I’m sure I am asking this question the wrong way but hopefully I can explain and it will make sense to someone. I am building some Christmas decorations for a friend of mine that will have some leds on them. Going to be using these pixel strips…
Odlamp 50pcs WS2811 Dream Color Changing RGB Addressable LED Pixel String Light Waterproof 12mm DC12V for Christmas Party Advertising Board Decoration (DC12V 50pcs) https://a.co/d/2JJbOEs
They will be hooked up to a D1 mini esp32 with a SN74AHCT125N
It will be on some candy chains so I will set them up to basically flash red and white. Setting it up to do what I want them to do isn’t the problem, my question is how can I set it to where when he plugs them in 11 months from now it will do what I have them set to do? Is there a way to make sure the setting sticks? Trying to avoid having to do long distance tech support lol. I know I can make it a preset and set that preset to come on at boot. I guess I’m just trying to make sure it will hold that setting permanently. Hopefully that makes sense. Thank you to anyone that takes the time to read this!
If you install WLED correctly and set the display up the way you want, save as a preset.
Configure WLED to use that preset on boot and you’re good to go.
The simplest test is get it all working as you think it should and then power it down completely and disconnect. Wait 10 mins, reconnect and power up. You should see your displays.
The presets and configurations are saved to flash, so you should be good over many many months (Espressif quotes data retention time at 20Yrs).
Try it over a few days (weeks?) of power down/disconnect to ease your mind.
That’s what I was thinking but just wanted some confirmation I guess. Thank you very much!
One other question I thought of as well. All these will be doing is alternating red/white. How many leds can I get away with on a single gpio pin? Trying to make wiring as simple as I can for him and have them all daisy chain together with plenty of power. If I have to go with more than one data line it will get a little more complicated. It’s 5 candy canes with 2 / 50 led strips each for a total of 1000
Take a look at the KB recommendations under: Multistrip.
If you’re talking a simple effect, try setting it up with no physical LEDs attached and see what the FPS looks like w/peek.
The Long Data section of the KB might have some good ideas as well for multi/long strip.
