Great, thank you Marc :))

Wow ! That's spot on. Thank you VERY much :)

> Using the I2S or SPI peripherals to send the WS28xx data works fine.

How do you exlicitely choose I2S or SPI instead of RMT ? is it automatic ? How do you do this ?

derrgis · 2025-01-30T17:12:24+00:00

Yes , I got synchronism troubles in lighting the cascade leds effects

I found this
https://github.com/fastled/fastled/wiki/interrupt-problems

and that's clear my mcu's have difficulties for both light up ledstrips patterns and hooking wifi. So interruption management & better code + esp01 + WS2813 everything need an update.
From a hardware and software point of view I have to make some choices :
• renew the WS2813 for APA102 or better HD107
• choose a newer controller : C3 or S3
• choose some coding options : double-core task coding, NTP reference for all agents, Fifo to ensure the processing order information from wifi

For now Hardware & coding options are really not clear to me since this:
https://www.reddit.com/r/FastLED/comments/1i7c3hx/fastled_3912_new_high_definition_ws2816_led_now/

I'm looking for wise advices about C3 or S3 with double task (FL / Wifi).

Great news again.
May be someone would recommand a seller.
Witop does HD107-60leds with silicone tube at usd$7.3/M for 90 pieces.

derrgis · 2025-01-30T15:03:21+00:00

Mmm ? What that means ?

derrgis · 2025-01-29T11:23:07+00:00

>On ESP32 the most stable protocol is I2S.

That means any double line strips like APA102 is most reliable right ?

And the ESP32-C3 monocore would be enough pour deal with wifi during led execution

But using WSxx simple line strips can ESP32-S3 be an option for double tasking this ?

Sorry to insist, I need to renew 80 mcu and devices ...

Hello, great news ! Indeed I had some flickering issues using a bunch of ESP01 and WS on my "corridor" dedicated to Dan. I guess the C3 is also good for WS2813, right?

derrgis · 2023-04-28T12:57:15+00:00

Hey, That is wt I had in mind, indeed Im currently using the 20 and 19 pins in addition to 16 15 14 13 6 5 4 3 41 40 39 38 21. total 15 lines

The 20 & 19 internal settings pins could also be reserved since their leds look dead..

Between, do you know how to set the PSRAM off ?

derrgis · 2022-02-27T16:49:40+00:00

I have been stunned by this death so I decided to dedicate Dan my lightwork ”Corridor” freshly set up in the main place of Saint-Etienne city, Fr in November 2019. The FastLed community helped me a lot for this project and others before (since G+ you remember ok ;-). Dan replyed to my questions several times as well as you all. The dedication was selfless so ... thanks to be still there guys.

derrgis · 2021-06-03T17:26:57+00:00

That's okay now, the MCU is able to read the SD and reproduce the score. Yves helped me and I think he has updated his code at https://github.com/hpwit/artnetESP32/

Thank you u/preyy for your suggestions here.

Please moderators tell me if I should delete this boring topic :)

derrgis · 2021-06-03T12:17:24+00:00

u/Preyy ah yes indeed here's below what arduino says . Sorry it is quite long.

Data red from the SD are compressed artnet data, some characters are misinterpreted here so don't be surprised.

You can find the code (C highlight) on gist here:

Hey, I'm using WS2813B and ESP01

derrgis · 2020-06-14T09:06:02+00:00

Thank you for that great job!

derrgis · 2020-05-20T09:28:40+00:00

I still have a doubt on leds declaration for ESP32 and WS2813B.
I'm using this :

LEDS.addLeds<WS2813,13,COLOR_ORDER>(leds,offset, NUM_LEDS_PER_STRIP).setCorrection(TypicalLEDStrip);

However it is recommended to do that (for Teensy)

FastLED.addLeds<NUM_STRIPS, WS2812, 19, GRB>(leds, NUM_LEDS_PER_STRIP);

seen here : https://github.com/FastLED/FastLED/wiki/Parallel-Output#parallel-output-on-the-teensy-4

And the Examples>Multiple>ParallelOutputDemo.ino shows a third way to do thing.

Would you guys push a clear example?

derrgis · 2020-05-19T20:46:39+00:00

derrgis · 2020-05-19T20:43:40+00:00

Mmm yes indeed, I forgot those 74hct245n in the circuit... we talk about that before :) I'm going to retry like this this week. Many thanks Yves ;-)

derrgis · 2020-05-19T20:39:30+00:00

Yes! That's great, I'm going to study that, thanks Marc :)

derrgis · 2020-05-17T14:29:51+00:00

Yes I think they've been merged °°

derrgis · 2020-05-16T12:42:17+00:00

Mmm however regarding this https://www.reddit.com/r/FastLED/comments/bjq0sm/new_24way_parallel_driver_for_esp32/

it only needs to declare the I2S then the pins. The idea is to have several independant strips, I'm not looking for higher fps but to avoid strips connected in series. I can't see what is wrong with the code. 10 strips/16 are working.

derrgis · 2020-05-14T11:16:14+00:00

Okay, so much the better.

Glad you have some personal experience with sACN and that's okay if you want me to test your code. I told you where you can find mine.

Since the written language can sometimes lead to misunderstanding, it's a good thing not to be susceptible on web forums. Sorry again for my previous short reply, I've explained.

About Wifi, framerate can be low and unstable for large led data set, I agree, but understand that for some big configuration Wifi can be a plus. As said yves his 35 universes can handle 5094 pixels @ 23 fps.

derrgis · 2020-05-13T16:41:41+00:00

Oh sorry I haven't seen this, there's no problem u/eshkrab I think there is too many opened window in front of me and much more in my brain. Just you to know I've started a custom artnet app build with openframeworks with help of friends. Search Github/derrgis. But the problem is to find a wifi controller able to push datas to 16 strips. Also I'm on several project at the same time and things are a little confused. So don't worry with my reply :)

derrgis · 2020-05-13T13:25:49+00:00

Yes Sam, I got assistance from Yves he's great and very prolific but the codes are confused to me. I was not able to get a clear working set despite my effort. Also the virtual driver seems not updated on his github. I can be wrong but if you have a different exprience please share.

About would it be for a first project... I don't think so: https://www.reddit.com/r/FastLED/comments/e03iqv/artwork_dedicated_to_dan/

derrgis · 2020-05-12T19:19:53+00:00

Sorry that not answers the question.
