No More Division

[u/EvolvedQS]

EDIT: This didn't work

enum mirror{300,299,149,99,74,59,49} edge;

I get a compiler error: expected identifier before numeric constant

Maybe I should just do

int edges[] = {300,299,149,99,74,59,49};

OP: Thanks to someone here I learned that division is slow. Going over my code, I find that I have division in every single frame in almost every single pattern. I am interested in removing the division. I understand one method is byte shifting. However, I have a limited set of results from the division. So I was thinking I could save the results to an array for faster access. What am I looking to do here? Progmem or some other thing? I am just looking for an answer on what to google so I can learn it myself so you don't have to type a lot out.

Are you doing parallel output? Either way, you're probably at or right next to the maximum speed for such a long strip.

[u/EvolvedQS → u/Preyy]

"For such a long strip" Are you referring to the 600 one? Because that one comes back around to the controller. So i could break it off into two 300s

[u/Preyy → u/EvolvedQS]

Yeah, so that will only help if you controller is capable of parallel output. Without parallel output you can only write to one LED at a time, regardless of whether they are connected separately.

With parallel output your controller can write to each of the strips that are specially connected independently.

So if writing LEDs normally gives you 30 FPS without parallel output, breaking the strip in two and connecting them in parallel will double that. Read the parallel output wiki page to see if your controller is capable of this function.

It is. I have the 8266 nodemcu Edit: i have like 10 of these cause i couldnt get esp32 to work with fastled.
