|
|
<p>This part of the book introduces the Real-Time Interrupt-driven Concurrency (RTIC) framework
|
|
to new users by walking them through examples of increasing complexity.</p>
|
|
<p>All examples in this part of the book are accessible at the
|
|
<a href="https://github.com/rtic-rs/cortex-m-rtic/tree/master/examples">GitHub repository</a>.
|
|
The examples are runnable on QEMU (emulating a Cortex M3 target),
|
|
thus no special hardware required to follow along.</p>
|
|
<p>To run the examples with QEMU you will need the <code>qemu-system-arm</code> program.
|
|
Check <a href="https://rust-embedded.github.io/book/intro/install.html">the embedded Rust book</a> for instructions on how to set up an
|
|
embedded development environment that includes QEMU.</p>
|
|
<p>To run the examples found in <code>examples/</code> locally, cargo needs a supported <code>target</code> and
|
|
either <code>--examples</code> (run all examples) or <code>--example NAME</code> to run a specific example.</p>
|
|
<p>Assuming dependencies in place, running:</p>
|
|
<pre><code class="language-console">$ cargo run --target thumbv7m-none-eabi --example locals
|
|
</code></pre>
|
|
<p>Yields this output:</p>
|
|
<pre><code class="language-console">foo: local_to_foo = 1
|
|
bar: local_to_bar = 1
|
|
idle: local_to_idle = 1
|
|
</code></pre>
|
|
<blockquote>
|
|
<p><strong>NOTE</strong>: You can choose target device by passing a target
|
|
triple to cargo (e.g. <code>cargo run --example init --target thumbv7m-none-eabi</code>) or
|
|
configure a default target in <code>.cargo/config.toml</code>.</p>
|
|
<p>For running the examples, we use a Cortex M3 emulated in QEMU, so the target is <code>thumbv7m-none-eabi</code>.</p>
|
