Cargo Features

cortex-m-rtfm has no features set by default.

[dependencies]
cortex-m-rtfm = { version = "0.5.3", features = ["heterogeneous", "homogeneous"] }
heterogeneous = microamp

Enables heterogeneous of cortex-m-rtfm-macros

homogeneous

Enables homogeneous of cortex-m-rtfm-macros

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
