctly and verify that it works with FastLED (use the Blink example)

Modify the attached app.ino, especially the LEDS and WiFi-settings

upload app.ino to the ESP8266

Copy libAmbilight.so to the libSo directory (usually /mnt/opt/privateer/usr/libso

Modify 99_100_AmbiLight.init to your needs (see section "Settings")

Copy 99_100_AmbiLight.init to /mnt/etc/init.d (CAUTION!!! Test first that everything works fine, before you procede to this step)

If you experience strange color, try setting the FastLED color-ordering, to a different one (like RGB, BGR, etc...).

Code: Select all

FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, BGR>(leds, NUM_LEDS);

Settings

H_LEDS amount of your horizontal leds (only on one side, top or bottom)
V_LEDS amount of vertical leds (only on one side, left or right)
SERVER_IP IP of the ESP8266
SERVER_PORT Port on which the ESP8266 operates (default 5050)
OFFSET Shift the LED data by this number (positive numbers only, max size of led-strip), generally the led-data starts at the bottom right corner (if you stand in front of your TV)
SLEEP (default: 1) the higher the value, the slower LED-change - increase this to 2 or 3 if you experience crashes
REVERSE set this option if LEDs are in reversing order

Testing
The log-output can be found under /dtv/AmbiLight.log (this is only populated in testing mode)
Use the example image, attachted here and cast it to your TV.
Modify and execute the following command.

Code: Select all

samyGOso -d -T -B -l /mnt/opt/privateer/usr/libso/libAmbiLight.so H_LEDS:36 V_LEDS:18 SERVER_IP:192.168.1.32 SERVER_PORT:5050 OFFSET:17 REVERSE TEST

You may need to delete REVERSE and/or COLOR.
If all is set up, you should at least see some lights

or with ALT

not working yetShow

Code: Select all

samyGOso -d -T -B -l /mnt/opt/privateer/usr/libso/libAmbiLight.so H_LEDS:36 V_LEDS:18 SERVER_IP:192.168.1.32 SERVER_PORT:5050 OFFSET:17 REVERSE TEST ALT

Limitations

Currently only MST-devices supported

Currently no support for "gap" on the bottom of the TV

Donation
Since I do stuff like this as a hobby - feel free to donate

ToDo
- Modify ESP8266 firmware to be controllable via smartphone

Added optimized version.

Even if I do not use this right now I want to leave a thanks for your work! Sounds promissing!
Thanks for your work and even more for sharing it!

Do you have an experience if the 0.3 sec injecting will put to much load on the system?

You can make a resident lib, even if you "hook nothing"

Updated version. Now officially v1.0

- Added support vor clockwise and counter-clockwise mount
- Optimized code for better performance
- Runs now at 0.2s with no overload after some time, TV hangs, so use 0.3s instead
- Added demo-video

I've optimized the code now, and I'm injecting with 0.2s
0.3 doesn't put to much load, although 0.2 does, so it crashes after a while (2-3 hours). Need to investigate further.
Also, I've measured the FastLED script and it takes 0.24s for the LEDs to fade from one state to another, so IMHO no need to go lower here.

I will give it a try, when I find some spare-time again

But as of now, with optimised code, it works better than expected

Do you think there's an advantage when injecting as resident compared to the current in- and deject script?

You'd save init and deinit time of each injection, not easy to quantify but probably noticeable when so often (in addition to avoid possible unstability cause).
Nothing more than inject -r and a loop inside lib needed, it's almost ready I'd say

At the very first beginning, I tried the loop, but it only received the frameBuffer that it grabbed on injection... it did not update. Therefore I wrote the bash-script.
Although, I must admit, that I did not inject with "-r", so I don't know if that was the problem, or not.

Nothing more than inject -r and a loop inside lib needed

So, I don't need all these "hooks" and I also don't need to check if already hooked "_hooked=1" ... etc?
