Easing Demo doesn't work correctly with higher count of LEDs
Closed this issue · 1 comments
The easing demo works fine with the pre-set number of 60 LEDs, but when you raise that number (200 for example) the easing / lerping cause the lerpVal to skip numbers and thus not all of the LEDs will light.
Example output of lerpVal when using 200 LEDs with a 10ms delay:
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 2 2 3 3 3 3 3 5 5 5 5 5 7 7 7
Which obviously results in LED 1,4,6 not lighting.
This is a very useful demo for beginners, but you run into this issue as soon as you change the number of LEDs to a high enough value or lower the delay. I think it could be worth while to explain how to solve this problem.
I'm thinking of throwing in a generic disclaimer in my readme.md about the tested length of my demos. Some routines, like this one use 8 bit math and may not be appropriate for longer strands. I suspect we'd need a 16 bit easing/lerping in order to make this one not skip any LED's. Either that, or I'm going to have to lay off the Scotch and give it some real thought.
