Module embedded_hal::blocking::i2c::transactional

Default implementation of blocking::i2c::Write, blocking::i2c::Read and blocking::i2c::WriteRead traits for blocking::i2c::Transactional implementers.

If you implement blocking::i2c::Transactional for your I2C peripheral, you can use this default implementation so that you do not need to implement the blocking::i2c::Write, blocking::i2c::Read and blocking::i2c::WriteRead traits as well.

use embedded_hal::blocking::i2c;

struct I2c1;

impl i2c::Transactional<i2c::SevenBitAddress> for I2c1 {
    fn try_exec<'a>(
        &mut self,
        address: i2c::SevenBitAddress,
        operations: &mut [i2c::Operation<'a>],
    ) -> Result<(), Self::Error> {
        // ...
    }
}

// This is all you need to do:
impl i2c::transactional::Default<i2c::SevenBitAddress> for I2c1 {};

// Then you can use `Write` and so on:
use i2c::Write;

let mut i2c1 = I2c1{};
i2c1.try_write(0x01, &[0xAB, 0xCD]).unwrap();
