Noob help SK9822

Bought the following hardware in hopes of putting these strips behind my rooted C1 TV.

LEDS: SK9822 (https://www.amazon.com/dp/B07BPYFB28?psc=1&ref=ppx_yo2ov_dt_b_product_details)
Controller: ESP8266 ESP-12 (https://www.amazon.com/dp/B0BK986HLZ?ref=ppx_yo2ov_dt_b_product_details&th=1)

Basically these were mentioned in the description of the following video (can google if curious hit link limit):
HyperHDR on Rooted LG OLED 65C1

But for the life of me I can’t find any wiring for the 4 pin led strip seems most use a 3 pin when it comes to this board and then you connect to the D4 pin for communication. Do I need to buy something different?

Thanks!

Just hookup both data and clock LED inputs two gpio pins and with in Wled’s setup choose apa102 as the type. Sk9822 use the same protocol.

If you experience flickering you’ll need a levelshifter. There’s a diagram on Wled’s wiki for using a levelshifter with two outputs: https://kno.wled.ge/assets/images/content/pic2.jpg

Thanks, that makes sense looking at it now. However I’m still having issues even after soldering the clock and data wires to the controller… seems the only way I get any life out of them is by tapping the joints with my fingers the main page presets and brightness settings do nothing. Not sure what’s going on there I think I might have to take another stab at it after some sleep as I’ve toyed with this far to long tonight now. From what I can tell from the random light show I was getting, there doesn’t appear to be any flicker.

How are you powering the Esp and the LEDs?

I’m using the following https://www.amazon.com/gp/aw/d/B07KC55TJF?psc=1&ref=ppx_pop_mob_b_asin_title

I’ve attempted running the esp off this /along side the LED strips and just via USB power from a USB phone charger.

Thanks again for your help!

Did your power supply, Controller and LED’s share the same ground?
Also if you are having flickering problems make sure you are using one of the newer firmware versions like 14 b4 - b6, as there was a flickering problem with one of the versions.

For the sake of hopeful clarity this is exactly how I’ve been testing it.

From the KB:

‘While using an ESP8266 and LEDs that have clock and data, you can either use hardware SPI (mostly faster) or software SPI. - hardware SPI: use GPIO14 (SCLK) for clock and GPIO13 (MOSI) for data. - software SPI: since all pins can be changed in the Hardware section of LED settings, you can use any pins. Recommend is to use GPIO1 (TxD) for clock and GPIO2 (D4) for data.’

Give that a try.

Thanks, I’m out of town until next Saturday so I’ll give that a try when I get back home.

Okay I got home early and got this working where it is responding to my commands via the following:

Recommend is to use GPIO1 (TxD) for clock and GPIO2 (D4) for data.

I am noticing that perhaps I have some flicker under certain conditions such as dimming so as you said I think I may need a level shifter. Thanks so much for your help.
