fn write_bytes(&mut self, words: &[u8]) -> Result<(), Error>
fn write_bytes(&mut self, words: &[u8]) -> Result<(), Error>
Write bytes to SPI.
Copies the content of words in chunks of 64 bytes into the SPI
transmission FIFO. If words is longer than 64 bytes, multiple
sequential transfers are performed. This function will return before
all bytes of the last chunk to transmit have been sent to the wire. If
you must ensure that the whole messages was written correctly, use
Self::flush.
fn read_bytes(&mut self, words: &mut [u8]) -> Result<(), Error>
fn read_bytes(&mut self, words: &mut [u8]) -> Result<(), Error>
Read bytes from SPI.
Sends out a stuffing byte for every byte to read. This function doesn’t
perform flushing. If you want to read the response to something you
have written before, consider using Self::transfer instead.
fn read_bytes_from_fifo(&mut self, words: &mut [u8]) -> Result<(), Error>
fn read_bytes_from_fifo(&mut self, words: &mut [u8]) -> Result<(), Error>
Read received bytes from SPI FIFO.
Copies the contents of the SPI receive FIFO into words. This function
doesn’t perform flushing. If you want to read the response to
something you have written before, consider using Self::transfer
instead.
