APA102 NeoPixelBus example

[pruwait]

The problem

I can use esphome with fastled_spi light platform. But effect speed too low.

I want to use NeoPixelBus, but apa102 is not working with my code.

hardware: WT32-ETH01 + 74AHCT125N

Which version of ESPHome has the issue?

2022.1.4

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

core-2022.2.6

What platform are you using?

ESP32

Board

esp-wrover-kit

Component causing the issue

NeoPixelBus

May be I must to use SPI Bus component or another data/clock pins on this board... Need more information.

Methods esp32_i2s & esp32_rmt does not support dotstar. Hardware SPI pins 13+14, 18+23 is using with ethernet on this board.

NeopixelBus not working for WT32-ETH01 + dotstar.

I changed wire to pin 13 + pin 14 (hardwere spi). Neopixelbus works but so bad... FastLed works normally for esp32 + apa102.

With neopixelbus compiling have warnings:

And almost all operations working with errors. I cant change color or brightness normally. Only On/Off.
