Throw it away use the spi pins on the rpi..you dont need any additional box...

DI CI wiring example:
-
Hi,
In another Forum I see a DI CI wiring using Pins 19 and 23.
I'm asking because I'm planning an Ambilight and I' m little confused. -
Greetings,
my issue as i didn't followed the numbering schema
https://www.raspberrypi.org/do…age/gpio-plus-and-raspi2/If you compare the picture that are still the same positions. I will correct that in future.
-
The box converter is a level shifter. Max 8A.
I replace today ws2801 by apa102 (36/m) but it doesn't work. I replace the hyperion.conf with apa102 settings.
The leds doesn't lights up.
I also replace my power supply by one that is 20A.I don't understand what's wrong....
-
config pls
is spi active? -
It works fine with ws2801 so i suppose that spi is active. EDIT : lsmod return this "spi_bcm2835 6756 0"
Wich config do you want ?
-
ok that sounds good.
the hyperion config with your apa settings

// NO FRAME GRABBER CONFIG
// NO KODI CHECK CONFIGyou have no grabbers?
edit: oh sorry forget the usb-grabber...
may there is the problem...
can you start hyperion via ssh and post the output?
-
This is a V4l2 grabber (utv007)
The start effect (rainbow swirl) doesn't work.
May be a power issue ?
When i check the power at the start of the strip i get -0.5V. (I put the black pin of the tester on the GND and the red one to the 5V), why i get negative power ? -
I get the log from hypercon :

everything looks good on software side, may more a hardware issue? is your led stripe in a shrinking tube? if yes, remove it, maybe the cablecolors are not matching the right pins... if you connected the wrong pins, maybe the first led is broken now...this could also be an issue now...
-
no shinking tube but i will check the pins and give feedback. Thanks !
-
Well, the GND and +5V was not matching.....so i suppose that the clk and data was not match
I cut the first led , and soldering in the right way but nothing works. I suppose the led strip is broken.
Does anyone know a way to easily test the led strip? -
power it with gnd + 5v, and then use 2 jumper wires (clk +data) and go the to pins before the leds and test which will work maybe onky a few at the starts are broken
-
-
oh hell no!
gnd + vcc is ok, but dont shortcut! 2 wires from your pi data and clock, then you hold the clock wire on clock IN on the led-stripe and the data wire on data IN and see if the led blinks, if not, move the wires to the next data and clock IN port
but before you do this be sure hyperion is started and you set a fix color ( for example "hyperion-remote -c red")
-
ok i understand
Thanks a lot !
