When a uniform-colored addressable strip transitions from one color to another, interpolate math-only against a cached start color instead of reading each LED's current value back through the 8-bit stored byte. The old algorithm used led.get_red()/etc. every step as the source for the delta, which round-tripped through gamma uncorrect/correct and the 8-bit stored byte. At gamma 2.8, any pre-gamma value below ~27 rounds to stored byte 0, so small early-transition steps produced stored 0 and the next step read back 0, stalling progress until ~90% of the transition before a single step produced a large-enough pre-gamma value to clear the gamma threshold. Result: dark for the first 9s of a 10s fade, then jump on in the final 1s. Detect uniform start state in start() and take a cheap math-only lerp path when true, so the stored byte advances through each gamma threshold as smoothed_progress crosses it. Falls back to the existing per-LED read-back algorithm when the buffer is non-uniform (e.g. when transitioning out of an addressable effect).
Tests for ESPHome
This directory contains some tests for ESPHome.
At the moment, all the tests only work by simply executing
esphome over some YAML files that are made to test
whether the yaml gets converted to the proper C++ code.
Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.
When adding entries in test_.yaml files we usually need only
one file updated, unless conflicting code is generated for
different configurations, e.g. wifi and ethernet cannot
be tested on the same device.
Current test_.yaml file contents.
