Cargo Features

[dependencies]
max11300 = { version = "0.4.0", default-features = false, features = ["cs"] }
default = cs

The cs feature is set by default whenever max11300 is added without default-features = false somewhere in the dependency tree.

cs default = critical-section

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
