74 / 98 page  When driving NeoPixels I cannot receive infrared codes on my IR receiver! Just like servos, the infrared library uses software interrupts to poll the IR LED, while the standard NeoPixel library blocks interrupts while NeoPixel are being updated. If you don't constantly update the NeoPixel, IR will work in between updates, but if you update them all the time, you will need to use another library and a microcontroller more capable than an Uno or Mega. Ideally one with DMA so that NeoPixels don't take up any CPU cycles. Marc MERLIN explains how to this depending on what chip you have (Teensy, ESP8266 or ESP32): http://marc.merlins.org/perso/arduino/post_2017-04-03_Arduino-328P-Uno-Teensy3_1-ESP8266-ESP32-IR-and- Neopixels.html (https://adafru.it/xA2) © Adafruit Industries https://learn.adafruit.com/adafruit-neopixel-uberguide Page 77 of 101 |
