| <p>The embedded ecosystem is full of different protocols, hardware components and |
| vendor-specific things that use their own terms and abbreviations. This Glossary |
| attempts to list them with pointers for understanding them better.</p> |
| <h3 id="bsp"><a class="header" href="#bsp">BSP</a></h3> |
| <p>A Board Support Crate provides a high level interface configured for a specific |
| board. It usually depends on a <a href="#hal">HAL</a> crate. |
| There is a more detailed description on the <a href="../start/registers.html">memory-mapped registers page</a> |
| or for a broader overview see <a href="https://youtu.be/vLYit_HHPaY">this video</a>.</p> |
| <h3 id="fpu"><a class="header" href="#fpu">FPU</a></h3> |
| <p>Floating-point Unit. A 'math processor' running only operations on floating-point numbers.</p> |
| <h3 id="hal"><a class="header" href="#hal">HAL</a></h3> |
| <p>A Hardware Abstraction Layer crate provides a developer friendly interface to a microcontroller's |
| features and peripherals. It is usually implemented on top of a <a href="#pac">Peripheral Access Crate (PAC)</a>. |
| It may also implement traits from the <a href="https://crates.io/crates/embedded-hal"><code>embedded-hal</code></a> crate. |
| There is a more detailed description on the <a href="../start/registers.html">memory-mapped registers page</a> |
| or for a broader overview see <a href="https://youtu.be/vLYit_HHPaY">this video</a>.</p> |
| <h3 id="i2c"><a class="header" href="#i2c">I2C</a></h3> |
| <p>Sometimes referred to as <code>I²C</code> or Inter-IC. It is a protocol meant for hardware communication |
| within a single integrated circuit. See <a href="https://en.wikipedia.org/wiki/I2c">here</a> for more details</p> |
| <h3 id="pac"><a class="header" href="#pac">PAC</a></h3> |
| <p>A Peripheral Access Crate provides access to a microcontroller's peripherals. It is one of |
| the lower level crates and is usually generated directly from the provided <a href="#svd">SVD</a>, often |
| using <a href="https://github.com/rust-embedded/svd2rust/">svd2rust</a>. The <a href="#hal">Hardware Abstraction Layer</a> |
| would usually depend on this crate. |
| There is a more detailed description on the <a href="../start/registers.html">memory-mapped registers page</a> |
| or for a broader overview see <a href="https://youtu.be/vLYit_HHPaY">this video</a>.</p> |
| <h3 id="spi"><a class="header" href="#spi">SPI</a></h3> |
| <p>Serial Peripheral Interface. See <a href="https://en.wikipedia.org/wiki/Serial_peripheral_interface">here</a> for more information.</p> |
| <h3 id="svd"><a class="header" href="#svd">SVD</a></h3> |
| <p>System View Description is an XML file format used to describe the programmers view of a |
| microcontroller device. You can read more about it on |
| <a href="https://www.keil.com/pack/doc/CMSIS/SVD/html/index.html">the ARM CMSIS documentation site</a>.</p> |
| <h3 id="uart"><a class="header" href="#uart">UART</a></h3> |
| <p>Universal asynchronous receiver-transmitter. See <a href="https://en.wikipedia.org/wiki/Universal_asynchronous_receiver-transmitter">here</a> for more information.</p> |
| <h3 id="usart"><a class="header" href="#usart">USART</a></h3> |
| <p>Universal synchronous and asynchronous receiver-transmitter. See <a href="https://en.wikipedia.org/wiki/Universal_synchronous_and_asynchronous_receiver-transmitter">here</a> for more information.</p> |
