Prismatik not working after PC sleeps

[mattzzz100]

So im on windows 10 and managed to set up my adalight unit all fine with prismatic. Then I tried sleeping the PC to see if it will come back on after and it didnt. Now I cant get the lights to work again. Any ideas as to why this happened? I can see the unit in device manager, and Prismatik is running with the same settings as before. Thanks

Okay after fiddling with the program it will work again if I quit prismatik and restart it. Is there a way where I wont need to do this everytime after I put my pc to sleep?

with what board?

[mattzzz100]

Its a off the shelf product. Bought it from banggood, not sure what board it uses. https://www.banggood.com/Ambilight-DC5V-2M3M4M5M-WS2812B-5050-RGB-Dream-Color-USB-APP-LED-Strip-Light-for-Desktop-PC-Screen-p-1497308.html?rmmds=myorder&ID=45764554513&cur_warehouse=CN

Yeah and now even quiting the program and reopening doesnt work anymore either.

[zomfg]

You can open the box to see
But looks like you have CH340 serial chip (did you install the driver?) which has all kinds of issues
You can try this

[mattzzz100]

Yeah it is a CH340 displayed in device manager. I downloaded the driver and it worked! As for the usb setting, should I set it to keep power on the USB constantly even when pc is turned off?

[zomfg]

If it works without touching USB power settings, maybe keep it as is for now.
Otherwise, no, keeping power even when everything is off won't help

SO after updating windows, it worked as it should for a day. But now I'm back to the same problem. Doesnt work after pc wakes from sleep.. any ideas?

[mattzzz100]

After fiddling around with it more, I got it working again by changing the baud rate from 128000 to 115200 in device manager. I was trying to have this higer to make it sync with my 100Hz monitor. Is this never going to be possible?

[zomfg]

It depends on how hard you want it, see here

[mattzzz100]

Still having issues with this. Only sometimes work when I wake pc from sleep. Then to get it working again I need to shutdown the pc and restart it a few minutes later. Even that method doesnt work all the time. Now im back to not being able to get it working even after a PC shutdown/restart. :/

Having the same issue. Happens pretty much ~75% of the time when resuming from sleep. Usually to fix it I just toggle the light off and on, but sometimes this doesn't work either and I have to restart the app.

I have bought that same exact box myself. If you open it up you'll find that there's a simple Arduino UNO R3 inside of that. You can flash Adalight on it again (I however don't remember exactly which pins it uses for the LED signal but you should be able to trace it back by following the wire that is soldered to the LED connector) with your desired BaudRate if you want it to run faster.

I hava a 120hz monitor so I tried a few seetings too, to have the best direct visual effect. So here are my settings that work very nicely for me. boudrate: 500000 (change in code for arduino and in prismatik as well, otherwise it will not work, also changing the boudrate on the settingsmenu in devicemanager has no effect). Then set the grabinterval at 1ms. This gives for me the best effect.

Hi. I am very grateful to you for the work you have done. I am using on windows 10 Prismatik (unofficial fork) software 5.11.2.27 + esp flashed with WLED + Wled_wifi plugin. Everything works great, but stops after resume from sleep state. Restart application helps but after sleeping all repeats. Is there any solution?
