RGB LED PCB Help

[HeroXLazer]

So, I want to use a LED driver with RGB LEDs, and I want to use SMD RGB LEDs that only have four pins. They have a R pin, a G pin, a B pin, and a VDD/VCC pin. The driver I'm going to use uses Charlieplexing, and I'm confused on how to Charlieplex with single pins. I figured out to do it if you have two pins on each LED, but not with one pin. Could someone please explain how to wire it to the driver?

why don't you use ws2812b？

My guess would be cost and more importantly the lack of reverse mount option or some other size constraint.

I was going to, but then I thought about assembly.

Charlieplexing is really, really hard to describe.

A ws2812b is just as hard to stick on as a normal SMD LED.

You're going to have an easier time just using a standard matrix.

Yeah, because of that I just decided to use the ISFL3733, it's not charlieplexed. The hardest part is going to be firmware.
