@UFD said in I2S Issues:
are (0.2.2 b200)
Somewhere I read they disabled i2s audio, if you search the forums there is more info on it but no one from Onion.io has made any comments on it. Better to submit a help ticket if possible. I had to downgrade the fw to use audio as well. The other work around that I found that does work, though I hate it, is using a USB audio driver.
At some point the MAX98357A i2s power amp used to work over i2s. If you read on the forums people had issues above b193. Is there a way around the issue and fix i2s to be able to have audio out?
Thanks
I had someone make me 2 versions of node. v8 and v9. I am using v8 successfully for a while now. I also had upgraded the npm.

Let me know how you like it, install it using opkg.
Well fingers crossed you get this working 
Any updates on this? 
My recommendation is using NodeJS. I use NodeJS with Azure IoT Device and I dont run into any storage size issues. One little trick I found, install all your modules in /tmp, then move the node_modules folder to / . The folder will be highly compressed once its in flash memory.
MAYBE the cable was 2 separate USB connectors, 1 for webcam, 1 for microphone? Like a Y connector with shared power / gnd? no idea lol
I am building a Hub that supports POE as well. The circuit I am using supports 12-48v DC (dont want to deal with diode rectifier for AC) POE injectors. I am actually using Ubiquity as one of the POE testers.
You have a lot more passive components than I do. Mine only uses 12 BOM line items. (14) total. Maybe because my Ethernet Jack has the Harmonics built in. Either way, good work.
USB 2 is only 4 wires. Is it USB 3.0 or USB C?
Cant you change your network IP settings in etc/config/network ?
I went on Alibaba / Aliexpress and found the factory that makes the oled display 1". tested and works, cost is only like a dollar and change.
Attaching TFT displays to the onion , there are issues with SPI from what I remember. Nexon is one way to go but that is all screen driven over serial.
There are "ways" to do video over USB... kind of like webcam over USB just in the other direction Good luck though. Here is a reference:
https://hackaday.com/2013/01/07/adding-an-lcd-screen-terminal-for-tp-link-routers/
Pi Zero W is a loss leader. That part can someday disappear. I agree spec wise its better but Onion is much better when handling network tasks IMO. Dual WiFi, 5 Ethernet Ports, etc. It's also PCB board solderable. If the Pi Zero W was PCB board solderable I would of went with that part.
microUSB is for power and UART. You can connect peripherals to the full size USB port and add a USB hub to create multiple ports if you need more than 1 device attached.
FYI on the original post, I had some webcams just not recognize in the Onion. It's gonna happen, driver issues. Also encoding issues where some camera's only output H.264/265 format.
@frederic-raducki
Huh? I have been working on webcam streaming now on a side project for a bit. I dont quite understand what you are doing. For me I made a web based door bell camera with onion + webcam that did reverse SSH to a server in the cloud and streamed the webcam feed to the server, from there I made it publically accessible and could view it anywhere. That is the quick version
FYI mjpeg-stream is in mjpeg format lol. What its doing is sending lots of photos a second and you view it as video. mjpeg-stream is limited. Look into ffmpeg if you want different file formats. Also, I used a program called Shinobi cctv to encode the mjpeg stream in mp4 files broken out in 1 minute chunks.
I am building out an IoT Hub around the Onion. Right now it will have these components:
-POE + Data (Ethernet obviously)
-Omega Onion 2S+ (SMT Version)
-SD Card holder
-Temperature / Humidity / Accelerometer Sensors connected over i2C
-4 port USB Hub. 2 External USB connectors, 2 internal USB connectors
-Maybe header pin adapter for optional 3G modem SIM5320A.
Anything else I should add? Maybe placeholder for xBee on the serial line? I made my own FCC certified 915MHz radio so I may add that on there or keep a place holder there for future development but what would the community want in a small IoT Hub?
If I upgrade to the latest OS, I get kernel panics and the Onion reboots.
If I downgrade to version 160, I dont get any kernel issues but I cant do anything with i2s. Has anyone gotten this to work:
The new OS release has Kernel crashes when trying to do things with Audio. I cannot seem to run through these steps without a crash:
https://onion.io/2bt-omega-i2s-audio/
I am trying to use a USB microphone but I keep getting a kernel crash when I try and run "arecord".
