Expand description
This structure describes one SPI transaction
Fields§
§length: usize
< Total data length, in bits
trans_len: usize
< Transaction data length, in bits
tx_buffer: *const c_void
< Pointer to transmit buffer, or NULL for no MOSI phase
rx_buffer: *mut c_void
< Pointer to receive buffer, or NULL for no MISO phase.
When the DMA is anabled, must start at WORD boundary (rx_buffer%4==0
),
and has length of a multiple of 4 bytes.
user: *mut c_void
< User-defined variable. Can be used to store eg transaction ID.
