PWM at Raspberry Pi GPIO Pinout

GPIO18 is pwm0 because its the first one.

You can also use pwm1

Quote from swap_gore

RPi is powered up by SMPS (used in desktop). Its voltage is 5.23V.

your voltage is not the problem but the current it can draw from the PSU/resistance in usb cable?

it seems you are missing common GND

lay a wire ( -) from your barrel connector that's connected to the LED's to a GND PIN of the Raspi, any ground PIN will do ( if you can do 2 ground PIN even better)

Ground at Raspberry Pi GPIO Pinout

also increase LED settings Connection Attempts to the default of 12

Use GPIO10 for SPI ( hardware PIN 19)

second of all, if possible solder all connections

- power from both sides GND separate and +5 volts separate on begin and end of ledstrip ( if possible in your setup)

- increase the PSU +5volts to +5.3 volts

- loose the barrelconnector and use Wago's or anything thats not causing resistance like soldering on your PIN's directly, those jumpercables are known to mallfunction ( having resistance) on data PIN ALOT!

goodluck!

no, execute them in the terminal or SSH with program Putty >> port 22

if the device (vendor) is visble then you can see the device as MAC adres, first 6 digits is the vendor of the device. if not shown at all then the device is not recognized by the OS of the Raspi. This problem can be that Raspi is not powerfull enough in power/data to engage the Grabber because its 3.0 USB protocol and Raspi wants to run only 2.0 USB.

OR/AND

i would recommend writing a new image of Hyperbian version 2.013 >> do NOT format the SD card but write it on empty volume!

goodluck.

okay, i am running a Raspi 3b and Hyperbian version 2.013 and never had a problem.

i use a external grabber 2.0 USB ( coffee black) on USB port 2.0

i think your problems come from the fact that external grabber 3.0 doesn't run well on 2.0 USB port.

means: its not receiving frames from the USBdevice, raspi is not recognizing the device.

you can also determen that with this code:

lsusb

or

dmesg

Quote from swap_gore

Unfortunately it did not work.

Let me format and reinstall Hyperion on RPi.

Important: only write the image onto the SD card. Make it first empty volume

No format is nessesary for Raspbian

RE: Video capture card don't show in pi zero w hyperion

stick the capturing device into the USB2.0 slot and try again.
if that's no sollution then update the firmware

first.

sudo apt-get update
sudo apt-get upgrade

these commands will push the new updates to your machine> when connected to internet ofcourse
for the rest what to do, let me have a look

try this

apt-get install hdmi2usb-mode-switch

if that doesn't work, SSH or terminal
apt-cache search firmware

find these 2

this should help if you are lucky and tried everything else

try the last post that I posted there.

and increase USB power with a extra line in

config.txt 

In config.txt add a line

max_usb_current = 1 

and reboot with sudo reboot Try also to increase PI power onto 5.3 volts, if PI runs to low on voltage then USB port power is even lower then 600ma, so maybe only 4.8 volts and 400ma max Measure the power to the PI WITH load

try switching on and off leds at remote section. Leddevice

Quote from solidious77

This makes me feel much more confident about it being the lights itself

it seems like it.

you have only 1 option left: run with SPI > but to be honest i don't think it would matter much.

before you send back the ledstrip you can try a levelshifter on SPI or PWM

PWM on 5V GPIO pin

I have a 12V Noctua industrial fan (it's for a project, the amount of airflow is needed). The fan doesn't turn on by itself (with only 12V and GND connected),…

I've certainly gotten myself in over my head

i remember something:

i had a guy this week who also coulnd't activate the ledstrip at GPIO18 on a Raspi4

try to run it on PWM1

>>

GPIO13 PWM1 hardware PIN 33

OR

GPIO19 PWM1 hardware PIN 35

Quote from solidious77

I believe I've done this with a jumper directly from the PSU negative port, to Rpi ground pin. In the negative PSU, I also had the two white ground wires from beginning and end of LED strip.

that's good, but> use at least two GND PIN of the Raspi, sometimes one GND PIN isn't enough

1. 2022-09-10T19:12:15.730Z [LEDDEVICE|First LED Hardware instance] (INFO) LedDevice 'ws281x' enabled

means everything is running like it should, i think ( believe) your problem lays in hardware.

It can be the ledstrip that's faulty or connections>> or you need a levelshifter to boost up your dataline from GPIO18

i have to say, most members don't need that shifter.

you can crank up the voltage to 5.3 volts on the Raspi and ledstrip. Sometimes thats just enough to get the stuff rollin..

Thanks again for the help by the way. I've certainly gotten myself in over my head

my first Hyperion experience took me almost a week to get running that was with the old Hypercon

no problem, i love to help

Quote from solidious77

and the rest are as you mentioned:

no startup effect so ever? see my post about the mallfunction.

take the SPI route instead,

Or post here your debug log so we can see

important: u have to use a common GND when using two separate PSU for ledstrip and Raspi

Power begin and end.

Check settings of ledcontroller

WS281X

PWM0

GPIO18

turn whites off. >> (V) deselect

If that doesn't work, try to skip first leds and start there with power and Dataline, maybe first o e is faulty >> they are daisy chained

Quote from solidious77

especially with no errors in the log.

Look at remote section in Hyperion.NG, leddriver should run

log in as Expert user on WebUI and go to

Logs

Select Debug and reboot

After that go back to that section and copy paste Debuglog with pastebin into the forum

or you are having badluck and need a levelshifter to increase voltage on Dataline

What is WS2812b LED and how to use WS2812b LED

WS2812 LED also called WS2812b LED, wiring diagram, programming with Adafruit, Arduino and Raspberry PI, products and applications.

www.sdiplight.com

and last thing: make sure you are running under root. Raspi has to run root acces to be able to use PWM

use this code in terminal:

sudo updateHyperionUser -u root

last thing what comes to mind, besides the capturing is working/or not properly or turned off.

at least when everything connected well together and programmed, the start up effect should at least be working.

see>

if its not you can be sure: something is not correct or faulty in the hardware OR something happened in installation Hyperion image or corrupted installation.

some members have sometimes a hardtime to powerup PWM0 GPIO with any given ledstrip.

You can also use SPI on this ledstrip ( if its really impossible to run the ledstrip with PWM)

then select SPI ledcontroller

spidev0.0

GPIO10 ( hardware PIN 19)

baudrate 3000000 baud (default or higher)

dont forget ( most times its activated)

dtparam=spi=on 

goodluck!

Quote from solidious77

WS2812B male end (data arrow towards

This should be in reverse.

Arrow should be AWAY from Raspi and Gpio's

arrow pointed 👉 to end of ledstrip

If possible: power from begin and end

So +5 volts ⚡️ begin and end

So GND begin and end.

Make common GND on 2 GND pins Raspi and GND/V- PSU and ledstrip GND when u use only one PSU for everything

is really something else.

You running as root command (not even correct one but okay) doesn't have to do anything at all with dhcp ethernet module Co nectwd to Raspi OS

That's the Raspi. do a search in your router and/or restart your router that distributes dhcp ip addresses

yes, android Grabber (trough PROTO buffer) works.

But: Amazon video and Disney+ Netflix etc don't work,

Second: very poor image and FPS

For the nicest results I would recommend the HDMI route

Second Android grabber and thirth the camera 📷 route.

With last mentioned you'll evade every DRM or HDCP problem, drawback is quality 👌

yes ofcource, you can use the HDMI also

But WebUI you need ( LAN/WIFI) from hyperion webserver to make your settings
