Hi TPmodding
I have tried it with both 500000 & your recommended 115200 & nothing happened
but this is what happened:
I uploaded the sketch & the HyperCon & uploaded them
The LEDs all came on test sequence white, Blue & then Red & then went off
No response again until I took out the GRD on the Mega, when I did that, some random LEDs came on the top & bottom of the TV only & they were fixed colours (see photo)
One other thing I dont know if you have noticed from my HyperCon screenshot - on the left & right of TV is grey & not picking up colours but I was leaveing that for fine tuning after I got it working but they may be related, not sure
Really appreciate your help again & my next step
Thanks again!

Hi both
@TPmodding - thx for the link, I modified it with my settings as much I could understand but still no response (pls see attached the sketch)
Also Yes I'm sure its /dev/ttyUSB0 pls see attached screenshot - I also used ACM0 & AMA0 but neither responded

@NeeeeB - I have originally ticked the 4 corner LEDs were my strip was slightly bent - but after deselecting it is now showing 548

Any advice would be much appreciated

Hi all

I’m new in this space & really would appreciate your help!
have been reading a lot of material on this TV Ambient lighting & tried everything but can’t get the LEDs to work & its driving me crazy

My setup Schematic attached also I’m using:
Raspberry Pi 3 Model B+
5V WS2812B 5050 RGB 144LED/M LED Strip 2m x2 (basically using 548 LEDs & I’m ignoring the last 29 LEDs on the 2nd strip)
Wireless 2560 R3 Mega2560 REV3 ATmega2560-16AU Board
Library I tried both Neopixle & FASTLED

I don’t have a hardware issue as my Grabber works & I can see an image albeit I get top & bottom colours simulation but not my TV’s Left & Right (pls see Hyperion Grabber screenshot attached) - they just show grey on the laptop screen

I have also calibrated my LEDs & got GRB sequence which I updated my sketch with

I’m not using Kodi so left the Kodi Checker off in Hypercon & also internal Frame Grabber Disabled in the Grabber Tab
I have tried a couple of Sketches attached & had no luck - I’m not sure if I have the Prefix right based on my 548 LEDs either, if anyone can confirm that would also be appreciated.
The best result I got was the whole LED’s were lit Constant Green at one stage & I cant even get that anymore & they are off now so I get no lights at all - but at least I know they are working but not getting the correct signal

All I need is a working a Sketch & Hypercon Config please which I will tweak but need to know they already work for someone
Thanks in advance for your help
