Esp32 spi ws2812
WebWith a few components you can convert a standard 1 MHz SPI data stream into a bit stream compatible with WS2812(B)-type addressable RGB LEDs (aka NeoPixels).... WebAssuming that you use the ESP32 Arduino Core, under the docs it is written that SPI is has a suppported Arduino API implementation. Thus using the Arduino SPI API, it should work, like all other devices (the ESP32 Arduino Core implementation conforms to the API defined by Arduino, of course I would check if your board's pinout corresponds to the Espressif …
