"accepted connection" but no lights
First thing to say is great project, I am using raspberry pi 3 with ws2812b leds connected via SN74HCT125N logic buffer. The strandtest.py and singlestrandtest.py both work using... root@raspberrypi:/home/pi/rio/rio-server# python ./firmware/rpi/singlestrandtest.py Press Ctrl-C to quit. and... root@raspberrypi:/home/pi/rio/rio-server# python ./firmware/rpi/strandtest.py Press Ctrl-C to quit
after reboot I then run this first... root@raspberrypi:/home/pi/rio/rio-server# python ./firmware/rpi/server.py and get... Opening socket... Listening...
In another terminal i then run... root@raspberrypi:/home/pi/rio# npm run server and get the following output and then the rio gif playing in the terminal window only
[email protected] server /home/pi/rio cd ./rio-server && npm start
[email protected] start /home/pi/rio/rio-server node index.js

...the rio gif now appears
I can see over in the other terminal that "accepted connection" now appears after the word "Listening"
In a third terminal window I enter this and get app.main...
pi@raspberrypi:~ $ ls /tmp app.main dhcpcd-pi ssh-7ZeY9epPkKdF ssh-dja66qrhWrUg systemd-private-81a092c6c05543848163712ddf01092f-systemd-timesyncd.service-OKVx6R
But still no lit leds, perhaps you could steer me in the right direction thanks Dave
Could this be a duplicate of my current issue? https://github.com/SolidStateGroup/rio/issues/13
Could this be a duplicate of my current issue? https://github.com/SolidStateGroup/rio/issues/13
I have read through all the comments and cant really say if its the same because I,m a complete newbie at this
would commenting out the slacktoken and twitter stuff below in config/index.js get me anywhere ?
Hi @dallen98 commenting out those fields won't help but it will lead to a cleaner console output. We need to turn those off by default really.
It sounds like you're definitely really close to getting your LED's working with rio! First things first, you don't need to manually run any python script to communicate with the wall. The python script is actually run from within the node process so all you need is npm start from within rio-server. Take a look at rio-server/outputs/pi-output.js.
It is therefore possible you configured the wrong python script? The one you need to configure to suit your own LED wall is rio-server/firmware/rpi/lowlevel-server.py. Let me know how you get on
Feel free to also link me/attach your python script and your rio-server/config/index.js
Hi and yes I can confirm the "npm start" works for me,
I can see in server/outputs/pi-output.js mention of lowlevel-server.py
In my rio-server/firmware/rpi/lowlevel-server.py I guesssed at the number of pixels and wrote 50 on pin 18 and 50 on pin 19 because ive got them still in there original reels across my desk. Question is it critical to have the LED_COUNT exactly right before I can see anything ? same question with the matrix Thanks
No I do not believe its critical to get the LED count right for them to light up. Just to be sure have you definitely enabled sendToPi in rio-server/config/index.js? I have pushed a change to master that outputs stdout (i.e. the print statements) from the python script. Can you confirm that you see these 4 lines after running npm start:
Python output: Opening socket... Python output: Listening... Python output: accepted connection Sending a9437df0-fa15-11e8-b9c1-f93bdbdd54e0
The GUID on the last line will of course be different.
Hello I did a fresh install on my pi3 with raspbian full version, I have npm and node now installed being... pi@raspberrypi:~ $ node -v v11.4.0 pi@raspberrypi:~ $ npm -v 6.4.1 having cloned your newly revised rio yesterday and successfully run the strand tests I start it with... root@raspberrypi:/home/pi/rio/rio-server/firmware/rpi# python lowlevel-server.py Opening socket... Listening...
In another terminal root@raspberrypi:/home/pi/rio/rio-server# npm start and get the following output..
[email protected] start /home/pi/rio/rio-server node index.js

then the gif plays, what i,m not seeing is lights or your fourth line that begins with Sending XXXX....
I then reboot and retry with just the... root@raspberrypi:/home/pi/rio/rio-server# npm start and get the same output result and no lights, could it be that the "Sending... is not seen because the terminal window blinks very/to quickly from "accepted Connection" to gif in which case a 10 second delay between inserted between "accepted connection" and "Sending might resolve this ???
I then try ls /tmp and can see app.main I have sendToPi as true
what follows below is the log of the rio installation...
d rio && npm run install-server gives this output....

Ah you have sendToConsole enabled, please disable that when outputting to LEDs so you can continue to see console messages Your install log looks normal. It is possible that outputting to console might have been having an effect on outputting to the pi. Try with sendToConsole disabled and let me know if it makes any difference.
Also please paste your lowlevel-server.py
Blimey activity on my lights at last, I dont have the led,s formed into a matrix yet so cant tell if the output is gibberish but hey looking good thanks

Awesome yes i took at the code and we were prioritising sending to console instead of sending to LEDs. I have now changed that in master.
By the way if your matrix is 15x4 then your LED counts in lowlevel-server.py file are wrong.
About the matrix, I plan on a 16:9 aspect ratio screen so I calculate for example 48 pixels wide by 27 pixel rows high (48x27=1296 pixels total) (1296 divided by two = 648 LED_COUNT on pin 18 and ditto 648 LED_COUNT on pin 19 matrix: { width: 48, height: 27 I believe it is the case that the max numer of pixels is 2040 eg 1020 on pin 18 and 1020 on pin 19 and so concievably a 16:9 screen could be up to 60 pixels wide by 34 pixels high but no bigger which is what I see in your config/index.js Let me know if all the above sounds right thanks
Yep that all sounds right. In fact the wall we built for use with rio was 60x34 and 2m wide! I cannot recall what the maximum number of pixels you can drive through each GPIO pin is, I believe its just the more you have the more your update rate suffers. Assuming you are powering the strips with an external 5v power supply 1296 pixels will be a breeze.
I see the simpsons video gif on your rio intro page there seems to be some dropout of pixels towards the bottom of the image, did you have any problems playing full motion video across the 60x34 pixels ? is there anywhere in the code to alter the framerate up or down ?
Nope that would just be our primitive electrical skills! We found that the wall had to be evenly powered across all the strips and I think towards the bottom had less power running through it. I think the entire bottom strip might not have worked due to some issues during soldering :D.
With regards to framerate, in the case of GIFs the delay between frames is pulled from the GIF itself. In order to effect it you'd have to manipulate the delay returned from inputs/gif-worker.js. As for video input, the framerate is currently hardcoded to 12fps. You can change this in inputs/video-worker.js on line 32 making sure to also update line 45 to provide the appropriate delay to the frame sending pipeline.
Is the frame rate restricted by the distance the signal has to travel (in my case 2 meters x 1.1 meters using the 30 pixels per mt ws2812b) or is the raspberry pi cpu/gpu the bottleneck, I have on order the newest rspb 3+, will be giving it a try. Also is there a way to get the server to look in a file on the raspberry pi for a stored video ? instead of the youtube/giff downloads. Thanks
