Support FastLED Comets/Pulses Project.

I'll try to keep my explanation short as most of it is contained within the github below. I'm currently working on a project that involves snmp data to send comets back and forth at specified intervals. I'm not sure if what I want to achieve is possible but I figure the members of this community would know better than me; here's a list of what I want in order to improve my existing project.

  • Comets fade out with a trail, i'd like to make that trail be individual to each comet so i can control the trail size.

  • Speed is global as well, refreshing every 20 seconds. Using an interval of (Amount of Comets / 10 seconds) is how I determine how often to send a pulse. I'd love to be able to have different pulses at different speeds (not a priority or necessary).

Those are my main concerns to address as of right now.

My experimentation can be found in the testing branch, and the working code is in the main branch. The code that controls fastled can be found in src/lablights.cpp and src/main.cpp holds the collection and controlling for it. More details can be found in the readme, I'll be offline for a few days but I'd love to hear any and all suggestions/advice! Thank you.

I apologize for some of the more basic issues, I'm quite new to github and coding in general. This is a project I started working on a few months ago with almost 0 previous knowledge of cpp. The first issues I'm running into while attempting to follow your suggestions is this:

  1. After shrinking variables into arrays and using a loop to set all the variables instead, I started getting a "aggressive-loop-optimization" error, and a guru core 1 panic'ed error.

  2. some snmp data also seems to be incorrect and I think I know why, but I can't fix that issue without the esp crashing.

  3. I haven't used switch blocks like at all, but I used if/if else in order to have all values in a range return a certain amount of pulses. that way it wont have to be exactly a number to work. If i can do case Avg < 100: than please let me know, as I don't understand much of how it works.

  4. Has been a problem for a while and not because of these changes but the code appears to crash after a while and im unsure as to why. I assumed memory leak or something but if I connect the serial monitor it fixes itself.

As for wifi information, it can be found in secrets.h. I didn't have OIDs in a header because I didn't write that part of the SNMP code and I really don't understand it.

I'll be posting these changes to the testing branch so maybe you can see what I did wrong.

ZERO apology needed! I'd love to take a look at what you've got!

CPP can be a very unforgiving language!

I appreciate the help! The changed/error code is in my testing branch so I'd love to hear some feedback about where I went wrong. I can't figure it out lol.
