<p>This allows for sharing an <a href="../../embedded_hal/spi/trait.SpiBus.html" title="trait embedded_hal::spi::SpiBus"><code>SpiBus</code></a>, obtaining multiple <a href="../../embedded_hal/spi/trait.SpiDevice.html" title="trait embedded_hal::spi::SpiDevice"><code>SpiDevice</code></a> instances,
|
|||
|
|
each with its own <code>CS</code> pin.</p>
|
|||
|
|
<p>Sharing is implemented with a <code>critical-section</code> <a href="../../critical_section/mutex/struct.Mutex.html" title="struct critical_section::mutex::Mutex"><code>Mutex</code></a>. A critical section is taken for
|
|||
|
|
the entire duration of a transaction. This allows sharing a single bus across multiple threads (interrupt priority levels).
|
|||
|
|
The downside is critical sections typically require globally disabling interrupts, so <code>CriticalSectionDevice</code> will likely
|
|||
|
|
negatively impact real-time properties, such as interrupt latency. If you can, prefer using
|
|||
|
|
<a href="struct.RefCellDevice.html" title="struct embedded_hal_bus::spi::RefCellDevice"><code>RefCellDevice</code></a> instead, which does not require taking critical sections.</p>

<p><strong>Warning</strong>: The returned instance <em>technically</em> doesn’t comply with the <code>SpiDevice</code>
|
|||
|
|
contract, which mandates delay support. It is relatively rare for drivers to use
|
|||
|
|
in-transaction delays, so you might still want to use this method because it’s more practical.</p>
|
|||
|
|
<p>Note that a future version of the driver might start using delays, causing your
|
|||
|
|
code to panic. This wouldn’t be considered a breaking change from the driver side, because
|
|||
|
|
drivers are allowed to assume <code>SpiDevice</code> implementations comply with the contract.
|
|||
|
|
If you feel this risk outweighs the convenience of having <code>cargo</code> automatically upgrade
|
|||
|
|
the driver crate, you might want to pin the driver’s version.</p>
