Required methods

fn write_read(
    &mut self,
    address: u8,
    bytes: &[u8],
    buffer: &mut [u8]
) -> Result<(), Self::Error>

Sends bytes to slave with address addr and then reads enough bytes to fill buffer in a single transaction

I2C Events (contract)

Master: ST SAD+W     O0     O1     ... OM     SR SAD+R        MAK    MAK ...    NMAK SP
Slave:           SAK    SAK    SAK ...    SAK          SAK I0     I1     ... IN

Where

  • ST = start condition
  • SAD+W = slave address followed by bit 0 to indicate writing
  • SAK = slave acknowledge
  • Oi = ith outgoing byte of data
  • SR = repeated start condition
  • SAD+R = slave address followed by bit 1 to indicate reading
  • Ii = ith incoming byte of data
  • MAK = master acknowledge
  • NMAK = master no acknowledge
  • SP = stop condition
