# SPI Example

This example shows the use of the `Spi` component to create an SPI bus, attach a
device, and perform a simple addressed read transaction.

## How to use example

The example is intended primarily as a compile-time reference for the `Spi`
API. Update the GPIO assignments to match your hardware before flashing; the
address phase is driven on MOSI and the response is read on MISO.
