Writing a SD Card driver in Rust
summary
Rust code implements an SPI SD Card driver that uses embedded-hal traits to send the actual six‑byte command frames, handles responses and CRC checks, and initializes cards over SPI; it reads/writes 512‑byte blocks via a blocking block‑device API and issues command 17 and 18 for reads, respecting the weird timing requirement of 74 clock cycles. A FAT implementation maps blocks to files, a few demos run, tests are slow, occasional corruption reports make it unsuitable for production without more testing.
