//! HAL for the RP2040 microcontroller
//!
//! This is an implementation of the [`embedded-hal`](https://crates.io/crates/embedded-hal)
//! traits for the RP2040 microcontroller
//!
//! NOTE This HAL is still under active development. This API will remain volatile until 1.0.0
//!
//! # Crate features
//!
//! * **chrono** -
//!   Modifies some RTC access functions to use chrono types instead of a rp2040-hal specific
//!   DateTime type
//! * **critical-section-impl** -
//!   critical section that is safe for multicore use
//! * **defmt** -
//!   Implement `defmt::Format` for several types.
//! * **disable-intrinsics** -
//!   Disable automatic mapping of language features (like floating point math) to ROM functions
//! * **eh1_0_alpha** -
//!   Support alpha release of embedded-hal
//! * **rom-func-cache** -
//!   Memoize(cache) ROM function pointers on first use to improve performance
//! * **rt** -
//!   Minimal startup / runtime for Cortex-M microcontrollers
//! * **rom-v2-intrinsics** -
//!   This enables ROM functions for f64 math that were not present in the earliest RP2040s
//! * **rp2040-e5** -
//!   This enables a fix for USB errata 5: USB device fails to exit RESET state on busy USB bus.
//!   Only required for RP2040 B0 and RP2040 B1, but it also works for RP2040 B2 and above
//! * **rtic-monotonic** -
//!   Implement
//!   `rtic_monotonic::Monotonic` based on the RP2040 timer peripheral
