Trait esp32_hal::prelude::_embedded_hal_blocking_i2c_Read[−][src]

pub trait _embedded_hal_blocking_i2c_Read<A = u8> where
    A: AddressMode, {
    type Error;
    fn read(&mut self, address: A, buffer: &mut [u8]) -> Result<(), Self::Error>;
}
Expand description

Blocking read

Associated Types

Error type

Required methods

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
