Required methods

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

Reads enough bytes from slave with address to fill buffer

I2C Events (contract)

Master: ST SAD+R        MAK    MAK ...    NMAK SP
Slave:           SAK B0     B1     ... BN

Where

• ST = start condition
• SAD+R = slave address followed by bit 1 to indicate reading
• SAK = slave acknowledge
• Bi = ith byte of data
• MAK = master acknowledge
• NMAK = master no acknowledge
• SP = stop condition
