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.
