"Ambilight clone" with teensy2.0 and WS2801 (1 Viewer)

[c3r3b3llum]

hi everyone, hi @azzuro,

i hope i'm in the right place this time.

i did the exact procedure written on @azzuro tutorial but no luck with atmowin.... i got no problem while compiling and flashing the teensy, when i launch atmowin with atmoduino and com8 and 25 led i get "connected succesfully" but there is nothing else. what ever i try to do my leds stay white. static color do not change the color of my led and live do not too.​

i should mention that i've tried prismatik (formerly lightpack) and i got the yellow shinning sun but my leds are still white, no color changing.​

other weird thing is when i plug in my led with the ac/dc adaptater, they're all shinning white. when i unplug the ac/dc adaptater, they are all shining orange.

what went wrong ? could you help me ? please !!!

thanks in advance for any answer and my apologies for my poor english.​

hello c3r3b3llum
First can you say me,
- the files used for flash ?
- what is your board : Teensy2 / 2+ / 3
- Arduino software used ? ( but if flash is OK, ne needed)

i've followed your tutorial here : https://forum.team-mediaportal.com/...-with-teensy-2-board-led-strip-ws2801.116128/

the files used for flash were found here : https://www.dropbox.com/sh/0dhu57q7jy7lr92/cvfJyexhhy
i'm using AtmoDuino4Teensy_v3.ino i've just modify the number of led (25) and this one FastSPI_LEd_4_Teensy_2.zip

My board is a teensy 2.0 and my led are ws2801 led; i've bought them here : http://www.mediahd.fr/36-accessoires-ambitv

i've followed the procedure exactly. my flash on arduino IDE is ok, after flashing i push the button on teensy for reboot as written.

the probleme starts here. when it restarts my led do not “fade-in / fade-out” nothing happen.

my ac/dc adaptateur (5v 12a) is connected to my led strip. when i connect it all the led turn white even if the teensy is not connected. i don't know if it is normal. when i plug the teensy with my adaptateur connected, they stay white.
if i unplug the adaptateur they all turn orange.
i'm using 3 pin on teensy :
Data PIN : B2
Clock PIN : B1
Ground : Common GND
(+5V) directly on LED

do you think i've copnnected something in the wrong way ?? i've triple check all seems ok....
