Struct Config 

#[non_exhaustive]
pub struct Config {
    pub mode: Mode,
    pub bit_order: BitOrder,
    pub frequency: Hertz,
    pub miso_pull: Pull,
    pub gpio_speed: Speed,
    pub nss_output_disable: bool,
    pub nss_polarity: SlaveSelectPolarity,
}

SPI configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

mode: Mode

SPI mode.

bit_order: BitOrder

Bit order.

frequency: Hertz

Clock frequency.

miso_pull: Pull

Enable internal pullup on MISO.

There are some ICs that require a pull-up on the MISO pin for some applications. If you are unsure, you probably don’t need this.

gpio_speed: Speed

signal rise/fall speed (slew rate) - defaults to Medium. Increase for high SPI speeds. Change to Low to reduce ringing.

nss_output_disable: bool

If True sets SSOE to zero even if SPI is in Master Mode. NSS output enabled (SSM = 0, SSOE = 1): The NSS signal is driven low when the master starts the communication and is kept low until the SPI is disabled. NSS output disabled (SSM = 0, SSOE = 0): For devices set as slave, the NSS pin acts as a classical NSS input: the slave is selected when NSS is low and deselected when NSS high.

nss_polarity: SlaveSelectPolarity

Slave Select (SS) pin polarity.
