Cargo Features

[dependencies]
ist7920 = { version = "0.1.1", default-features = false, features = ["graphics"] }
default = graphics

The graphics feature is set by default whenever ist7920 is added without default-features = false somewhere in the dependency tree.

graphics default = embedded-graphics-core

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.
