zimmer62 Posted January 3, 2020 Share Posted January 3, 2020 I've got a teensy for addressable LED's and on occasion I'll boot up the virtual pinball machine to find that the addressable LED's are not working. I can usually get it working with some combination of: 1) pressing the reset button the teensy 2) Unplugging the RJ45 cables from the OctoWS2811 3) unplugging and plugging the USB cable from the teensy 4) powering down the PC 5) unplugging the PC and waiting for 10 or 20 seconds for my power supplies to discharge Those 5 steps are involved in getting it working, but I don't which one or the magic that's making it work. I don't think any one step by itself was helping. I do always get it to come back up and work but I'm at a loss as to why it would do this. What trouble shooting steps should I take next time this happens? Link to comment Share on other sites More sharing options...
outhere Posted January 3, 2020 Share Posted January 3, 2020 Try a different USB cable Try all the other USB ports on the computer It's possible it could be the teensy I wish I had more ideas, I've never experienced this situation Link to comment Share on other sites More sharing options...
zimmer62 Posted February 14, 2020 Author Share Posted February 14, 2020 Okay... so the way that this gets fixed for me 100% of the time. 1) I unplug the USB cable from the teensy. (PC makes USB disconnect sound) 2) I disconnect the 5V from the Octo2811 board... 3) I plug in the USB cable back into the teensy. (PC makes USB reconnect sound) 4) I reapply the 5v lead to the Octo2811 board. Everything works at this point. Do I even need the 5V line connected to the WS2811 board? Maybe I need to tie the grounds together from the 5V power supply to the PC power supply? I bought a replacement Teensy to try that, but I'm really thinking it has something to do with either separate power supplies, or the teensy getting power before it has USB connection. Anyone else have any ideas? Link to comment Share on other sites More sharing options...
outhere Posted February 14, 2020 Share Posted February 14, 2020 The only power I have going to my teensy is Through the USB cable Link to comment Share on other sites More sharing options...
RpT Posted March 28, 2020 Share Posted March 28, 2020 In the advanced power settings in windows, check that USB devices are not set to suspend? Link to comment Share on other sites More sharing options...
seesitee Posted July 20, 2021 Share Posted July 20, 2021 (edited) Wondering if a fix was found for this, as I am having similar issues: Addressable lights work anywhere from 30s to 3 minutes. At that point, the LEDs either freeze with what ever trigger was hit, or if none the LEDs remain black. I have to stop DOF.exe, reset the USB connection, and restart DOF.exe. I know DOF is working and continues to work, because all the other toys continue to work, after LEDs stop working. DOF indicates 0 errors, as it is working fine. I have tried different, USB ports, USB cables, purchased new USB PCI board to try different ports, as well as checked the USB not to suspend - all yield in same issue. I am wondering if it is the Actual Teensy board having an issue. Anyone else experience something similar or currently experiencing the same?
