Struct SdioInterface 

pub struct SdioInterface<B: MmcBus, D: DelayNs> { /* private fields */ }

SDIO interface for esp-hosted.

Wraps an SdioCard. The card is (re)acquired by Interface::init after the runner pulses reset, so pass an un-acquired card from SdioCard::new_uninit.

Implementations

impl<B: MmcBus, D: DelayNs> SdioInterface<B, D>

pub fn new(card: SdioCard<B, D>, freq_hz: u32) -> Self

Create a new SDIO interface targeting freq_hz (clamped during acquisition).

Trait Implementations
