In this tutorial, we will interface the WS2812 LED with STM32. The same process can be used for WS2812B also. I am going to use PWM with DMA to send the data to the LED. I will explain the steps along the way, and how they are related to the datasheet of the device. Let’s...
WS2801B strips have two data lines (data and clock), whereby individual LEDs can be addressed via the integrated SPI bus of the Raspberry Pi. This is different for the WS2812B models. These strips have only a single data pin, which is why before sending a lot more has to be calculated...

If the LEDs themselves are addressable then look at how many pins they utilize. If it's a 3-pin interface then they're most likely going to be WS2812b LEDs (or some variant) which utilize a fairly trivial timing-based protocol to encode bits or they're go...
Every WS2812B has a repeater build in. Max length is 5m so you could propably get away with just connecting the data wire. If you run in problems add a 33 ohm resistor inline (data) (near the LED). I've tried to run past the normal amount ICUE could ...

This independence makes FPGAs a fantastic candidate for controlling anything that requires tight timing. For example, theWS2812BLED (aka NeoPixel) requires a tightly timed stream of pulses to write data to them. When you use a microcontroller, you usually need to write some inline-assembly just...
We're also going to use a strand of full RGB Neopixel LEDs (WS2812B), so we can reproduce colours other than white and have control over every pixel. Warning: the power supply I've used in this project has screw terminals that connect to a live AC wire. If you don't feel confident...
