So, this works, but it's kinda awkward to pass gTimebase all the way down to every beat function I depend on. I'm curious what people think of the idea of a FastLED.setTimebase(...); function for this use case. Global timebase would still be 0 by default, so no breaking changes, but would be great for a use case like this
Marc Miller
@marmilicious
@backus I like the idea. Can you explain it a tiny bit more?

Hi. Anyone know if support for ucs
Hi. Anyone know if support for ucs2904 is on the cards anytime soon? Thanks Tim
John Backus
@backus
Hey @marmilicious I'd be happy to. What would you like more context on, specifically?
Marc Miller
@marmilicious
@backus I'm just trying to clearly understand how you would envision it working. It's an interesting idea and leads to the question of if it could be a library thing or something better left to rolling yourself. Consider opening a new issue (I know it's not an issue but rather an interesting functionality suggestion) on github with the info you've provided so far and an example/sudo example. Could also post the idea to FastLED reddit group to see what others might think/suggest.
John Backus
@backus
@marmilicious gotcha. Ok, I'll look into doing that. Thanks for the input

Hello,
Using fastled with teensy 4.0, mocing fron teensy lc. Wanted to know if it was compatible with it (i2c): I had no problem on Teensy lc, but with teensy 4.0, i2c gets plenty of transmission error when .show(). Any idea ? Regards
Marc Miller
@marmilicious
@philippe488 See if this helps. If not post your question on the Reddit FastLED group with details about your setup. https://www.reddit.com/r/FastLED/comments/d9z2os/teensy_40_and_fastled_along_with_ws2811_ws2812_ws/?utm_medium=android_app&utm_source=share

Thanks. Going to reddit: in fact fast led work but, i suspect interruption is not released, so that

@philippe488
Sorry for sending to fast... new test in progress. May this come from i2c , as i found also some error without using fastled.show.

I wanna try to make the rgb led strip like novation launchpad, i made the 64 button like midi fighter but misinh the led

Hello Everyone
Im trying to figure out how to merge fastLED patters to mirror on multiple pins
Im a little lost :-)
Marc Miller
@marmilicious
@urkel27 Have you looked at the FastLED examples, this one in
urkel27
@urkel27
yes, i was trying to figure out how to merge it but finally got it :-)
and with neopixel too
I also have a kik room #fastled

@marmilicious
@urkel27 Glad you got it. Feel free to come ask questions on the Reddit group too. http://fastled.io/r

I know one of my upcoming task is to learn state machines. I'm looking to create a BLE controlled Teensy 3.2 with a HM-10 using some of the open source patterns at https://www.tweaking4all.com/hardware/arduino/adruino-led-strip-effects/. The issue is have so far is that some of the patterns never end, so there is no way to "interrupt" them unless state machines are used, i.e. colored bouncing balls pattern. Once I have the Teensy and HM-10 working efficiently, that will be my next goal.
I also created a Facebook community "FastLED and Neopixel"

@Flavourdynamics
If you need help with BLE, let me know. I just tackled that one a few weeks back.

Hi everyone, i'm new to arduino and fastled, but hoping to learn from all of you

Hello there. i am using a SK2812 with Warm white led. everthing works as expected apart from the red displays green and the green displays red. how do i change the colour order?
i think i fixed it. yes i did
:]
thanks for your help meowcatluke,. meowcatluke: you're welcome
meowcatluke
@meowcatluke
now i am unable to set the brightness of the LEDS :/
using FastLED.setBrightness(CRGB(255,255,255)); and dims all the pixels of the led
changing these values does nothing to make them any brighter.
only if i comment out the line of code FastLED.setBrightness(CRGB(255,255,255)); do the LEDS go back to full brightness.
Marc Miller
@marmilicious
Try using just a single value such as FastLED.setBrightness(128); // 50% brightness

128 =/ 50%

Anybody know if fastled supports the esp32 wrover-b modules out of the box? I've been having trouble getting a simple blink sketch to run. Same code runs flawlessly on an esp32 wroom module (the esp32 huzzah board from adafruit). Is the esp32 pin mapping based on a specific esp32 module? If so, should I start to think about porting?
Drew André
@drewandre
To clarify, the sketch runs on the wrover-b module but I don't see any data being written to the leds. Switch over to the esp32 wroom module and they light up. I don't have access to an oscilloscope so I'm not sure how to debug this
Marc Miller
@marmilicious
@drewandre I have only used the HiLetgo ESP-WROOM-32 ESP-32S. Try asking on the FastLED Reddit group as many more will see your question and hopefully someone there can help. http://fastled.io/r
Drew André
@drewandre
Sounds good. Thanks!
Leedan Johnson
@LeedanJohnson
Howdy all! Does anyone know if there is a way to force FastLED on an esp32 to use Software Spi instead of RMT. I think RMT is introducing some problems, but I would like to test without it to be sure.
Marc Miller
@marmilicious

Have you tried adding this line before the include line for the library?

define FASTLED_FORCE_SOFTWARE_SPI

include <FastLED.h>

I haven't tried it on ESP32. Let us know if that works.

Leedan Johnson
@LeedanJohnson
I have tried it, and am still experiencing the issue, but I honestly don't know how to tell which implementation is being used.
Marc Miller
@marmilicious
Ping the Reddit group, hopefully Sam there know's how it's working under the hood.

When working with 8bit math for noise + palette style animations, I see a lot of harsh jumps between colors especially at low brightnesses. I know this has been discussed before, so what keywords/general topics should I try searching for? should I look for a noise16 implementation? or is it the ws2812b chipset? should I try to blur more or maybe use a combo of additive color setting + fade to black? any pointers would help!
Marc Miller
@marmilicious
@drewandre The harsh jumps when brightness is scaled down is a downside of working with 8bit. Something that had 64 steps for example, which is scaled down to 25% suddenly only has 16 steps. This is another good question/discussion for the Reddit group if you don't mind asking there.

i developing free gui software to create pixel effect. Zero coding, just use effect video to auto create a effect txt file. tested with attiny85 8mhz total 1000 ws2812b. Since the output in txt file, then can put it in flash memory. RAM not a issue. Also can use for any arduino, raspberry Pi, or any microcontroller. I would like to integrate with fastled for auto generate the ino file together with the effect. i looking for mr. kriegsman the fastled creator

Sounds cool @vasan25 Please feel free to share what you are working on or questions about integrating things with the FastLED Reddit group. http://fastled.io/r
