Im working on project using a nano , i run out of memory,

Im working on project using a nano , i run out of memory, (just exactly 100% ram ), still room for code .
is there any way i can trim something from the fasted library that could save me some 200 bytes?

why nano?, because i still have a bunch of them.
thank you

Ram or flash? Also, I’d need to see your code (pastebin or gist, please) to tell you where you could trim. Note that the only things from FastLED that get compiled in is what you use. Anything you don’t use doesn’t get put in.

Agree (to see the code) but If you have tables of constants you could try moving them into progmem. It can be tricky if they are passed to libraries, as you might have to copy them into a buffer, or rewrite the library to use progmem.

Thankyou. I reduced ram usage by including some text messages on progmem, but as it is still 94% full , the code is unstable and now it reboots during the initial. Setup code …

can you share your code @Gustavo_K ?Unstable can be caused by running out of RAM (stack crashing). You can tell for sure if you put the code on a controller with a bigger memory and if the instability goes away, you know for sure.

i made it to work , only 200 bytes remaining on memory, but seams stable for now .
The question i have is , if there will be a reduction in memory usage if i convert everything to CRGBarray instead of the normal array .?

No - crgbarray is just an array of LEDs under the hood.
