+# Liscening

+FastLED is MIT license.

+I intend my portions to be MIT license. AKA the don't sue me license.
+
+However, the Espressif HAL code is LGPL. Mostly, these are used as headers,
+not as code itself. There's very little of value there. If LGPL bothers
+you, I would propose a quick rewrite of those files, and submit a pull request
+that would be under MIT license.
+
+I am honestly not sure what happens to LGPL in this case. It's a component in an
+embedded system, which is morally a library, but it is clearly very statically
+linked.
+
+I don't intend to make any money off this, don't charge people, and do not intend
+the use for commercial art projects, so the use is safe for me. But don't say
+I didn't warn you.
