<h2 id="differences"><a class="header" href="#differences">Differences</a></h2>
|
|
<p>Embassy provides both Hardware Abstraction Layers, and an executor/runtime, while RTIC aims to only provide an execution framework. For example, embassy provides <code>embassy-stm32</code> (a HAL), and <code>embassy-executor</code> (an executor). On the other hand, RTIC provides the framework in the form of <a href="https://docs.rs/rtic/latest/rtic/"><code>rtic</code></a>, and the user is responsible for providing a PAC and HAL implementation (generally from the <a href="https://github.com/stm32-rs"><code>stm32-rs</code></a> project).</p>
|
|
<p>Additionally, RTIC aims to provide exclusive access to resources at as low a level as possible, ideally guarded by some form of hardware protection. This allows for access to hardware without necessarily requiring locking mechanisms at the software level.</p>
|
|
<h2 id="mixing-use-of-embassy-and-rtic"><a class="header" href="#mixing-use-of-embassy-and-rtic">Mixing use of Embassy and RTIC</a></h2>
|
|
<p>Since most Embassy and RTIC libraries are runtime agnostic, many details from one project can be used in the other. For example, using <a href="https://docs.rs/rtic-monotonics/latest/rtic_monotonics/"><code>rtic-monotonics</code></a> in an <code>embassy-executor</code> powered project works, and using <a href="https://docs.rs/embassy-sync/latest/embassy_sync/"><code>embassy-sync</code></a> (though <a href="https://docs.rs/rtic-sync/latest/rtic_sync/"><code>rtic-sync</code></a> is recommended) in an RTIC project works.</p>
