SPI init (microcontroller) stuck in TimeoutWaitNotBusy,

9

Looked at the init sequence and saw `0xFF` issued before `CMD0`, this [PR](https://github.com/rust-embedded-community/embedded-sdmmc-rs/pull/32) fixes the issue for me. Thanks!

Fix closing `File`s and `Directories`

4

This PR attempts to fix closing `Files` and `Directories`. The working principle is that each new `File` and `Directory` is assigned a unique `SearchId`. To close/delete them, instead of looking...

File `starting_cluster` has a value of zero within the `open_files`

2

I've found an issue when trying to close files and open them again. Basically what ends up happening is that upon opening the file, the [`starting_cluster` of the File initialized...

Add the option to skip waiting in the init sequence when issuing CMD0.

Looking at #32 and #33, at least some cards get stuck in `TimeoutWaitNotBusy` when trying to initialize them. #32 provides a fix, however it seems to break other cards' init...

Make `BlockSpi` take ownership of `SdMmcSpi`

2

The current `BlockSpi` API makes it quite difficult to pass ownership around because it borrows the underlying `SdMmcSpi`. This is especially unergonomic e.g. in RTIC, where a `Controller` could be...

SdMmcSpi::acquire should consume self, not use &mut ref

2

Currently SdMmcSpi::acquire returns a BlockSpi object which contains a mutable reference to the SdMmcSpi. This is a construct that is very hard to work with. I'm reading parts of a...

Default values for const generic parameters MAX_DIRS, MAX_FILES, don't work as expected.

4

Commit https://github.com/rust-embedded-community/embedded-sdmmc-rs/commit/566f2023653dace195a43b05a6429f47e6be8a50 added two const generic parameters `MAX_DIRS` and `MAX_FILES` to `Controller`. Those parameters have default values equal to the values used before, and the new docs say: "By default...

Make functions that modify underlying state through SPI receive `&mut self` instead of `&self`

8

Currently, `BlockDevice::read` and `BlockDevice::write` (and practically all functions in `SdMmcSpi` and `BlockSpi`) receive `&self`. Why is this done? In my opinion, they should receive `&mut self`, so that responsibility of...

Support for asynchronous I/O

I am currently experimenting with the nRF52 and using the [embassy](https://embassy.dev/embassy/dev/index.html) project. I intend to use an SD Card in the project. However, this library does not appear to support...
