# SD/MMC core 

This library is a core set of data structures and algorithms for SD/MMC support in embedded environments written in Rust.

## no-std support

`no-std` is supported by default. Any `std`-only features can be included by using the `std` feature.

## Compatibility

Data structures and algorithms in this library are meant to follow relevant specifications as closely as possible. Because of that, `sdmmc-core` should be re-usable in most projects with little-to-no changes.

The main specification followed is [`SD Specifications Part 1 Physical Layer Simplified Specification v9.10`](https://www.sdcard.org/downloads/pls/pdf/?f=Part1PhysicalLayerSimplifiedSpecificationVer9.10Fin_20231201.pdf).
