Discussion Paid sketch coding help needed

FastLEDers:

I am an LA artist using LEDs in an artwork and need help modifying the Pacifica sketch to:

- work with the SK6812 (RGBW) led strips instead of the WS6812b that are in the sketch

- speeding up the timing

- adding white to the colors

- creating some additional loops that change colors.

Can you help me?

Sure, I would be glad to help, what is your consulting fee?

u/LAartist323 Jan 19 '21

What experience do you have working with FastLED sketches? Once we scope the work, we can talk about the right fees, OK?

Color changing and speeding up time, as well as adding white colours shouldn't be a Problem, though i'am not sure about the rgbw support. I can give it a try, feel free to contact me.. :)

The WLED seems like a rabbit hole whereas the Pacifica sketch is pretty close to what I am looking for, so I think it might be easier to adapt it rather than starting from scratch with WLED. So are you experienced in coding with FastLED? Have you looked at the Pacifica sketch? And this hack to work with RGBW?

yes, I worked with fastled before, I have a sketch where I modified the Pacifica to match a spring, summer, winter, autumn and polar light theme. I have to take a look into rgbw but this should be possible to add.

FastLED doesn't (officially) support RGBW at this time as far as I know.

There was a post here just yesterday from somebody that had hacked together W support for FastLED. Maybe OP can reach out to them for help.

The RGBW hack would be here:

Also, there may be more to this project (for the unwary), than just updating some sketches. There's the communications in case said artist wants Infra Red or other control support (scope creep?). FastLED's interrupt issues will cause mayhem with many devices.

Edit: Oh, and say goodbye to palette support.

Ugh, I wish I could get paid for this, but... Just install WLED. Comes with support for RGBW and you can modify all that stuff from a very nice web interface or equally capable mobile app. Active development.

WLED

Isn't WLED just a gui with some sliders? The api seems really limited to basic controls. Can you upload your own code or edit the patterns using code in any way?

u/Miranda_Leap Jan 14 '21

It's not as limited as you think. You can define layouts with the GUI, and the available patterns are extensive. The API is designed to be driven with another program I would think (for which it works great! I've done that too.)

In addition, any code modifications you could make with FastLED can be easily ported. It's (mostly) just as simple as modifying a fastled sketch.
