Neopixel / WS2812 Notes with the ESP-01

Posted on November 13, 2017

Reminders for using WS281x’s with the ESP-8266: Library: NeoPixelBus and wire them to the RX pin.  This lib works with Arduino IDE + ESP Board version 2.3.0 The pinout for the 5mm single pixels is here. They use Rgb instead of Grb!!! NeoPixelBus<NeoRgbFeature, NeoWs2813Method> strip(PixelCount,NEO_PIN); A large differential between output signal and Vcc won’t work for the 5mm […]

ESP-8266, EEPROM, and config registers

Posted on November 11, 2017

I’m not 100% sold on the idea that using byte-wise simulated EEPROM on the ESP – as opposed to some other SPIFFS system – is the ‘best’ way. But I have a lot of existing code that wouldn’t need much modification, so EEPROM it is. Differences from AVR / Arduino: It’s not EEPROM, but actually […]
