This value corresponds to 40 ms). Supports most Arduino platforms. To be fair, we’re not sure that [yves-bazin] has put together 20,000 LEDs yet, but he HAS demonstrated the feasibility of driving 20k LEDs all at once thanks to some editing of the FastLED I2S Public headers that need to be included in the I2S application are as follows: i2s. The reset delay has a coarse resolution of ~20us. ESP32 support for using both RMT and i2s. This library is a I2S Interface to drive WS2811/WS2812 and SK6812 LED strips. The important point is that such interfaces have a FIFO buffer, so the CPU's activities don't need to be exactly synchronous with the output signal. This post is older than 2 years and might not be relevant anymore More Info: Consider searching for newer posts This is what RAW I2S output signals for the counter look like: word-clock (yellow), bit clock (cyan), data (purple).
