Extra configuration for SD SPI device.

Fields

host_id: spi_host_device_t

< SPI host to use, SPIx_HOST (see spi_types.h).

gpio_cs: gpio_num_t

< GPIO number of CS signal

gpio_cd: gpio_num_t

< GPIO number of card detect signal

gpio_wp: gpio_num_t

< GPIO number of write protect signal

gpio_int: gpio_num_t

< GPIO number of interrupt line (input) for SDIO card.

gpio_wp_polarity: bool

< GPIO write protect polarity 0 means “active low”, i.e. card is protected when the GPIO is low; 1 means “active high”, i.e. card is protected when GPIO is high.

duty_cycle_pos: u16

< Duty cycle of positive clock, in 1/256th increments (128 = 50%/50% duty). Setting this to 0 (=not setting it) is equivalent to setting this to 128.

wait_for_miso: i8

< Timeout value in the driver will be waiting for MISO to be high before sending commands. Possible values are the following: 0: default value (40ms); -1: no waiting (0ms); 1-127: timeout in ms; else: invalid value, default will be used. This can be used to speed up transactions in certain scenarios but should not be needed if correct pull-up resistors are used. Use with care on devices where multiple SPI slaves use the same SPI bus.
