Additional context There are several I don't have that problem, my code is as below, on the instance i am using, sensors, binary sensors, light, power supply, ledc `esphome: name: esp32_bedroom I've tried different output pins on my ESP32 just in case something is wonky about the first one I tried. As a side note, WLED An ESP IDF based neopixel implementation for ws6812 led stripes using RMT with a library of effects - mirronelli/neopixel This fork of NeoPixelBus can be used as component under your EPS8266_RTOS ESP-IDF style project. 27 Sep 15:09 . One limitation of the APA102 high-level interface is that it does not provide independent control ESP32: Template class static callback method not located in IRAM even though marked to be so #321. This is far outside the Neopixel timing tolerance of 150 ns, so it leads to incorrect values in some of the pixels. Anything in the logs that might be useful . The features and Go to Files->Examples->ESP32->GPIO->BlinkRGB for an example of how to use the onboard RGB LED. ESP32-IDF. ESPHome version1. And I added a function. I can still detect touch, but I am no longer able to control the LEDs. This example uses Hardware SPI on the ESP32 // with options to use alternate pins for SPI and drive two SPI ports using the alternate // additional SPI hardware available on the ESP32. Set pixel color at buffer position from RGBW value. Connect your ESP32 development board to your computer using a USB cable. [EDIT] The NeoPixels are on a single GPIO25, use WS2812B’s. 1 Like.
