Yep. The .get(n) method lets you access any raw entry in the circular buffer you like. There's also a Least Squares function, and one that uses that function to predict the value at some finite point in the future. I use it to control the heaters in my reflow oven to prevent overshoot.

| Sep 24, 2015 at 17:00 | comment | added | Majenko | The number of variables depends on the type of variable and how much space each entry takes up. I am always open to suggestions for enhancements to my libraries. | |
| Sep 24, 2015 at 16:44 | comment | added | orkes | Thanks for your reply! A few more questions. Given that I am running your code on Arduino Yun, am I right that the maximum number of elements I can store in the rolling set is limited to 2.5k (which is the size of RAM of ATmega32u4, where variables are stored)? Also, are you still working on your library? Any plans to further extend it with features I mentioned at the bottom of my previous post (e.g. querying sequences and patterns)? Thanks! | |
