Fields§

§baudrate: Hertz§data_mode: Mode§write_only: bool

This property can be set to configure a SPI Device for being write only Thus the flag SPI_DEVICE_NO_DUMMY will be passed on initialization and it will unlock the possibility of using 80Mhz as the bus freq See https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/spi_master.html#timing-considerations

§duplex: Duplex§bit_order: BitOrder§cs_active_high: bool§cs_pre_delay_us: Option<u16>

On Half-Duplex transactions: cs_pre_delay_us % 16 corresponds to the number of SPI bit-cycles cs should be activated before the transmission. On Full-Duplex transactions: cs_pre_delay_us != 0 will add 1 microsecond of cs activation before transmission

§cs_post_delay_us: Option<u8>

< Amount of SPI bit-cycles the cs should stay active after the transmission (0-16)
