@Daniel__Haber_twitter Maybe a silly question, but did you confirm what the color order was for the Ducenti and specify something different then default if needed? https://github.com/FastLED/FastLED/blob/master/examples/RGBCalibrate/RGBCalibrate.ino
Hard to say, but my guess would be not power but something else. Provide some more info and a link to your code on gist.github.com or pastebin.com Or ask your question with more info in the reddit group for more minds looking into your issue. http://fastled.io/r
sorry for going mia. So my code for this project is messier than a roomba spreading dog poop. I have to set up the whole thing again to confirm when exactly I'm seeing the flickering. For now, I can say that I have the line "LEDS.setBrightness(100);" in loop() (which i guess can just go in setup() ) and I am changing the brightness by changing the volume input in CHSV(h, s, v)
Hello, i'm having issues with ESP-32, WS2812 and WiFi (Webserver, OTA,...) .
What I've tried so far:
- Tried to use Logic Level Shifter 3,3V to 5V - no improvements
- Tried a small sketch (used Demoreel100) without WiFi etc. - works fine.
- As described in the Wiki I defined "FASTLED_ALLOW_INTERRUPTS 0" & "FASTLED_INTERRUPT_RETRY_COUNT 1" before the include - no success
For testing I'm using the Demoreel100 sketch. In some of the Patterns I was wondering whether its a feature or a bug. In the pattern sinelon it's pretty obvious: Some Leds are lighting up for a really short period of time, that are not supposed to light up. (The rest of the stripe doesn't stay dark(is flickering))
this is might be crazy because it's so basterdized but I've made a port of FastLED for esp-idf a little while back, for esp32 microcontrollers
and just today I made a port of that FastLED to support rgbw strips
Like, went through all the low level stuff, made the main object into CRGBW, added the extra byte everywhere, and added a new clockless controller for SK6812W, adding a new parameter in the clockless controller object that is the number of bytes, and send different things based on whether 3 or 4 bytes in that type of strip
it can be found here: https://github.com/eshkrab/FastLED-idf-rgbw
It's somewhat brute forced and the result runs slower than the original library, but in case someone wants it!
trying to run demo100 on a arduino due using the adafruit dotstar 8x8 matrix, however the due doesnt actually tell you what pins the spi pins are, so I have no idea what to put in the startup command. using the dotstar lib for the due you tell it to start without any pins at all, and it works! I was going to use a teensy but theres a power issue with it, that I think I need to supply a seperate 5 volt supply to get it to work.
On the Arduino Due, for hardware SPI, data on pin 75, clock on pin 76.

Forgot to put @firehoppr_twitter ...
I am using FastLED version 3.2.9 with an ESP32 on pin 27. According to the sourcecode in clockless_rmt_esp32.h the RMT peripheral is automatically used.
Anyway I get the message "No hardware SPI pins defined. All SPI access will default to bitbanged output" on the console. Is this ok?

Anyone tried the new Arduino Nano "Every" with the library. Can't even get a example to be compiled, since i get a "E:\tools\Arduino-1.8.x portable\portable\sketchbook\libraries\FastLED/fastpin.h:207:2: error: static assertion failed: Invalid pin specified
static_assert(validpin(), "Invalid pin specified");" error. Any suggestions?
Does anyone have suggestions or solutions to driving an LED strip with the TM1914 IC chipset? I am using a Teensy 3.2 microcontroller. I can drive the LEDs with a SP108E wifi controller and using the LED Shop app to create patterns etc. I want to use use a Teensy so use some sensors to trigger animations. Any ideas are welcome.
I feel silly, but even after researching on the wiki, faq, google etc. for a while I could not solve it: I am using the esp8266 which supposedly has a hardware SPI. But whenever I use the latest FastLED library it says, no hardware SPI pins defined and falls back to software SPI. Which works… but since the 8266 has hardware spi, I was wondering why I am unable to use it.
Or the esp8266 for that matter
delay(3000); // 3 second delay for recovery
Silly question maybe, but recovery for what?
If you have a mistake of some kind in your code where the first thing you do is, for example, turn on all the leds to full white and starve our power, causing the board to shut down then there’s no way to reprogram the board (in many cases) without completely removing it from the leds. That startup delay and wale gives you a window of time to reprogram the board before it starts doing something that it might not be able to recover from.
(there's other things that might leave a board in a state where it can't be programmed - for example, at least one board I worked on, if interrupts were disabled you weren't able to upload new code to it - so if something happened and got stuck while interrupts were disabled the board would effectively be bricked)
which is: Can I send data in parallel / simultaneously to 13 strips (all of varying lengths/ numbers of individual LEDs) of APA102 / SK9822 using an ESP which apparently only has 3 SPI pins.
*using an ESP32, each strip receives different data
I am also flexible wrt. to microcontroller, so I'd be willing to substitute the ESP32 for something else if it is a poor choice for parallel output using multiple APA102s
Hi there
I buy 6 of CJMCU-64-Bit-WS2812-5050-RGB-LED-Driver-Development-Board and I use the FastLED library.
The problem is that the every board work just until some LEDs
Is not work until led 64...
For example now I have a board that work until led 38... and after that
no led is open.
Is this defect or I wrong something please ?
I use NodeMCU 12e and also I put some codes before #include <FastLED.h> ...codes that I see on the FastLed help page:
define FASTLED_ESP8266_RAW_PIN_ORDER
define FASTLED_ESP8266_NODEMCU_PIN_ORDER
define FASTLED_ESP8266_D1_PIN_ORDER
So can anibody help me please ?
thanks a lot
I have a strip of ws2812b's that I can easily drive from my uno, but I can't for the life of me get the nodemcu 1.0 board to run them; at first I thought maybe 3.3v wasn't enough, so I got a logic level converter... still no dice... I can power the uno from the nodemcu and run the leds from there no problem, but as soon as I try to drive the controllers from the nodemcu, nothing happens... it seems like it should be dead simple, but connecting the data pin does nothing... at all... using example code, code I've gotten from github, anywhere... I've even tried the "define"s that denisjoshua above... any help would be appreciated... I'm going crazy
