|
||
|
<p>This section covers how to upgrade an application written against RTFM v0.5.x to
|
||
|
the same version of RTIC. This applies since the renaming of the framework as per <a href="https://github.com/rtic-rs/rfcs/pull/33">RFC #33</a>.</p>
|
||
|
<p><strong>Note:</strong> There are no code differences between RTFM v0.5.3 and RTIC v0.5.3, it is purely a name
|
||
|
change.</p>
|
||
|
<h2 id="cargotoml"><a class="header" href="#cargotoml"><code>Cargo.toml</code></a></h2>
|
||
|
<p>First, the <code>cortex-m-rtfm</code> dependency needs to be updated to
|
||
|
<code>cortex-m-rtic</code>.</p>
|
||
|
<pre><code class="language-toml">[dependencies]
|
||
|
# change this
|
||
|
cortex-m-rtfm = "0.5.3"
|
||
|
|
||
|
# into this
|
||
|
cortex-m-rtic = "0.5.3"
|
||
|
</code></pre>
|
||
|
<h2 id="code-changes"><a class="header" href="#code-changes">Code changes</a></h2>
|
||
|
<p>The only code change that needs to be made is that any reference to <code>rtfm</code> before now need to point
|
||
|
to <code>rtic</code> as follows:</p>
