Let me try an attachment...

Work in progress - ie code not cleaned up yet. Also note the first comment wrt hardware requirements... And yes the output pin needs to be level shifted to 5VDC.

Good luck.

Make 'count' a 64-bit var.

Hi Andrew,

I just did an ESP32 xmas lights project with 600 leds. My suggestion would be for you to use https://github.com/Makuna/NeoPixelBus/

I used this after having used much slower (non-DMA) approached. I have run my on AdaFruit and Expressif ESP32s. This worked great.

If you need more help ...

I notice that the GitHub repo for ESP32 Arduino does have support for the ESP32-POE board BUT that: https://dl.espressif.com/dl/package_esp32_index.json does not. Is there some reason that https://dl.espressif.com/dl/package_esp32_index.json is out of date?

When will it be updated from GitHub ...
