Expand description

I2C Message Struct: I2C transaction segment beginning with a START. A number of these can be transferred together to form an arbitrary sequence of write/read transfer to an I2C device. TODO: Import with bindgen from https://github.com/lupyuen/incubator-nuttx/blob/rusti2c/include/nuttx/i2c/i2c_master.h#L208-L215

Fields

frequency: u32

I2C Frequency

addr: u16

I2C Address

flags: u16

I2C Flags (I2C_M_*)

buffer: *mut u8

Buffer to be transferred

length: ssize_t

Length of the buffer in bytes
