<h2 id="embedded-hal-async"><a class="doc-anchor" href="#embedded-hal-async">§</a><code>embedded-hal-async</code></h2>
<p>An asynchronous Hardware Abstraction Layer (HAL) for embedded systems.</p>
<p>This crate contains asynchronous versions of the <a href="https://crates.io/crates/embedded-hal"><code>embedded-hal</code></a> traits and shares its scope and <a href="https://docs.rs/embedded-hal/latest/embedded_hal/#design-goals">design goals</a>.</p>
<p>This project is developed and maintained by the <a href="https://github.com/rust-embedded/wg#the-hal-team">HAL team</a>.</p>
<h3 id="serialuart-traits"><a class="doc-anchor" href="#serialuart-traits">§</a>Serial/UART traits</h3>
<p>There is no serial traits in <code>embedded-hal-async</code>. Instead, use <a href="https://crates.io/crates/embedded-io-async"><code>embedded-io-async</code></a>.
A serial port is essentially a byte-oriented stream, and thats what <code>embedded-io-async</code> models. Sharing the traits
with all byte streams has some advantages. For example, it allows generic code providing a command-line interface
or a console to operate either on hardware serial ports or on virtual ones like Telnet or USB CDC-ACM.</p>
<h3 id="optional-cargo-features"><a class="doc-anchor" href="#optional-cargo-features">§</a>Optional Cargo features</h3>
<ul>
<li><strong><code>defmt-03</code></strong>: Derive <code>defmt::Format</code> from <code>defmt</code> 0.3 for enums and structs.</li>
</ul>
<h3 id="minimum-supported-rust-version-msrv"><a class="doc-anchor" href="#minimum-supported-rust-version-msrv">§</a>Minimum Supported Rust Version (MSRV)</h3>
<p>This crate is guaranteed to compile on stable Rust 1.75 and up. It <em>might</em>
compile with older versions but that may change in any new patch release.</p>
<p>See <a href="../docs/msrv.md">here</a> for details on how the MSRV may be upgraded.</p>
