SD/MMC Host description

This structure defines properties of SD/MMC host and functions of SD/MMC host which can be used by upper layers.

Fields§

§flags: u32

< flags defining host properties

§slot: c_int

< slot number, to be passed to host functions

§max_freq_khz: c_int

< max frequency supported by the host

§io_voltage: f32

< I/O voltage used by the controller (voltage switching is not supported)

§init: Option<unsafe extern "C" fn() -> esp_err_t>

< Host function to initialize the driver

§set_bus_width: Option<unsafe extern "C" fn(slot: c_int, width: usize) -> esp_err_t>

< host function to set bus width

§get_bus_width: Option<unsafe extern "C" fn(slot: c_int) -> usize>

< host function to get bus width

§set_bus_ddr_mode: Option<unsafe extern "C" fn(slot: c_int, ddr_enable: bool) -> esp_err_t>

< host function to set DDR mode

§set_card_clk: Option<unsafe extern "C" fn(slot: c_int, freq_khz: u32) -> esp_err_t>

< host function to set card clock frequency

§set_cclk_always_on: Option<unsafe extern "C" fn(slot: c_int, cclk_always_on: bool) -> esp_err_t>

< host function to set whether the clock is always enabled

§do_transaction: Option<unsafe extern "C" fn(slot: c_int, cmdinfo: *mut sdmmc_command_t) -> esp_err_t>

< host function to do a transaction

§__bindgen_anon_1: sdmmc_host_t__bindgen_ty_1§io_int_enable: Option<unsafe extern "C" fn(slot: c_int) -> esp_err_t>

< Host function to enable SDIO interrupt line

§io_int_wait: Option<unsafe extern "C" fn(slot: c_int, timeout_ticks: TickType_t) -> esp_err_t>

< Host function to wait for SDIO interrupt line to be active

§command_timeout_ms: c_int

< timeout, in milliseconds, of a single command. Set to 0 to use the default value.

§get_real_freq: Option<unsafe extern "C" fn(slot: c_int, real_freq: *mut c_int) -> esp_err_t>

< Host function to provide real working freq, based on SDMMC controller setup

§input_delay_phase: sdmmc_delay_phase_t

< input delay phase, this will only take into effect when the host works in SDMMC_FREQ_HIGHSPEED or SDMMC_FREQ_52M. Driver will print out how long the delay is

§set_input_delay: Option<unsafe extern "C" fn(slot: c_int, delay_phase: sdmmc_delay_phase_t) -> esp_err_t>

< set input delay phase
