Hey Guys, I am putting together a display for Christmas using the FastLED TwinkleFox library and I am getting an erratic display. I am controlling a 130 led WS2812B strip with an ESP-01 module. I modified the TwinkleFox code to use NeopixelBus library after reading about glitching one might encounter if it is not used (verified when I tried the Fire2012 code!). I have had beautiful results with TwinkleFox in the past using an Uno but using the ESP-01 is new this year. I have tried modifying the code to eliminate the ‘erraticness’ but still happening. Basically it seems to be displaying correctly except when the brightness of the pixel is lower the brightness itself is erratically varying widely at high speed. It’s staying the same color just jumping around a lot at high frequency. Sometimes a pixel varies a lot and then a few seconds later it’s normal. I tried adding #define FASTLED_ALLOW_INTERRUPTS 0 and #define FASTLED_INTERRUPT_RETRY_COUNT 0 but there was no effect. I’d really like to use TwinkleFox on ESP8266s for ease of programming, do you have any ideas as to how to fix this? I uploaded the sketch to:
I figured it out, it doesn’t like to run at 160MHz. At 80MHz it runs great.
