Finally I made my APA102+RPI3 (OSMC)+Samsung TV - everything works fantastic, fast and smooth.
I can grab video source from TV (using scart out) and KODI.
I want to know, if there are ways to grab video from USB SOURCE of TV and Youtube.
SCART gives only TV cable output.
No. I bought the second RPI)
NRFNetwork Library is a crap. Doesn't work well for 2 level nodes(
I tried MySensors lib. Much more better. (https://www.mysensors.org/build/connect_radio)
but Who has working version?)
I checked many times, connection is correct. Everything is the same as at my pic, I'd posted on the 2nd page.
I stopped my demon with socket server, which controls NRF24, kernel panic disappeared on setColor! (ok I will try to solve it later)
When I start hyperion all leds became off. But there is no rainbow swirl effect. Led doest work. I cant control it. So spidev0.1 doesnt work.
Suggestions?
I believe that it is wiring problem. I found mistake:
led CL was connected to 1A (SCLK)
led DI (MOSI) was connected to 1Y
On hyperion start all leds became off.
Now - all connections are correct, but several leds are on after hyperion start.
Please, confirm that:
1Y <-> led CL
GPIO10 <-> NRF24 MOSI <-> led DI
GPIO11 <-> NRF24 SCLK <-> 1A
GPIO7 <-> 1OE
What if you drop the Hyperion led count to 1?
Do u mean software limit to 1 ?
I checked kernel logs. Found these strings:
Oct 17 09:42:58 raspberrypi kernel: [ 298.757680] spidev spi0.1: SPI transfer timed out
Oct 17 09:42:58 raspberrypi kernel: [ 298.762156] bcm2835-dma 3f007000.dma: DMA transfer could not be terminated
Guys! Finally my hyperion works with OSMC and spidev0.0
Now the next step - adding nrf24
I connected 74ACT - nrf24 works correctly as before. But hyperion through spidev0.1 gives me kernel panic every time when I setColor
It looks like it has conflict.
What can you advice me?
Solved!
Really bad chinese power supply. Was changed to another 12V with DC-DC step down.
Re-soldered all segments.
Do not judge me)
Here is my power supply. 15W in enough for 2 meters. (In my case 1.5m)
1st led in the second part (first part has 15 leds, second - 32)
I dont have level shifter
I measured power supply, it gives 5.12v - 5.16v
I have to try(
There is another big problem:
1) Red was one
2) then I stopped Hyperion
3) after 10 minutes, I saw, that there are several white flashing leds. -> I removed power and all wires from RPI
4) nothing works )) Connect wires, give power. Only 1st led flashes white.
Is it possible, that all led strip was damaged? how to diagnose led strip and each led?
Led: WS2801 (32+15 leds)
Power Supply: 3A 5V
RPI 2
I had flickering problem, but it was solved by soldering all wires. External 5v connected to RPI GND.
So here is my problem:
I set red, all leds are red - then 1 sec later, this led changes his color to opposite
If blue - it became red and etc.
I noticed, that if I use half brightness, led stays in correct color.
All other leds look stable, but this one flashes quickly with different colors.
TMRh20 RF24 + NRF24 Network
It crashes sometimes as well. But these crashes are predictable, and I use linux "forever" to restart my init.d script
I made this wiring scheme, tomorrow I will try to connect all these things:)
Finally I received this chip. Guys, is that right position? Bottom-Left -> GND ? I don't understand
Left side is more bevelled
I made my first prototype, looks like crap)
I leave it here:
No such kind of chip in my country, so I ordered it from aliexpress. 1 month to wait )
Thank u guys!
1. Do I need to use resistors in this circit?
2. So both NRF24 and LED connect to one pin?
2 DI -> Raspberry PI GPIO 10 (SPI_MOSI)
Actually I dont have. I can order this: link to aliexpress
I found many different chips at my local store. I can buy anyone.
Which one was tested?
