Struct i2c_msg 

#[repr(C)]
pub struct i2c_msg {
    pub buf: *mut u8,
    pub len: u32,
    pub flags: u8,
}

@brief One I2C Message.

This defines one I2C message to transact on the I2C bus.

@note Some of the configurations supported by this API may not be supported by specific SoC I2C hardware implementations, in particular features related to bus transactions intended to read or write data from different buffers within a single transaction. Invocations of i2c_transfer() may not indicate an error when an unsupported configuration is encountered. In some cases drivers will generate separate transactions for each message fragment, with or without presence of @ref I2C_MSG_RESTART in #flags.

Fields

buf: *mut u8

Data buffer in bytes

len: u32

Length of buffer in bytes

flags: u8

Flags for this message
