Function w5500_ll::spi::fdm_header_1b

pub const fn fdm_header_1b(address: u16, block: u8, mode: AccessMode) -> [u8; 3]

Helper to create a 1 byte fixed data length SPI header.

Example

SPI header to read the VERSIONR register in fixed data length mode.

use w5500_ll::{reg, spi, COMMON_BLOCK_OFFSET};

let hdr = spi::fdm_header_1b(reg::VERSIONR, COMMON_BLOCK_OFFSET, spi::AccessMode::Read);
assert_eq!(hdr, [0x00, 0x39, 0x01]);
