Struct nrf52::i2c::TWIM

pub struct TWIM {
    registers: *const TWIM,
    client: Cell<Option<&'static I2CHwMasterClient>>,
    buf: TakeCell<'static, [u8]>,
}

An I2C master device.

A TWIM instance wraps a registers::TWIM together with additional data necessary to implement an asynchronous interface.

Fields

registers: *const TWIM

client: Cell<Option<&'static I2CHwMasterClient>>

buf: TakeCell<'static, [u8]>
